Versions Affected:

Versions affected: PAC Control R9.5a and higher.
PAC firmware R9.5a and higher.
Problem is fixed in version: R9.6a

Resolved In Version:

Problem is fixed in version: R9.6a


Symptoms:

Based on input from PAC Control, the control engine may incorrectly identify the following points on a SNAP-AIRTD-8U module as output points:

      Point Type                  Range

  • 1k Ohm at 70 °F Ni      -46 to +148.9 °C
  • Auto-range Down           0 - 4000 Ohms
  • Auto-range Down           0 - 2000 Ohms
  • Auto-range Down           0 - 1000 Ohms
  • Auto-range Down           0 - 800 Ohms
  • Auto-range Down           0 - 200 Ohms
  • Fixed-range               0 - 200 Ohms
  • Fixed-range               0 - 100 Ohms
  • Fixed-range               0 - 80 Ohms
  • Fixed-range               0 - 40 Ohms
  • Fixed-range               0 - 20 Ohms
  • Fixed-range               0 - 10 Ohms
If you're affected by this issue, you may see these symptoms:
  • In the SNAP PAC REST API, the affected points will be displayed on the /device/strategy/ios/analogOutputs page instead of on the /device/strategy/ios/analogInputs page.
  • In PAC Control R9.5a (or higher), if you've used the new "Send Values" feature for filter, offset, or gain in the Add Analog Point dialog box, the system will ignore these values for the affected points.
