The length is set in the length box. Insert the length by using the Insert icon. The
length is the number of bytes of the succeeding data (R(3N + 3), 4). The length is
automatically set by the CX-Protocol.
(R(3N+3), 4)
The Inverter's actual data to be sent. This example selects Variable and Read R()
and sets the operand. Set Data to 3N + 3 because the RUN command data uses four
