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 (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 oper-
and. Set
Data
to 1N + 1 because the RUN command data uses four bytes each from D + 3, D + 6, and D +
9.
Set
Edit Length
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.
