Hi All,

Regarding This, I have raised Siemens Request , i got reply that its not possible. we can't read Connection resource information. 

Siemens Reply shown below for reference.

With SFC 87 "C_DIAG" you can determine the current status of all S7 connections and all fault-tolerant S7 connections.
By suitable evaluation of this connection data, the failure of
S7 connections and fault-tolerant S7 connections can be detected and, if necessary, reported to an operator control and monitoring system. The monitored connections can be connections between automation systems as well as connections between an automation system and an operator control and monitoring system.

A detailed description of the SFC 87 can be found under the following link:

However there is no option to check no of connection resources used as shown in your snap
