Analog Input and Analog Output Point Groups
Note:
The total number of point groups configured in each MODBUS card must be less
or equal to 64.
Point Group
Adding an Analog Input Point Group or Analog Output Point Group to the node creates 16 floating-point
engineering units I/O points.
Start Address
A start address for the Point Group must be entered here to create a contiguous MODBUS message exchange
within the controller node.
Inter Scan Delay (ms)
The Inter Scan Delay defines the scan rate, in terms of a minimum delay between accesses in milliseconds.
For example, if the delay is 100, the point group will not be scanned until 100 milliseconds have elapsed since
the last time it was scanned.
Register Type
For Float Point Groups only, this entry selects the source of the data. Select “Input Register” for MODBUS
Input Register or “Holding Register” for MODBUS Holding Register output data. A master port cannot have an
output group of type “Input Register”.
