Users can monitor the error codes in the system log in ISPSoft, or the error code in the module error
code register in the AH500 series CPU module used.

AH10COPM-5A functions as a master station.
Code
AH10COPM-5A receives an emergency
16#A0E0
message from a slave station.
The length of a PDO that a slave station
16#A0E1 sends is not the same as the length of the
PDO set in the node list.
1 5 - 3 6
Description
AH10COPM-5A is normal.
Bus fault
Master station: The control of
the errors in a slave station is
not sent after a set period of
time.
Slave station: AH10COPM-5A
does not send a heartbeat
message after a set period of
time.

Description
Solution
No action is needed.
1. Check whether the CANopen bus
cable used is a standard cable.
2. Check whether the both ends of
the CANopen bus used are
connected to terminal resistors.
3. Check whether the noise around
the CANopen bus cable used is
strong.
1. Check whether the CANopen bus
cable used is a standard cable.
2. Check whether the both ends of
the CANopen bus used are
connected to terminal resistors.
1. Check whether the bus cable on
the CANopen network created is
connected correctly.
2. Check whether the serial
communucation speed of
AH10COPM-5A is the same as the
serial communication speeds of
other slave stations.

Solution
Use the function block
CANopen_EMCY to read relevant
information.
Set the length of the PDO in the
slave station again, and then
download the setting to
AH10COPM-5A.
