for message communications data.
Create algorithm of each POU and register local variables of each POU.
Register the Unit in the Unit Configuration on the CPU/Expansion Racks
screen in Configuration and Setup.
At this time, set both the device name and the unit number of the unit to be
registered.
Allocate device variables for CJ-series Unit to I/O port.
Allocate on the I/O Map View window.
You can use one of the following three methods to allocate.
1. Select and allocate existing variables.
2. Input a new variable name.
3. Automatically create with "Device variable creation".
Create the Unit settings by using the [Edit Special Unit Settings].
(When the program is transferred, items set here will be reflected
in the device variable for CJ-series Unit.)
Set the hardware switch on the front panel.
Set the same unit number as in the Unit Configuration settings.
Initial settings for slaves
Set by referring to the Manual for Slaves.
Transfer user programs, Unit Configuration and Setup, and variable
information.
