[?]: S7-300 CPU down compatibility
Posted: Wed May 23, 2018 1:35 am
Hi, is it possible to use an older CPU model as replacement for a newer model?
Can I replace a PLC with a CPU 313-5BG04-0AB0, with a CPU 313-5BF03-0AB0 spare unit?
If it is possible, what else should I look out for when commissioning?
