Issue
An analog Modbus value has specific values when the system is in error. For example:
- 0 = No Error
- 1 = Over Current Acc
- 2 = Over Current DeAcc
- 3 = Over Current Constant Speed
How could an alarm be defined to trigger when the object has Value = 2?

Cause
When using a Modbus analog value, it is not possible to create an alarm on a specific value.
Resolution
Instead of a Modbus Analog Value, create a Modbus Multistate Input. With a Modbus Multistate Input, it is possible to connect a multistate alarm which gives the option to create an alarm on a specific value.
