![]() ![]() Both PLCs support distributed I/Os through Profibus. You need to shell out extra money for a PC Adapter (MPI) to work an ES in case of Siemens. Also AC500 connection can be configured directly through ethernet or serially. Profibus needs an extra comm card CM572, where as Siemens PLC only supports Profibus and needs extra CPs and licenses for Modbus and ethernet connectivity. Siemens also doesn't support IL, and needs optional packages like GRAPH and SCL to be supported by IEC 61131.ĬodeSys is a very flexible software tool for AC500 that allows ease of configuration and testing of programs though there isn't a great tool of cross references.ĪC500 CPU PM581 also supports ethernet and Modbus, and comes preloaded with blocks for these protocols. ![]() ![]() Siemens S7-300 is also very much designed for the same purpose - factory automation, special purpose machines, etc., but since the controller was engineered about 10 years ago and with Siemens not changing or upgrading its STEP 7 software, ease of use and configuration lies with the AC500 configuration tool CodeSys. It is totally IEC 61131 level 3 compliant supporting all languages (IL, ST, LAD, SFC, CFC). The AC500 is ABB's PLC version after the AC31 family of controllers specifically designed for factory automation.
