PROTOCOL-SPECIFIC INFORMATION
inverter’s command register. A value of 0x0002, therefore, means that the run forward bit has been
turned ON.

Similarly, we can see that the second 16-bit word of output data (Interface_Card:O.Data[1]) has
been set to a decimal value of 6000. The default consumed data word configuration word offset 1
references register 2, which is the inverter’s frequency command register. A value of 6000,
therefore, equates to a frequency command of 60.00Hz.
The input data from the inverter shows similar expected results. Values of 0x004B and 6000
corresponding to registers 100 (status register) and 101 (output frequency), respectively, are
consistent with the inverter running at the parameter values commanded by the output tag.
