24: REMOTE I/O SYSTEM

OPENNET CONTROLLER USER’S MANUAL 24-13

Function Area Setting for Remote I/O Master Station

Normally, the remote I/O communication does not require the Function Area Settings. The CPU module at the remote I/O

master station recognizes the remote I/O slave stations automatically at power-up and exchanges I/O data through the link

registers allocated to each slave station (node).

You can also conﬁgure the remote I/O system setup in the master module. When the quantity of nodes is speciﬁed, the

CPU communicates with slave stations as many as speciﬁed in the Function Area Settings. If the conﬁguration in the Func-

tion Area Settings differs from the actual remote I/O system setup, the CPU does not start the remote I/O communication.

For example, when any of the slave stations are removed or added or the INTERBUS cable is disconnected, the remote

I/O communication is halted. To conﬁgure the remote I/O master module, make settings in the Function Area Settings for

the user program.

Since these settings relate to the user program, the user program must be downloaded to the OpenNet Controller after

changing any of these settings.
