Siemens 6ES7217-1AG40-0XB0 SIMATIC S7-1200 CPU 1217C DC/DC/DC Programmable Logic Controller

The Siemens SIMATIC S7-1200 CPU 1217C DC/DC/DC (6ES7217-1AG40-0XB0) is a compact PLC with 250 KB integrated work memory, 2 PROFINET ports, and onboard I/O of 14 digital inputs, 10 digital outputs, 2 analog inputs, and 2 analog outputs. It runs on 20.4-28.8 V DC and reaches 0.08 µs per bit instruction.

Selection Notes

The 1217C sits at the top of the S7-1200 CPU range with onboard 2 AI/2 AO and RS-422/485 interfaces not present on the smaller 1211C/1214C CPUs, so choose it when the application needs analog I/O or a serial point-to-point link without adding a signal module. The 250 KB work memory and dual PROFINET ports with an independent third port support larger user programs and line topologies that the base CPUs can't handle. The 4x 100 kHz high-speed digital outputs make it a candidate for onboard pulse-train positioning instead of a dedicated motion module.

Applications

Targets machine controllers that need onboard motion pulse-train outputs, analog process I/O, and a PROFINET-based multi-device network - packaging lines, conveyor systems, and skid-mounted process equipment - without expanding beyond the CPU's own I/O count for smaller machines.
