Siemens 6ES7274-1XF30-0XA0 SIMATIC S7-1200 SIM 1274 Input Simulator
An eight-switch 24 V DC input simulator assigned to the integrated digital inputs of SIMATIC S7-1200 CPU 1211 and CPU 1212 variants.
Product Identification
6ES7274-1XF30-0XA0 is the compact eight-switch SIM 1274 accessory for designated CPU 1211 and CPU 1212 controllers. It lets commissioning personnel apply repeatable digital input states to the CPU face while testing program behavior under a controlled procedure.
The narrower eight-input version should remain separate from the fourteen-switch XH30 execution used with larger CPU classes. It provides no outputs or analog simulation and does not replace the need to prove the real field circuit before production operation.
Keep the complete XF30 MLFB with the CPU catalog number and input test sheet. Visual similarity to other SIM 1274 accessories does not establish CPU fit.

Functions
Set states
Creates eight manual on/off conditions at the controller input interface for approved program tests.
Repeat scenarios
Allows a recorded switch pattern to be reproduced during commissioning, training or fault isolation.
Limit scope
Keeps simulation restricted to digital inputs; field outputs and analog channels require their own safe test method.

Applications
CPU 1211 program checks
Bench or panel testing of configured integrated input logic before field wiring is placed in service.
CPU 1212 maintenance
Repeatable confirmation of input addressing and interlocks after controller or project work.
Controlled troubleshooting
Input-state simulation where machine motion is inhibited and the site test plan defines expected responses.
Lifecycle
Match
Confirm that the installed controller belongs to the CPU 1211 or CPU 1212 class assigned to this simulator.
Prepare
Archive the project and create an input-state matrix with the expected logic response for every test step.
Exercise
Install under the approved equipment state and move only the switch named by the test sheet.
Close
Remove the simulator as required, restore the field-input path and prove the actual circuit before production.
FAQ
