Help - Configure Communications

Overview

The "Configure Summary" page provides an overview the current configuration of the communications subsystem. This is divided into the following sections:

Servers
Data Table Expanded Register Map
TCP Clients
Generic Clients

Data Table Expanded Register Map

config servers

This lists the data table expanded register map values used. This includes:

The mode (disabled or incremental).
A table listing the configured unit IDs and the resulting calculated register map offsets.

Servers

config servers

The servers table lists the active servers. The items of data include:

The name of the server as assigned in the configuration file.
The server protocol.
The IP port used.

TCP Clients

config clients

The TCP clients table lists the active TCP clients. The items of data include:

The connection name as assigned in the configuration file.
