A
3140H END instruction
error • The END (FEND) instruction does
not exist in the program.
Stop • Check the detailed information (error
location information) of the error by
executing module diagnostics using
the engineering tool, display the error
program (step) by clicking the [Error
Jump] button, and correct the program.
• Take measures to reduce noise.
• Write the sequence program(s) and FB
program(s) to the CPU module again.
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.
