How can a safety interlock system be installed or configurated to deactiviate/de-energize a machine similiarly to the way an e-stop does?
A Safety PLC (Safety Interlock System) acts as highly intelligent safety relay. Some the fundamental requirements to meet the standards are the same such as dual channels and verify outputs, but with a configurable PLC based safety system has additional requirement that have to be met. Additional diagnostics in PLC that actually check the condition of the wiring and internal diagnostics to check the logic and communication are required. The Estop input rather than going into the safety relay now are inputs into the safety PLC and the PLC performs the Safety Logic and the PLC Safety Output shut off the coil of device you are deactivating (a safety rated interposeing relay between coil and PLC output is required) Siemens provides tools to assist with that, one is a Safety Integrated Function handbook that shows the wiring of an interlock system with a safety relay or connecting it to a safety plc and/or safety network.
