DIAGNOSTICS & PROTECTION

Use channel status information in the control program to identify missing field signals.
Four isolated input groups support structured separation of field circuits.
Check sensor supply and common reference before replacing the module.
Observe the documented input-voltage limits during troubleshooting.

INSTALLATION & UPGRADES

Designed only for SIMATIC S7-22X CPU expansion systems.
Preserve the original module position and input address allocation.
Use shielded cable up to 500 m or unshielded cable up to 300 m.
Run a complete input-state test after replacement or cabinet work.
