is the number of bytes of the succeeding data (W(1N + 1), 2). The length is automatically
set by the CX-Protocol.
(W(1N + 1), 2)
The Inverter’s actual data is to be sent. This example selects
Variable
and
Read R()
and sets the operand. Set
Data
to 1N + 1 because the RUN command data uses four
bytes each from D + 3, D + 6, and D + 9.
Set
Data Size
to 0N + 2 so that it will be set to two bytes.
7-9-5 Ladder Program
·
Transfer the created protocol to the Communications Board.
·
The following example describes how to control the Inverter with this protocol.
·
Before using this program in your system, be sure to check the word and data memory
allocations and change them if necessary so that there will be no word or data memory
duplication.
·
This program will stop all communications if a communications error or fault occurs. Be
sure to set n151 for communications time-over detection selection to 0 through 2 so
that the system will stop with time-over detection.
