Yamaha Yamaha Robot Controller CC-Link Unit, RCX Series owner manual

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.

n 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.

n NOTE

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

4.1Emulated serialization setting on parallel DIO

The relation of the parallel port and serial port that can be connected is shown below.

Input device such as sensor			Output device such as valve
DI port	→ SO port		DO port	← SI port
DI2()		SO2()	DO2()		SI2()
DI3()		SO3()	DO3()		SI3()
DI4()		SO4()	DO4()		SI4()
DI5()		SO5()	DO5()		SI5()

[Operation]
1. Press the F 3			(SIO) key in “SYSTEM > OPTION” mode.
	SYSTEM>OPTION>SIO					V8.01
		1.Direct SI2() -> DO2()			NO
		2.Direct SI3() -> DO3()			NO
		3.Direct SI4() -> DO4()			NO
		4.Direct SI5() -> DO5()			NO
		5.Direct SO2() <- DI2()			NO
		EDIT		JUMP

Valid keys and submenu functions in this mode are as follows.

Valid keys	Menu	Function
Cursor (↑/↓) keys		Selects SIO parameters.
F1	EDIT	Sets SIO parameters.
F2	JUMP	Jumps to specified SIO parameter.
