Limitations of CIP Messaging
The 1756-DHRIO module supports 32 connections per DH+ channel.
Up to 5 of the connections can be CIP connections. These 5 count
against the 32 connections. So if a 1756-DHRIO module has used 30
connections for DH+ Message Routing, it can only use 2 connections
to bridge a CIP message through the module on that channel.
