You can create a property on a Modbus device by polling a single bit or bit range of a data point.
Before you begin
What you should know
- The only data points that you can read a specific bit range for are input registers or holding registers. Coils and discrete inputs have a single bit.
- The plugin interprets the ordering of bytes within a Modbus register as big-endian. In the user interface, bit 0 represents the least significant bit and bit 15 represents the most significant bit.
Procedure
-
In the Data point section, select and input or holding
register, and click Edit data point of Modbus device
(
).
-
In the Bits fields, enter
the
values of the bits that you want to read.
