Why can't I select Module Number for my ECOM module?
The ECOM needs to have a unique IP Address other than 255.255.255.255 or 0.0.0.0.
Why doesn't my ECOM show up in the Node List even though I can see it in NetEdit?
The ECOM needs to have a unique IP Address other than 255.255.255.255 or 0.0.0.0.
How many CIP connections are established between a C-more panel and a PLC?
C-more establishes a single TCP connection through which a single CIP connection is used. Consult your PLC manufacturer on the number of each available to your specific PLC model.
The CIP connection is released when the TCP connection is terminated in an orderly manner. If the connection cannot be terminated in an orderly manner, for example, power loss at the C-more panel, the connection will not be released until the Inactivity Timeout (configured in Panel Manager) is reached.
How many TCP connections are established between a C-more panel and a PLC?
One TCP connection is established for each C-more panel.
