Step Description
2
After configuration, the client driver begins transmitting read and/or write commands to
the other nodes on the network. If writing data to another node, the data for the write
command is obtained from the module's internal database to build the command.
3
Presuming successful processing by the node specified in the command, a response
message is received into the client driver for processing.
4
Data received from the node on the network is passed into the module's internal
database, assuming a read command.
5
Status data is returned to the ControlLogix processor for the client and a Command List
error table can be established in the module's internal database.
Client Command List
In order for the client to function, the module's Client Command Lists must be
defined. Up to 100 individual entries can be defined for each of the four clients,
with each entry containing the information required to construct a valid command.
This includes the following:
Command enable mode ((0) disabled, (1) continuous or (2) conditional)
IP address and service port to connect to on the remote server
Command Type - Read or Write
Database Source and Destination Register Address - Determines where data
will be placed and/or obtained
As the list is read in from the configuration file and as the commands are
processed, an error value is maintained in the module for each command. This
error list can be transferred to the processor. The errors generated by the module
are displayed below:
