Issue
It is not possible to select a "Trend 10K3A1" Thermistor when configuring a central or onboard IO input point.
Product Line
EcoStruxure Building Operation
Environment
- Building Operation WorkStation
- Building Operation Automation Server (AS-P) Central IO
- Building operation Automation Server Bundled (AS-B) Onboard IO
Cause
The specific thermistor type is not available to be selected.
Resolution
Configure an input as a resistive Input with reliability level, electrical scale and engineering scale set to:
- Upper/Top: 0
- Lower/Bottom: 587628
Then use a Function Block 10K3A1-Ohm-To-C sample program or Script program to convert from resistance to °C.
NOTE Satchwell and Trend both use 10k3A1 Thermistors but the shunt resistance used within it will vary.
