Introduction
Internal constants
TLX DS COM PL7 xxE
This page describes all the configuration language objects in Modbus Plus communication that can be displayed by the application program.
The following table describes the internal constants:
Object
%KWxy.i.0
%KWxy.i.1
%KWxy.i.2
Function
Type
Station Address
Peer Cop
Meaning
Byte 0 = 14 for Modbus PLUS communication
Byte 0: station address
Byte 0 = 1: no Peer Cop service
Byte 0 = 2: Peer Cop service
%KWxy.i.4
Timeout behavior
Source address of specific outputs
%KWxy.i.5
Size of specific outputs for nodes 1 and 2
Byte 1 = 1: cleared inputs
Byte 1 = 2: inputs maintained at the last value
%KWxy.i.3
Destination address for specific inputs
Address of first internal word %MW used for receiving specific inputs
Address of first internal word %MW used for sending specific outputs
%KWxy.i.6
