In case of using the S7-1500 series, the communication does not work with firmware version 4.0.(connection not confirmed)

S7-1200 G2 series cannot be used.

Cause:
Communication is not possible with displays that do not support secure communication.

Secure communication is supported by the GP6000 series and IPC series (PC/AT, PS5000/6000 series).
Currently confirmed secure communication-only devices: (GP-Pro EX 5.01+ GP6000 series and IPC series can be connected)

Solution:
1. Please use a firmware version lower.

2. Only SIMATIC S7-1200 series firmware version 4.7.3 supports non-secure communication, so it can be used with all displays that support the TIA Portal driver (GP4000/SP5000/ST6000).
