Controller module
The Siemens 6AG1416-3ER05-4AB0 is an S7-400 CPU from the SIPLUS extended-temperature series. Its Failure Monitoring (FM) capability is limited by the number of slots or connections, so the safety logic reach scales with the rack configuration. The module is isolated, with 244 bytes each of process-input and process-output data.
Engineering languages
Programmable in CFC, SCL, STL, LAD, FBD, and GRAPH under STEP 7. The combination of CFC and SCL gives a team option to mix graphical flow-based configuration with structured text for complex math or sequence logic.
