SERVER ALREADY STARTED
The PLC logic attempted to start another
copy of the server on the same physical port.
If the error occurs while processing the Start
Network Services Command, the Network
Server was already started. Only one copy of
the server is required to service multiple
clients.
This is caused by a PLC logic error. It usually
occurs when you are triggering the command
more than once.
It also may occur when you AutoStart the
network server and also try to start the
network server from PLC logic.
