The command configuration to read these 7 floats would be setup as follows.
An array of 7 floats will need to be configured within the ControlLogix processor
as shown.
And the following COP statement will copy the data from
MCM.DATA.ReadData[0]-[13] into the array MCM_Float_Data[0]-[6].
The "Length" parameter is set to the number of Floating Point values that must
be copied from the MCM.DATA.ReadData array.
4.4.3 Write Floats to Slave Device
To issue a Write command to Floating Point addresses, the following
configuration can be used. Below is the Modbus Map for the slave device.
Value Description Type
40261 KW Demand (power) Float. upper 16 bits
40263 VAR Reactive Power Float. upper 16 bits
40265 VA Apparent Power Float. upper 16 bits
40267 Power Factor Float. upper 16 bits
40269 VOLTS Voltage, line to line Float. upper 16 bits
40271 VOLTS Voltage, line to neutral Float. upper 16 bits
40273 AMPS Current Float. upper 16 bits
A COP statement must be used to copy the data from floating point data tags
within the ControlLogix processor, into the MCM.DATA.WriteData array used by
the MVI56-MCM module. Below is an example.
