SINAUT 8-FW PCM : Configuration

 

 

Interface

For each channel any COM port ( COM 1 till COM 24 ) can be selected.

Modem

An individual modem can be installed and connected for each channel. LIAN 98 is able to process up to twelve modems in the range of COM1 till COM24 simultaneously. Select here the modem assigned to the selected channel. Normally this assignment will be recognized by LIAN 98 and the corresponding modem will be set.

Setup Modem

The settings of the modem must be executed via the windows control panel "telephone and modem options". With this button you can check the modem settings and see if they correspond to the LIAN 98 configuration.

Connection type

Attention, the connection type should be set to full duplex for monitoring !
 

Full duplex :

Most of the modems are full duplex and can transmit data in both directions simultaneously. DTE ( LIAN 98 ) and DCE ( Modem ) work simultaneously as transmitter and receiver. None of both transmitters has to wait for clearance for transmitting data. Therefore the signals RTS and CTS are not significant. Sure, LIAN 98 is setting the control signals RTS and DTR to 1 when it is ready for transmission and receipt but it does not check the signals CTS and DSR.

Half duplex :

In case of a half duplex connection DTE ( LIAN 98 ) as well as DCE ( Modem ) can work as transmitter and receiver, hereby only one data line ( 2-wire connection ) is available that can be used alternately for transmission or receipt of data. The control signals RTS and CTS are used in order to define the allocation of transmission or receipt. When LIAN 98 should work as transmitter it activates the signal RTS and waits for the confirmation of the modem via the signal CTS. After the receipt of the signal CTS the data are transmitted and after the transmission of the data the signal RTS is set to 0. In each other case LIAN 98 is working as receiver only.

As long as the LIAN 98 software is ready for transmission and receipt the signal DTR is activated in order to show the modem that LIAN 98 is ready for operation, as well the software expects an activated DSR signal from the modem.

RTS Leading delay

0 ... 1000 msec
This parameter ist only used for the connection type "half duplex" and is determined by the initial transient behaviour of the used transmission equipment.
The RTS Leading defines the delay time from activating RTS signal to transmitting the first character and is used for modems whithout the hardware handshake signals "RTS and CTS". In this case the "RTS signal" must be led back over the "CTS line" to the PC with the help of a brazing bridge in the monitor cable. Dependent of the used modem it may be necessary to connect additionally the DTR-pin with the DSR-pin.
This function is deactivated if the "Leading and the Trailing" is set to NULL and therefore the control signals are analyzed diectly from the modem.

RTS Trailing delay

0 ... 1000 msec
This parameter ist only used for the connection type "half duplex" and is determined by the final transient behaviour of the used transmission equipment.
The RTS Trailing defines the delay time from the last character transmitted up to the RTS signal is deactivated.
This function is deactivated, if the "Leading and the Trailing" is set to NULL.

 

Baud rate

Transmission speed : 25 - 115200 baud ( variable )

Data byte

8 bit ( fixed )

Stop bit

1 bit ( variable )

Parity

even ( variable )

Time out

1 - 9999 msec ( variable )

 

Transmission procedure
B :
balanced

If balanced transmission procedure is used, each station may initiate message transfers. The balanced mode is restricted to "point-to-point" or "multiple point-to-point". Balanced mode can be used in a full duplex transmission.

 


SINAUT 8-FW PCM : Simulation

 

SINAUT 8-FW PCM : RTI ( Master )-Simulation

 

 

 

 

Station number
( Address of the target station )

All telegrams to be sent are provided with the station number out of the SIM list during master simulation. If a station number unequal zero is inserted in the telegram ( TDB buffer ), the telegram will be transmitted unchanged with this number already inserted.

Response timeout

1 - 30 000 msec

A fixed time out interval is provided to be used for repeated transmissions. The time out interval and maximum number of retries are configurable and appropriate values will depend on the transmission system.

This parameter determines the time in milliseconds that the program LIAN 98 as master station at most has to wait for an acknowledge before the last transmission is repeated.

Number of frame retries

0 - 255

Via this parameter it is defined how many times the transmission is to be repeated when the reply is missing.

Send
start-up acknowledgement
command

yes / no

TDB buffer number where the organizational telegram ( CDH 03 ) is stored.

Send
MSC quittance
command

yes / no

TDB buffer number where the organizational telegram ( CDH 02 ) is stored.

Enable test procedure

yes / no

The test procedure is used to check the complete loop from the master station to the substation and back.

A test command is sent from LIAN 98 after the initialization of the communication and repeated cyclic when necessary, if this parameter is activated.

Test cycle time

0 - 255 seconds

Depending on this time LIAN 98 as master station will continually send the test command.

Test command

TDB buffer number where the test command ( CDH 01 ) is stored.

Enable general interrogation

yes / no

After the initialization of the communication LIAN 98 will transmit a general interrogation command and will repeat it cyclic ( GI cycle time ) when necessary, if this parameter is activated.

GI cycle time

1 - 1440 minutes

Dependent on this time LIAN 98 as master station will transmit the general interrogation command continually.

GI command

TDB buffer number where the organizational telegram ( CDH 06 ) is stored.

 

SINAUT 8-FW PCM : RTU ( Slave )-Simulation

 

 

Station number

All telegrams to be sent are provided with the station number out of the SIM list during slave simulation. If a station number unequal zero is inserted in the telegram ( TDB buffer ), the telegram will be transmitted unchanged with this number already inserted.

Response timeout

1 - 30 000 msec

A fixed time out interval is provided to be used for repeated transmissions. The time out interval and the maximum number of retries are configurable and appropriate values are depend on the transmission system.

This parameter determines the time in milliseconds that the program LIAN 98 as substation at most has to wait for an acknowledge before the last transmission is repeated.

Number of frame retries

0 - 255

Via this parameter it is defined how many times the last transmission is to be repeated when the acknowledge is missing.

TDB buffer number where the organizational telegram ( MDH 01 ) is stored.

 


SINAUT 8-FW PCM : Pre-filter/ Pre-trigger

 

 

 

SINAUT 8-FW PCM : Monitoring filters

 

Monitoring filters reduce capture on particular pre-defined data records. By setting the corresponding filters a carefully directed data preselection can be achieved, which results in a reduction of the data to be analyzed later.

 

 

Filter released

yes / no

With this option already set monitoring filters for one channel can be deactivated temporarily without deleting them.

protocol specific
filter mask

Here monitoring can be filtered for telegram specific values in which several OR-linked filter masks can be defined for the channel.

= Only values equal to 'from' are let through.
# Only values not equal to 'from' are let through.
< Only values less than 'from' are let through.
> Only values greater than 'from' are let through.
R 'from' and 'till' define a valid range
add Adds the next OR-element.
remove Removes the current OR-element.

 

SINAUT 8-FW PCM : Action filters

 

For the simulation and execution of data tests actions can be caused with the receipt of defined records. Therefore the possibility exists to define action filters, that effect the transmission of a send-sequence or transmit one or more message buffers ( TDB ).

 

 

Action filter released

yes / no

With this option already set action filters for one channel can be deactivated temporarily without deleting them.

protocol specific
filter mask

The action filter is described over telegram specific features corresponding to a filter setting. Additionally each action filter requires an allocation to a send buffer or alternatively to a send sequence.

= Only values equal to 'from' are let through.
# Only values not equal to 'from' are let through.
< Only values less than 'from' are let through.
> Only values greater than 'from' are let through.
R 'from' and 'till' define a valid range
Sendbuffer number
( from, from/ till )

In correspondence with the action filter the message buffer "from" or the message buffers "from/ till" are to be sent.

Sequence line number
( from, from/ till )

In correspondence with the action filter the send sequence is to be started at line number "from" or to be started at line number "from" and to be ended at line number "till".

add Adds the next OR-element.
remove Removes the current OR-element.

 

SINAUT 8-FW PCM : Start trigger

 

With the receipt of a telegram pre-defined as start trigger, recording is started.

 

 

Start trigger released

yes / no

With this option already set start triggers for one channel can be deactivated temporarily without deleting them.

protocol specific
trigger mask

Here you can define telegram specific start triggers for monitoring in which several OR-linked triggers can be defined for the channel.

= Only values equal to 'from' are let through.
# Only values not equal to 'from' are let through.
< Only values less than 'from' are let through.
> Only values greater than 'from' are let through.
R 'from' and 'till' define a valid range
add Adds the next OR-element.
remove Removes the current OR-element.

 

SINAUT 8-FW PCM : Stop trigger

 

Monitoring can also be stopped by telegram-specific filters and/ or "stop on error" after a defined number of following records. The number of the following records is defined in the field "records after stop on error/ stop trigger" in the global parameters of the VFL settings.

 

 

Stop trigger released

yes / no

With this option already set stop triggers for one channel can be deactivated temporarily without deleting them.

protocol specific
trigger mask

Here you can define telegram specific stop triggers for monitoring in which several OR-linked triggers can be defined for the channel.

= Only values equal to 'from' are let through.
# Only values not equal to 'from' are let through.
< Only values less than 'from' are let through.
> Only values greater than 'from' are let through.
R 'from' and 'till' define a valid range
add Adds the next OR-element.
remove Removes the current OR-element.

 


Each alteration in the settings is displayed by an asterisk * in the caption title and will be only effective after saving.

 


SINAUT 8-FW PCM : Message display format

 

The sent and received messages of all channels are entered binary into the archive file. Before displaying on screen, the binary archived data are coverted to an easily readable procedure specific plaintext. In order to optimize the representation it can be chosen between five different plaintext settings. The plaintext format is set separately for each channel.
( see also "FMT file - Display format" )

 

 

Plaintext format 1

Everything is displayed : Telegram header, telegram number and information elements

 

Plaintext format 2

No header is displayed : Only telegram number and information elements

 

Plaintext format 3

No header and telegram number is displayed : Only information elements are displayed

 

Plaintext format 4

No telegram number and information element is displayed : Only telegram header is displayed

 

Plaintext format 5

No information element is displayed : Only telegram header and telegram number

 

Additional to the plaintext output the transmission data can also be displayed in hexadecimal, decimal, ASCII, binary ( LSB first ) or binary ( MSB first ). Of course the plain text output can also be deactivated in order to display the transmission data only e.g. hexadecimal.

 


SINAUT 8-FW PCM : Error messages

 

Error checks during receipt

 

per character

the start bit, the stop bit and the parity bit.

per frame

the start character, the frame checksum and the end character and the
length ( 2 bytes ) and second start character in frames with variable length.

 

*** TimeOut !

Within a telegram, there may be no pause between characters. In case of timeout occurs it is assumed that it is the end of the telegram and the telegram check is started. The sensitivity can be parameterized in the configuration ( timeout ).
Normally a time out is no error, but it is stored in the PRO file together with the initial error for a better analysis of the faulty transmission line in connection with a line error.

*E: COM-PORT !

Error during writing on the COM port. May be it is already occupied by another program.

*E: Length !

The length of the telegram is wrong. For telegrams with fixed length the length is not 5.

*E: Format !

The repetition of the length or the start characters ( 68H ) in the message header are faulty, or the stop byte ( 16H ) is missing or set wrongly.

*E: Checksum !

The message checksum in the checksum byte is incorrect.

*E: SYNC !

The receive routine initially searches for 68H or 10H. Each other character is noted as synchronization error and inserted in the PRO file.

*E: Overflow !

Error message from the UART. This error is noted only in the PRO file.

*E: Parity !

Error message from the UART. This error is noted only in the PRO file.

*E: Start/ Stop !

Error message from the UART. This error is noted only in the PRO file.

 

Error checks during simulation

 

*E: unexpected !

The respond at this time was not expected.

*E: Link address !

The received station number is incorrect or the entry in the SIM list is wrong.

*E: Sequence !

The telegram counter ( MSC ) in the received telegram does not correspond to the MSC expected by LIAN 98. This error message can occur at the beginning after switching on the RTI simulation, when the MSC of the master and the substation are not still synchronized. Subsequently LIAN 98 takes over the new MSC of the received telegram and expects in the next telegram a MSC increased by one.

 


SINAUT 8-FW PCM : Parameter list

 

SINAUT 8-FW PCM : TypeID assignment list

Unfortunately the TypeID is not recognizable out of the Sinaut 8-FW telegram in monitoring direction. In the process system it is assigned data definitions to the telegram number. In LIAN 98 an unambiguous TypeID is defined for each data type in order to display the information ( indications, measurands ... ) in an easily readable plaintext and not only hexadecimal. With the help of the parameter list the correct typeID can be assigned to the telegram numbers. Assignments can vary from station to station. Process telegrams in contol direction and organizational telegrams are unambiguous and must not entered in the parameter list.

 

 

line

Line number : ( 1 ... 512 )

STA from

Station number from : The assignment is valid for that station, if the parameter "STA till" is not specified. Otherwise, the assignment applies to all stations in the specified range.

STA till

Station number till : If this parameter is specified, the assignment is valid for the entire range of stations.

con

Control direction : If this parameter is set to 1, the telegram number / type assignment is valid for telegrams in control direction. Otherwise, for telegrams in monitoring direction.

TNR from

from telegram number : The assignment is valid for that telegram number, if the parameter "TNR till" is not specified. Otherwise, the assignment applies to all telegram numbers in the specified range.

TNR till

till telegram number : If this parameter is specified, the assignment is valid for the entire range of telegram numbers.

TypeID

Type of information : Type identification number for the process information in control or monitoring direction.

 

The state of the delivery of the list is only to see as an example and certainly needs to be adapted to your plant. The definition of the telegram type numbers you will find in the S8FW chapter <Telegram structure>.
