Blitz Posted June 5, 2011 Report Share Posted June 5, 2011 I seem to have bumped to an undocumented limitations on I/O expansion module count per adapter (EX-A1 or EX-RC1). The hardware configurator allows us to place 8 ATC8 modules on the rail without error. (Also, note that with 8 ATC8, the 5Vdc power limit is not exceeded). However, we get an error message when we try to configure the entire 64 channels available. . The error start to appear on the 50th channel. Actually, when mixing a combination of digital and analog I/O modules, the limit appears to be 50 words. If 50 IO words is actually the limit, then it should appear on the documentations as it is an important information for sizing the PLC. We need the entire 64 AI channels per rail. Is there any work around aside from adding another adapter module? Thanks. Quote Link to comment Share on other sites More sharing options...
