Data Concentrator not responding to CI867 card.
I am using a Data Concentrator Unit (ICD DC1000UE) for reading data from Multifunction meters (Schneider Conserv EM6436). Now using Modscan, I am able to read the data correctly. But the CI867 card is not able to read data from the data concentrator unit. In the Data concentrator, Rxd indication is blinking but not the Txd. MBTCPconnect block status is 1 but MBTCPRead status is showing error -7006.
Is it a fault with the data concentrator unit or some issue with the programming in Control Builder. Screenshots have been attached. Any suggestions are appreciated.
