according to IEC61508, certified by TÜV. The SM810 is running a SIL3 certified
operating system and have a high degree of self-diagnostic including, for example:
• Double and inverted memory
• Double over voltage protection on internal voltages
• Two independent watchdog timers
• Oscillator supervision
• CRC on firmware and data storage
An SM811 or SM812 operates like an SM810 for SIL2 but can also together with
the PM865 or PM867 form a controller compliant with SIL3 according to
IEC61508, certified by TÜV.
The ModuleBus telegrams used in a High Integrity system with the S800 High
Integrity modules use the concept of long frames. Long frames are ModuleBus
telegrams that are extended with a safety header, comprising additional diagnostics
data and CRC32. S800 ModuleBus telegrams sent to the S800 I/O High Integrity
modules uses data from the PM865/PM867 and an inverted CRC32 from the
SM810/SM811/SM812. The I/O module checks that the safety header is correct.
Data received from the S800 I/O High Integrity modules over the ModuleBus have
the safety header independently verified by both SM810/SM811 and PM865 or
SM812 with PM867. Any CRC32 or other faults in the safety header will result in a
retry transmission and, if repeated, a shutdown of the faulty S800 I/O High Integrity
module.
