9.2 Self-diagnostic Functions of MEWNET-F

When an error occurs when using [MEWNET-F], you can check the error with the self-diagnostic error
codes.
Procedure
FP programmer: Execute "OP-110".
FPWIN GR: Execute [STATUS DISPLAY].Error codes will be displayed on the screen.The description of
error codes are as below

slave station
Remote I/O terminal
51
station error
Remote I/O update
52
synchronous error
Note1) You can check where the error has occurred by monitoring the special data register with a
programming tool.
FP programmer: Execute "OP-8".
FPWIN GR: Execute "STATUS DISPLAY" or "DATA MONITOR".
Note2) You can select whether the CPU will halt or not when an error occurs by setting a system register.
(0: Continue, 1: Stop)

Actions
An illegal unit is installed on the slave
staiton.Remove the illegal unit.
Number of slots, number of I/O points exceeds
the limit.Use them within the limit.
Reset the I/O map so that the assignments do
not overlap.
Correctly set the registration value in the I/O map
for the FP I/O terminal board.
A communication error (such as the
disconnection of communication path or the
power off of remote slave station) occurs.Fix the
source of the error.
For the details of the method to check a slave
station which has produced an error, refer to "14-
4. Checking a Slave Station Which Has Produced
an Error". (OP8 -> DT9131(DT90131) to
DT9137(DT90137)
Verification error or error in an advanced unit, etc
Perform a check of the I/O unit.
(OP8 -> DT9131(DT90131) to DT9137(DT90137)
The setting of the terminal station for remote I/O
is incorrect.Correctly set the terminal station
again.
