Comfort Click Jigsaw 3 and PLC bad communication
I would like to address an issue regarding the Comfort Click Jigsaw 3 device and the PLC controller. Communication is carried out through the Modbus TCP protocol. The initial problem involves the mobile application displaying the online status of the Comfort Click device, but it lacks successful communication with the PLC controller. Changes in values within the application do not reflect corresponding alterations on the PLC controller. This issue has been temporarily resolved by halting the operation of the PLC and restarting it, but it reoccurs after some time.
The second problem occurred today in the form of the unavailability of the mobile application. When attempting to log in to the device, an error is displayed: "Error connecting to server." Additionally, on the Comfort Click web platform, I noticed that the status of my controller is marked as offline.
I kindly request your expertise in diagnosing and resolving these issues.

I would like to add that comfort click works perfect few days and then suddenly this problems occurs. First problem is solved with stopping and starting PLC again, and second problem is solved with turning off power supply of comfort click and then turning it back on. But stopping and starting PLC and physically restarting Comfort click are not solutions I would like to resolve these problem so they do not occur anymore.
