If the module status shows an error, verify the I/O controller configuration. Also, check addressing.

What to do if module status error on AUMA Controller?
If the module status shows an error, verify the I/O controller configuration. Also, check addressing.
What to do if module status is idle on AUMA ACE C 01.2 Profinet?
If the module status is idle, check the I/O controller configuration.
What to do if network status Link port 1 or LED (LINK/ACT1) on Profinet board is illuminated in green on AUMA ACE C 01.2 Profinet?
If the Network status Link port 1 or LED (LINK/ACT1) on Profinet board is illuminated in green, it indicates a network connection towards the I/O controller is available, but there is no communication. In this case, verify the module status, and also check the cables and connection.
What to do if module status shows Process Devices waiting for I/O connection to I/O controller on AUMA Controller?
If the process devices are waiting for an I/O connection to the I/O controller, correct the parameter data within the I/O controller.
What does it mean if Channel 1 activity (uplink port) or LED (LINK/ACT1) is blinking on Profinet connection board on AUMA ACE C 01.2 Profinet Controller?
If Channel 1 activity (uplink port) or LED (LINK/ACT1) is blinking on the Profinet connection board, it indicates activity of the communication interface on channel/port 1 with valid telegrams, but not necessarily sent to its own address. Proceed to check the module status and network status.
What does it mean if Channel 2 activity or LED (LINK/ACT2) is blinking on Profinet connection board on AUMA Controller?
If Channel 2 activity or LED (LINK/ACT2) is blinking on the Profinet connection board, it indicates activity of the communication interface on channel/port 2 with valid telegrams, though not necessarily sent to its own address. Proceed to check the network status.
What does it mean if Network status Link port 2 or LED (LINK/ACT2) on Profinet board is illuminated in green on AUMA ACE C 01.2 Profinet Controller?
If Network status Link port 2 or LED (LINK/ACT2) on Profinet board is illuminated in green, it means that a network connection to the subsequent device is available, but there is no communication. Check the cables and connection.
