5 Operation
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.
5.2 Diagnosis
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
At the remote I/O there are supplement entries (see chapter Diagnosis in the System Manual
Compact Systems HI 800 140 E). These entries should help the user to configure and detect
errors in the line diagnosis.
Faulty parameter setting
• IOA: invalid LS/OC parameters on channel pair
• IOA: Invalid open-circuit or short-circuit monitoring time: (max. ... ms are allowed)
• IOA: Invalid open-circuit or short-circuit interval: (min....s allowed)
• IOA: Invalid open-circuit or short-circuit interval: (min....s 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
minus:0080]
The message specified above is only stored to the short-term diagnosis.
