4 Data received from the server is passed into the module's internal database,

if the command was a read command. General module status information is

routinely returned to the processor in the input images.

5 Status data for a specific Client can be requested by the processor and

returned in a special Client Status block.

6 Special functions, such as Command Control options, can be generated by

the processor and sent to the Client driver for action.

5.2.4 Client Command List

In order for the Client to function, the module's Client Command List must be

defined in the SIE Client x Commands section of the configuration. This list

contains up to 16 individual entries, with each entry containing the information

required to construct a valid command. This includes the following:

 Command enable mode: (0) disabled or (1) continuous

 IP address and service port to connect to on the remote server

 Slave Node Address

 Command Type - Read or Write

 Database Source and Destination Register Address - Determines where data

will be placed and/or obtained

 Count - Select the number of words to be transferred - see reference based

on processor type

 Poll Delay - 1/10

seconds

For information on troubleshooting commands, see Client Command Errors

(page 130).
