Solution
Check whether the AH500 system used is
powered.
AH10COPM-5A is downloading a network
configuration, and waits to complete the
downloading of the network configuration.
If the green light is blinking when the AH500
series CPU module is running, users have to
1. check whether the bus cable on the
CANopen network created is connected
correctly.
2. check whether the serial communication
speed of the master station selected is
the same as the serial communication
speeds of the other slave stations.
3. check whether the slave stations
configured are connected to the network
created.
4. check whether slave stations are offline.
No solution is required.
