FIPIO PC104 had bad communications.
[Countermeasure]
First, the FIPIO PC104 board address may not be set to 0x330 (816 in base 10). Check the board address DIP switches. If the address is not 0x330, set the DIP switches to 0x330, or enter the DIP switch address as a base 10 number in system variable $FIPIOVAR.$IO_ADDRESS. Then check that the FIPIO PC104 board is securely installed on the PC104 motherboard. If errors occur frequently while the robot FIPIO PC104 board and PLC are securely connected, write down the error code (base 10, base 16) and contact the service center.
