Added Modbus serial devices to EcoStruxure Panel Server are considered as ‘Connected’ when;- EcoStruxure Panel Server sends Modbus request to Slave Device- If the Slave Device answers something (Modbus Exception included), then slave is considered as ‘Connected’Therefore, it is possible for you to see the serial slave device as ‘Connected’ but no upstream communication or measurements visible due to settings issue.In this scenario, please double check the Modbus serial settings on both the slave device and EcoStruxure Panel Server are matching.
