Need to create an alarm when a Modbus point has a specific value.


I have analog Modbus value which has specific values when the system is in error.

0 No Error

1 Over Current Acc

2 Over Current DeAcc

3 Over Current Constant Speed

In the example above I need to define an alarm when the object has Value 2.

When using a Modbus analog value it is not possible to create an alarm when the value is a certain number, for example when the value is 2.


Instead of a Modbus analog value create a Modbus multistate input. To the Modbus multistate input  it is possible to connect a multistate alarm which gives you the possibility to create an alarm when the value is 2.
