Hi people, I´m trying to conect a 3100-MCM Prosoft module attached to a PLC-5/40 as Modbus SLAVE to our SCADA systems. Protocol is Modbus Enron. I made my application based on Prosoft example MCM5EX1S. I´m trying to report some digital states from the digital input module of PLC-5 to coils in address 1001 to 1005 in the SCADA. Digital states (coils) are input to B11:0/0-4 (Function Code 1) I copied data from B11:0/0-4 to N10:20, and in word N7:8 I wrote 1001 but its not working. All words are based in their example. Does any one has experience with this module and tell me Where I tell in the module that the starting address for coils that the SCADA ask is 1001, i.e in what of the configuration words I write coils address. Thanks and regards, Ner P.S I contact Prosoft Technical Support to not avail.

Has anybody try or know how(or where to find information) to program RS-232 ports on Micrologix Family with AIC+ as Modbus Ascii (Enron) protocol. I´ve used some of the Prolinx gateways in the past, but despite they´re quite good they´re quite expensive (U$S 1000+). As an alternative if VB is available it can be program, but I don´t know if this feature is available on Micrologix.
