There is ProfiSAFE for Profinet/bus, Failsafe over Ethercat (FSoE), Opensafety for Powerlink, but nothing tangible in the way of Modbus, although opensafety claims this could work.
I've read somewhere on this forum that Modbus is not suitable for safety application. Any source (books, research etc) on this?
More importantly, are there any workarounds to make modbus capable of SIL 2/3?
