The remote I/O can only operated together with a controller. No specific monitoring is
required for remote I/Os.
5.1 Handling
Handling of the remote I/O during operation is not required.

A first diagnosis results from evaluating the LEDs, see Chapter 3.4.1. The remote I/O writes
diagnostic entries in the diagnostic memory of the connected controller.
5.2.1 Diagnostic
Entries
The remote I/O has extended diagnostic entry options. For more information, refer to the
System Manual for Compact Systems (HI 800 001 E), Chapter
Diagnosis.
These options
are intended to support the user when configuring the line diagnosis and detecting errors.
Faulty parameter setting
• IOA: wrong LS/LB parameters on channel pair
• IOA: wrong open-circuit or short-circuit monitoring time: (at maximum ... ms are allowed)
• IOA: wrong open-circuit or short-circuit monitoring time: (at minimum ... s are allowed)
• IOA: wrong open-circuit or short-circuit monitoring time: (at maximum ... s are allowed)
The messages specified above are stored to the long-term and short-term diagnosis.
Channel fault:
Each faulty channel is registered in one row of the diagnosis. This row identifies the
channel with the corresponding output/branch.
Example: Faulty channel 1 on both branches
IO CHANNEL ERROR: Slot:2 I/O module type:00C4 channel:1 status[L plus:0080 L
