Proxy Ext (Client Numeric Bits)

This is the proxy extension for either a ModbusClientNumericBitsPoint (Numeric Bits Point) or ModbusClientNumericBitsWritable (Numeric Bits Writable).
It supports reading both Modbus holding register or input register values, and extracting bits specfied by the Beginning Bit and Number of Bits properties. The combination of these bits is the point’s value, as a StatusNumeric. The writable variant writes the point’s value into the raw register bits at the specified Beginning Bit relative position. Like other Modbus proxy points, both point-level or device-level polling is supported.

You access these properties by expanding ModbusAsynNetwork > ModbusAsyncDevice > Points in the Nav tree and double-clicking the ModbusClientNumericBitsPoint or ModbusClientNumericBitsWritable.

The ModbusClientNumericBitsPoint or ModbusClientNumericBitsWritable, has the following in addition to other Modbus client point Proxy Ext properties:

Property Value Description
Reg Type drop-down list Selects the type of register.
Beginning Bit a number from 0 to 15 Identifies the bit in the register where status information starts.
Number of Bits number from 1–16 Defines the number of bits used for this enum point.
