Operating Modes of the Network Module

At a Glance

The TSX ETY 5103 module has 4 operating states:

power off
self-test running
configured
not configured

Self-tests are performed on power-up.

The module does not operate with its default configuration.

The configuration must be sent to the PLC via the terminal socket and not over the network.

If the module has not been correctly configured, it cannot process the sockets and a refuse message is sent back to the TCP Open functions.

Sending the Configuration to the Module

The configuration is sent to the module in the following cases:

when an application is downloaded
when the PLC is powered up
when the module is connected to the rack when the power is on
on a warm or cold restart
when the Premium is reset

Operating Mode after Configuration

WARNING

UNINTENDED APPLICATION BEHAVIOR - WARM OR COLD RESTART

The programmer must test the system bits %S0 and %S1 in his application in order to re-create the connections if a warm or cold start has been performed. The programmer must also test the system bit %S13 in his application in order to check for first scan after a STOP/RUN command using the PLC software application.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Once a configuration has been defined, the module operates in the following way:

Step	Action
1	The module resets the communication in progress. Result: Exchanges in progress are ended; TCP Open connections are closed, and all sockets are deleted.
2	The module reconfigures itself.
3	The module is ready to process the TCP Open communication functions of the application.
