5 Operation and Maintenance
5.1 Start and Stop
After the PLC is programmed, start and stop it as follows.
To run the PLC:
1. Set the system to RUN.
2. Check that the RUN indicator light is solid ON in green
3. To stop the PLC, set the system to STOP. Alternatively, you can stop it in the
software tool of the host controller.
5.2 Burning User Program via SD Card
1. Save the program file created through InoProShop to the root directory of the SD
card (maximum capacity 32 GB, file formate FAT32).
2. Load the SD card into the TF expansion card and mount the TF expansion card to
the PLC.
Install the TF extension card with power off.
3. Power on the PLC again and burn the user program in the SD card into the PLC. The
RUN indicator flashes quickly at a frequency of 4 Hz during burning.
4. After the burning is done, the RUN indicator flashes slowly at a frequency of 1 Hz
and the PLC enters the STOP state. You can remove the SD card now.
If the ERR indicator flashes slowly, it indicates the burning fails. Check that the PLC
model configured in the program file is consistent with the actual PLC model. If the
problem persists, contact Inovance for technical support.
5. Power off and on the PLC again.
5.3 Upgrading Firmware via SD Card
1. Load the SD card (maximum capacity 32 GB, file format FAT32) to the TF expansion
card and then mount the TF card to the PLC.
