Description

Function Description

The SEND_TLG function is used to send telegram-type data to a remote application.

The data to be sent must be a maximum of 16 bytes in length. Unlike the other communication functions, this function is processed immediately (synchronous): there are therefore no activity bit and timeout parameters.

The integer table assigned to the management parameters therefore only uses two words instead of four (the exchange and timeout numbers being unnecessary).

WARNING

INOPERABLE FUNCTION - INVALID CONFIGURATION

Use the SEND_TLG function on a Fipway network only after installing a TSX FPP 20 card:

on channel 1 of the processor
for stations 0 to 15

Failure to follow these instructions can result in death, serious injury, or equipment damage.

The additional parameters EN and ENO can be configured.

Description of the Parameters

The following table describes the input parameters:

Parameter	Type	Comment
`ADR`	`ARRAY [0.. 5] OF INT`	Address of the destination entity of the exchange. Only the {Network.Station}APP or {Network.Station}APP.num addresses are authorized.
`EMIS`	`ARRAY [n.. m] OF INT`	Integer table to be sent to the destination device of the request. This must be a maximum of 8 integers (16 bytes) in length. Note: it is essential that the number of bytes to be sent is placed in the second word of the management table before executing the exchange.

Parameter

Type

Comment

ADR

ARRAY [0.. 5] OF INT

Address of the destination entity of the exchange. Only the {Network.Station}APP or {Network.Station}APP.num addresses are authorized.

EMIS

ARRAY [n.. m] OF INT

Integer table to be sent to the destination device of the request.

This must be a maximum of 8 integers (16 bytes) in length.

Note: it is essential that the number of bytes to be sent is placed in the second word of the management table before executing the exchange.

The following table describes the input/output parameters:

Parameter	Type	Comment
`GEST`	ARRAY [0 ... 1] OF `INT`	Table of words used to manage the exchange. This table is made up of 2 words: the report word and the length word for the data to be sent. The report comprises: the operation report (most significant byte of the first word), the communication report (least significant byte of the first word), The operation report takes one of the following values: 16#00: correct exchange, 16#03: incorrect address format, 16#04: incorrect destination address, 16#05: incorrect management parameters (for example length), 16#06: incorrect specific parameters, 16#07: module faulty, 16#0A: insufficient send buffer size, 16#0B: No system resources: the number of simultaneous communication EFs exceeds the maximum that can be managed by the processor, 16#0F: Telegram Service not configured.

Parameter

Type

Comment

GEST

ARRAY [0 ... 1] OF INT

Table of words used to manage the exchange. This table is made up of 2 words: the report word and the length word for the data to be sent. The report comprises:

the operation report (most significant byte of the first word),
the communication report (least significant byte of the first word),

The operation report takes one of the following values:

16#00: correct exchange,
16#03: incorrect address format,
16#04: incorrect destination address,
16#05: incorrect management parameters (for example length),
16#06: incorrect specific parameters,
16#07: module faulty,
16#0A: insufficient send buffer size,
16#0B: No system resources: the number of simultaneous communication EFs exceeds the maximum that can be managed by the processor,
16#0F: Telegram Service not configured.
