4-6-5 Clearing Error Messages

Key Sequence
It is necessary to register the I/O table if I/O Units are changed, otherwise an I/O
verification error message, "I/O VER ERR" or "I/O SET ERROR", will appear
when starting programming operations.
I/O Table Registration can be performed only in PROGRAM mode with the write-
protection switch (pin 1 of the CPU's DIP switch) set to OFF (OFF="WRITE").
Group-2 HIgh-density I/O Units will not be displayed in the I/O table when it is
displayed using a host computer. Four asterisks (∗∗∗∗), indicating no Unit, will be
displayed instead.

After the I/O table has been registered, any error messages recorded in memory
should be cleared. It is assumed here that the causes of any of the errors for
which error messages appear have already been taken care of. If the beeper
sounds when an attempt is made to clear an error message, eliminate the cause
of the error, and then clear the error message (refer to Section 10 Troubleshoot-
ing).
To display any recorded error messages, press CLR, FUN, and then MONTR.
The first message will appear. Pressing MONTR again will clear the present
message and display the next error message. Continue pressing MONTR until
all messages have been cleared.
Although error messages can be accessed in any mode, they can be cleared
only in PROGRAM mode.
