RS485 only: Units under CAN teamwork must be free from CAN cables in between. You need to
prepare cables that support only RS485 communication. For how to make cable crimp terminals, refer to
the section of teamwork networking and monitoring.
Check whether the device number on the topology is the same as the actual device
number.
− If yes, go to 2.
− If no, check the cable connection and the settings of teamwork control parameters.
Check whether the number of the running devices on the topology is the same as the
actual device number.
− If yes, go to 3.
− If no, check the cable connection and the settings of teamwork control parameters.
Check whether the number of backup devices on the topology is the same as the actual
device number.
− If yes, go to 4.
− If no, check the cable connection and the settings of teamwork control parameters.
Check whether the number of online devices on the topology is the same as the actual
device number.
− If yes, the check is complete.
− If no, check the cable connection and the settings of teamwork control parameters.
