Communication

4. Direct connection by emulated serialization on parallel DIO

The master station PLC can exchange bit information data with the parallel port on the
robot controller’s parallel I/O unit regardless of the robot program. By using this func-
tion, I/O devices such as a sensor or relay can be used like a device connected to CC-Link.

Function

NOTE

When the port specified by SIO is
identical with the port used by the
program, the output results might be
inaccurate.

NOTE

When the directly connected and set
output port is used with the program,
the bit information may not become the
intended value. Do not use the directly
connected and set output port with the
program.
