User-set Remote I/O Allocations Using the CX-Integrator
Additional Information
You can stop remote I/O communications with a specified slave to effectively disconnect the
slave from the network by changing
*_CnctCmd
(Disconnect/Connect Switches) to TRUE. You
can do this when a slave is replaced or to register a slave in the scan list in preparations to con-
nect it to the network at a later time. The Disconnect/Connect Switches, however, are cleared
when the power supply is turned OFF, so the bit must be changed back to TRUE from the user
program after the power turns ON in order for it to remain effective.
Turn ON the communications, slave, and Controller power supplies.
Start the CX-Integrator.
Switch the CPU Unit to PROGRAM mode.
Master remote I/O communications will begin with the scan list enabled.
(Use the software switches or CX-Integrator to start or stop communications.)
1) Create a network configuration online on the CX-Integrator.
2) Enable master communications in the CJ1W-DRM21 properties.
3) Create master device parameters.
Check to see if both the MS and NS indicators are lit green on the Master Unit and all slaves.
Read the network components using the CX-Integrator.
Save the components as a project file using the CX-Integrator.
Note: Turn ON the communications power supply prior to
turning ON the slave power supply. Or the slaves may
not go online.
4) Save the data as a project file.
5) Read the project file, go online, and
download the file to the network devices.
3) Read the project file, go online, and
download the file to the network
devices.
