Cause
There is a communication or configuration problem with either the inputs or a formula in the Setup Registers of the Arithmetic Module.
Resolution
1. Hold Shift + right-click the input to the Arithmetic Module to check for n/a values or communication errors.
2. If one or more inputs show a missing value or have an error:
- If the input is from a device, either unlink it or resolve the communication issue.
- If the input is from another module, check the inputs to that module.
3. If the inputs all show a value and no errors are shown, edit the Arithmetic Module and refer to ION Reference to confirm the formulas are configured correctly.
4. If some n/a values are expected or can't be resolved immediately, consider setting N/A Conversion in the Setup Registers of the Arithmetic Module. This will convert n/a inputs to a specific value to allow the calculations to continue working.
