Can Step®7 programs from an S7-300/400 run directly on a Saia PCD®, or does anything have to be adapted?

FAQ #100035

 

Basically, yes. The operating system of the Saia PCD® xx7 series interprets Step®7 STL code. This means that a Step®7 program is executable in all STL based languages, such as LAD, FDB, Higraph, SCL and S7-Graph. Program modifications may be necessary when calling system functions specific to Siemens (e.g. special modules, such as communications processors) or accessing peripherals that are not present. For more details on system functions, see Technical Information TI 26/353 (xx7 operating system) under www.sbc-support.ch/xx7/xx7doc.htm .
