It could be the case that S7-1500 controllers are to communicate via the IEC 60870-5 protocols with telecontrol and substation control systems from different manufacturers.

The necessary information is provided in the various FAQ articles:

How can you implement the IEC 60870-5 protocols with the SIMATIC S7-1500?

Software download / Trial - SIPLUS RIC V1.7

SIPLUS RIC - Delivery release SIPLUS RIC V1.7

SIPLUS RIC IEConS7 : Functional Description Version V1.6 Upd4

If the IEC 60870 protocols are to be implemented with the SIMATIC S7-1500, then an S7-1500 CPU and the SIPLUS RIC library with the corresponding SIMATIC S7 Memory Card are required.

For example, the following configuration would be conceivable:

SIMATIC S7-1500, CPU 1511-1 PN, central processing unit with working memory 150 KB for program and 1MByte for data, 1st interface: PROFINET IRT with 2 port switch, 60 NS bit performance, SIMATIC Memory Card required.
