The nature of a counter also has implications for the type of event that can be triggered by it. See section “Events
(WHEN)”.
9.4.5 ADDING REGISTERS
To add a register click the
+
icon. This will create a new row with the same values as the current row. Enter the
Address and fill in the other fields as required.
9.4.6 EDITING REGISTERS
9.4.6.1 DISCRETE INPUTS AND COILS
Discrete Inputs and Coils can only have a value of zero or one. These can be enriched using the Str 0 Value and Str
1 Value columns.
9.4.6.2 INPUT REGISTERS AND HOLDING REGISTERS
By default, discovered Holding and Input registers will have a DataType of UINT16 when displayed. The user should
select the correct Data Type for each register.
9.4.6.2.1 THE ENUM DATA TYPE
“ENUM” stands for enumerated type. It means that the register can have a finite set of
named
values.
When entering ENUM data types, an entry must be made for each enum value. i.e. If there are 2 enums
representing ON and OFF, then 2 rows must be entered for the register.
In the example below, Register 614 is an ENUM type which uses Bit 0 to encode 2 possible states: 0 and 1, which
have enriched values of “OFF” and “ON”. Note how we use the combination of “Bit offset” and “Width” to specify
bit zero of the register.
