TLS encryption of the DNP3 protocol in SIMATIC S7-based telecontrol technology
TLS encryption for DNP3 communication is implemented via SIMATIC devices
(CP 1542SP-1 IRC, CP 1243-1 G2, TIM 1531 IRC).
An interface module TIM 1531 IRC acts as a central TLS gateway and
enables encrypted connections for control stations without TLS support.

Control of Inspekto system via hardwired digital I/Os using
SIMATIC S7-1200 G2
This application example demonstrates how the Inspekto vision
inspection system can be controlled through hardwired 24 V
digital signals, using a SIMATIC S7-1200 G2 PLC with integrated
relay-based inputs and outputs as an interface layer between
the Inspekto system and the main automation controller.

SIMATIC Library for Configuration Control (LCC)
The LCC library for TIA Portal provides blocks and PLC data types
for configuration control of S7-1200/1500 CPUs, ET 200SP CPUs
and ET 200 PROFINET IO devices.
Configuration control on a modular level sends control data records
to the CPU or IO device; for IO systems it uses the instruction
ReconfigIOSystem.
