ABB AC800M PLC AC 800M controllers
AC 800M High Integrity
AC 800M can easily be configured for usage in safety critical applications. The
main components of such a system are PM865, SM810/SM811, SS823 and the
S800 I/O High Integrity, running a High Integrity version of Control Software. The
PM865 processor unit has increased internal diagnostics, compared to PM864. The
added functionality on PM865 includes:
• Double over voltage protection on internal voltages
• A additional watchdog timer updated with data from SM810/SM811
• Increased oscillator supervision
• Support for S800 I/O High Integrity
• Support for SM810/SM811
• Increased system diagnostic and online self tests.
Benefits
