2.5 Limitations There are certain limitations and several options which must be considered in planning your installation. 2.5.1 Physical Limitations In a redundant EPLCG application, the primary and secondary EPLCG modules generally mount in the same rack, but cannot be located in the same dual node module. They are normally installed close to each other because of interlink or relay panel cable length restrictions. If your system uses an interlink cable, its length is fixed at 3 meters. Alternate cable lengths are not available. If your system uses a relay panel, the standard cable length to secondary EPLCG is 2m, but alternate cable lengths are available. However, if a longer relay panel cable is used, the amount added to the relay panel cable must be subtracted from each of the Port 1 and Port 2 cables. Obviously, the length of a substitute relay panel cable must be less than 15 meters (50 feet). 2.5.2 Single vs. Multidrop Cabling There must be only a single cable from a port to the PLC, modem, or communications controller that port is to service. If you want to use a Modbus protocol multidrop arrangement, you must place a local modem at the EPLCG with remote modems connected to each of the PLCs in the network. Allen-Bradley (A-B) protocol multidrop arrangements always connect through an AllenBradley communications controller (a CIM, for Communications Interface Module). Since this communications controller supplies the multidrop connections, only a single cable is needed from the EPLCG port to the A-B controller. 2.5.3 Cable Lengths The cables from the EPLCG ports cannot be longer than 15 cable-meters (50 cable-feet). If the distance to a PLC or communications controller exceeds this limit, you must use shorthaul modems. See subsection 2.6 for modem considerations.
