Power Panel PP41 DI138 input module is broken?

Hello.
Could you please advise on the following malfunction:
Power Panel PP41 controller-panel, ACOPOS 1090 drive is connected to it via CAN. The controller-panel stopped seeing inputs from the DI138 module. In list of logs and modules as far as I understand, there is no such error there Warning: CAN: ACK error - No acknowledge from other nodes and The project could not be found occur only when the panel is started, the project is displayed on the screen, the windows switch, the state of the inputs and outputs changes (except for the DI138 inputs).
The question is, what exactly is faulty, the controller panel or the DI138 module?
