6ES7216-2BD22-0XB0 functions and installation

Use separate checks for the AC CPU supply, DC sensing circuits and externally supplied relay loads. Document port assignments and preserve terminal identification before the controller is disconnected.

Sequence processingRuns the configured discrete-control program.

Field inputsAcquires DC digital input signals.

Output interfaceProvides relay-contact switching for field circuits.

Serial communicationUses the configured PPI or Freeport communication arrangement.

Installation and selection boundaries

Check the complete CPU ordering code before assessing stored program requirements.
Keep the code and data memory capacities separate in a project-size review.
Record the communication mode and settings used on each port.

Pre-order check 01

Installation environment

Use the installation drawing for the actual equipment and complete these checks before return to service.

Secure the machinery and isolate CPU and field-circuit power before disconnecting hardware.
Label terminal conductors and the two serial cable connections.
Compare the installed AC supply arrangement with the CPU nameplate.
Restore the accepted application and check serial communication before releasing the sequence.

Retain the approved installation drawing and record the controlled acceptance checks.

Pre-order check 02

Compatibility confirmation

Match the complete item, actual connections and required installed function.

CPU variant: Match the full ordering code rather than relying only on CPU 226.
Electrical execution: Confirm AC CPU power, DC input signals and the relay load circuits.
Program storage: Check code and data requirements against their separate capacities.
Serial settings: Retain each port mode, station settings and connected device requirements.
I/O assignment: Compare the application addresses with the actual terminal wiring.

Use this complete CPU variant as the memory and electrical reference, not a neighboring revision.
