Cause of error occurrence (details)
Model invalid has occurred between the
master and local/standby master stations.
• The mode differs between the master and
standby master stations.
• The local station is set to the remote net
additional mode, and the master station is
set to other than the remote net additional
mode.
• The local station is in the remote net ver.2
mode or remote net additional mode, and
the master station is in the remote net
ver.1 mode.
At the time of parameter setting with
dedicated instruction, an invalid value has
been set to switch 5 of the intelligent function
module switch setting.
At the time of parameter setting with
dedicated instruction, the station type of
other than the remote I/O station has been
set in the remote I/O net mode.
In the remote net Ver.2 mode or remote net
additional mode, total points for remote
stations set in the station information have
exceeded the maximum of 8192.
When the standby master station was
operating as the master station with the
master station duplex function, the network
parameter setting of the faulty master station
was changed.
The mode set in the control data of the
G(P).RLPASET instruction differs from the
mode set with the switch 3 of the intelligent
function module switch setting.
Parameter change was executed during
transient request.
A response from the requested station was
not returned within the watchdog time period.
A transient request was made to a remote
I/O station or a remote device station.
Or, too many transient requests were sent to
the corresponding station.
The receive buffer size of the dedicated
instruction is less than the response data
size.
The number of read/write points in the
control data of the dedicated instruction is
outside the setting range.
The station number in the control data of the
dedicated instruction is outside the setting
range.
Multiple dedicated instructions were
executed for the same station.
CHAPTER 15 TROUBLESHOOTING
Corrective action
After correcting the mismatch of
modes between the master and
local/standby master stations, reset
the CPU module.
Set a correct value to switch 5 of the
intelligent function module switch
setting.
Set all station types to the remote I/O
station.
Check the points for remote stations
in the station information setting.
Return the network parameter
setting of the master station to the
original value.
Check the control data of the
G(P).RLPASET instruction and the
switch 3 setting of the intelligent
function module switch setting.
Please consult your local Mitsubishi
representative.
Change the parameter after all
transient requests are completed or
before any are requested.
Set a longer watchdog time.
If an error persists, check the
requested module and cables.
Set the corresponding station to a
local station or an intelligent device
station.
Or, wait for a while and send the
request again (overload due to many
transient requests).
Please consult your local Mitsubishi
representative.
Check the receive buffer size.
Change the number of read/write
points to within the setting range.
Change the station number to within
the setting range.
Check the program.
