Accessing Data via AOI

After setting up the AOIs you plan to use:

1. Download the program.

2. Set the PLC to Run mode.

If the device is properly set up, and does not have any trips or other events, the cyclic system AOI should indicate that the system is operational.

To view acyclic data, the appropriate explicit message must be accessed. See Calling Acyclic Data. As shown here, the device currently has one Minor Event logged via the System Minor Event Counter within the acyclic system diagnostic AOI.

This value can be reset by flipping the Minor Event Reset bit within the cyclic system AOI.

After a refresh of the acyclic system diagnostic data (see Calling Acyclic Data), the counter returns to 0.
