SM 521 digital input modules- Uniform display and diagnostics concept:
- Module status display for ERROR (red LED) and RUN (green LED)
- Channel status display for signal state log. "0" and log. "1" (green LED) or indication of wire break (red LED)
- Display for monitoring the 24 V DC supply voltage (green LED)
- Supported functions:
- Identification and maintenance data IM0 to IM3
- Firmware update
- Module-granular shared device and MSI (modular shared input);
in combination with PROFINET these allow assignment to several IO controllers - Channel-specific parameter assignment (only HF modules)
- Hardware interrupts (only HF modules)
- Channel-granular diagnostics (only HF modules)
- Isochronous mode (dependent on the module)
