MODBUS_TCP_PORT [-Pppp] [-Cconn] [-Ibaseindex] [-TKs] [-RKr] [-RTKt]

Definition of communication data.

NOTE: This command must necessarily be entered in the file.

ppp

port number to be used [default 502]

MODBUS_TCP_PORT -P503 -C18

conn

number of possible connections [default 16]

baseindex

From RTE 34.24.23

can take the following values:

•-1 (default if omitted) SYS_CFG.5 is used to determinate if initial index of units is 0 or 1

•0 initial index of units is 0 (non-standard value) regardless of the status of SYS_CFG.5

•1 initial index of units is 1 (standard value) regardless of the state of SYS_CFG.5

s

Time in seconds of inactivity before sending the first Keep Alive

r

Number of Keep Alive retransmissions to consider dropped connection

t

Time between two Keep Alive retransmissions to determine connection status

DATA_MODE mode

Definition of the manipulation type of received/sent data. The imposed value applies to all definitions present.

The default value (MODBUS standard) is MIDDLE_BIG_ENDIAN.

This command must be entered in the file before the block definitions

mode

BIG_ENDIAN es. HH HL LH LL

LITTLE_ENDIAN es. LL LH HL HH

MIDDLE_BIG_ENDIAN es. LH LL HH HL

MIDDLE_LITTLE_ENDIAN es. HL HH LL LH

DATA_MODE BIG_ENDIAN

ZEROS_STRING_STUFFING

This command allows you to change the handling of the transmission of strings shorter than the expected area by entering 0 as the terminator.

Instead, the default value is SPACE_FILLED meaning that any missing characters are filled with the space character

ERROR_ON_REPORT

Enables the generation of messages in the REPORT in case of communication and/or comprehension errors.

We recommend the use of this command in case of the first connection

WP_INFO_ON_HR

Enable association of write protected variables associated with holding registers (see below)

RUN-TIME_INFO

Enables the generation of messages in REPORT with the description of exchanged messages.

It is recommended to use this command in case of first connection

From RTE 34.16.3 via the keyword WP_INFO_ON_HR inserted in the same configuration file, the following variables can also be accessed:

•AM()

•INP_W()

•OUT_W()

•ALN

•ALS

NOTE: In case of writing read-only units, the operation will not be performed and diagnostics will be issued in the report.
