Reverse PID mode in Modicon M241/M251

There is no input to select between direct/inverse direction at the PID function block from the Util library. The FB_PID function block (Toolbox library) is from Schneider and has additional features. With FB_PID function block from the Toolbox library in SoMachine to change the regulation direction user can use negative P-factor (i_rKp) The basic PID function must remain the same.

Can we use 800 IOs with Modicon m580 Safety System without impact TUV certification

There is no issue to use 800 series IOs without any impact on TÜV certificate on a M580 Safety configuration. As a general rule, all of Remote Distributed equipments on Ethernet allowed in M580 system could be considered as “non-interfering” for Safety M580 modules. However, of course, 800 series IOs data are not supposed to be used to perform safety functions.
