FUNCTIONS

6.12.2 Remote RESET

(1) Definition of Remote RESET

A remote reset is an operation that resets the CPU module using GX Developer when

the CPU module is in the STOP status.

Even if RUN/STOP/RESET switch is in RUN, the reset can be performed when the

CPU module is stopped and an error that can be detected by the self-diagnosis

function occurs.

(2) Applications of remote RESET

A remote reset can reset the CPU module using GX Developer when an error that is

beyond the reach of the CPU module occurs.

(3) Remote RESET method

Remote RESET operation can be performed by only GX Developer.

To perform the remote RESET, follow the following steps:

• When the CPU module is in RUN status, use remote STOP to arrange the STOP

status.

• Reset CPU module by the remote RESET operation.

For the GX Developer, this is performed by [Online] [Remote operation.]

(4) Precautions

(a) Remote RESET in RUN status

Remote RESET cannot be performed when the CPU module is in RUN status.

Perform remote RESET after placing the CPU module in the STOP status by

performing remote STOP or similar operation.

(b) Status after reset processing completion

After the reset processing is complete, the CPU module will enter operation status

set by the RUN/STOP/RESET switch.

• With the RUN/STOP/RESET switch in the STOP position, the CPU module

enters into the STOP status.

• With the RUN/STOP/RESET switch in the RUN position, the CPU module

enters into the RUN status.

Take care that Remote RESET does not reset CPU module if an error occurs in

the CPU module due to noise.

When the CPU module cannot be reset by the remote reset, either reset with the

RUN/STOP/RESET switch or restart-up the PLC.
