Product details

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.

Frequently asked questions

What does the FM 'Limited by number of slots or number of connections' mean?

The Failure Monitoring (FM) capability is constrained by the physical rack slots and the connections used. In practice, the maximum number of fail-safe modules you can monitor depends on the backplane and how many slots are populated with safety-relevant I/O.

What programming languages does this CPU support?

It supports CFC, SCL, STL, LAD, FBD, and GRAPH. The specific languages available are listed in the spec table and are consistent with a standard S7-400 CPU.

Does this CPU have an MPI port?

No. The MPI interface is not present. Communication is via integrated RS-485 for PROFIBUS and integrated PROFINET for Ethernet-based protocols.
