Action
• Power off and on the NZ2GN-GFB.
• If this error occurs again, the possible cause is a
module failure. Please consult your local Mitsubishi
representative.
• The module will be automatically recovered
immediately after the error occurs. However, the stored
IP address and subnet mask are lost, and operation is
performed assuming that the following are stored.
IP address: 192.168.3.250
Subnet mask: 255.255.255.0
• Take measures against noise with a shielded cable for
connection.
• If this error occurs again, the possible cause is a
module failure. Please consult your local Mitsubishi
representative.
Turn on the power supply with the CC-Link IE TSN IP
address setting switches set to a value in the range 0 to
254.
• Change the 'Parameter area initialization command'
(1002H) from Off (no command) to On (Command) to
Off (no command), then turn off and on the NZ2GN-
GFB or reset the non-volatile memory parameters to
their default values. After that, set the parameters
again.
• Take measures against noise with a shielded cable for
connection.
• If this error occurs again, the possible cause is a
module failure. Please consult your local Mitsubishi
representative.
• The module parameters are not saved in the non-
volatile memory.
• Take measures against noise with a shielded cable for
connection.
• If this error occurs again, the possible cause is a
module failure. Please consult your local Mitsubishi
representative.
• Update the F/W of the NZ2GN-GFB using the F/W
update function.
• Take measures against noise with a shielded cable for
connection.
• If this error occurs again, the possible cause is a
module failure. Please consult your local Mitsubishi
representative.
Take any of the following actions, and then turn off and on
the NZ2GN-GFB or perform reset.
• Set the CC-Link IE Field Network station number
setting switch to 0.
• Set "Station-specific mode setting" to "Local station"
and then set the module parameters.
