Can't clear or read DO totalization on/off counter through HDD Read and Clear Area (0xF180B000)


Applies To:

GRV-EPIC-PR1

Versions Affected:

All versions


Symptoms:

For groov digital output modules that support totalization, the following commands do not behave correctly:

  • Get & Clear HDD Module Counter
  • Get & Clear HDD Module Counters
The expected behavior is returning the count value and clearing the count value for the specified channel. The observed behavior is returning zero and not clearing the count value.

This also affects directly reading the High Density Digital Read and Clear Area memory map area, 0xF180B000.

Workaround:

Read and clear a channel through the (Expanded) Digital Channel Read & Clear area (0xF02E0000).

Resolution:

Opto 22 has resolved this issue and will include the fix in an upcoming release.
