Appendix 1 Error Codes
3C17H Hardware failure • A hardware failure has been
detected.
Stop • Take measures to reduce noise.
• Check the mounting status of the CPU
module, SIL2 function module, and
safety function module.
• Format the memory. Write all files to
the CPU module. Then, reset the CPU
module and run it again If the same
error code is displayed again, the
possible cause is a hardware failure of
the CPU module or module (SIL2
function module or safety function
module) connected. Please consult
your local Mitsubishi representative.
