Modbus Communication between CI867 and Siemens IED 7SJ82

We are communicating AC800M Controller (CI867) with Siemens Relay 7SJ82 with 'ETH-BA-2EL' card. But there is time out message (7006 error code) for both analoge and digital signals.

We have checked data types and different function codes.

While same CI867 is also communicating with other devices (26 no of devices) like ABB M2M.

800xA Ver. 6.0.3
