Graco 332564B important safety instructions Write Fluid Control Mode, Read User ID

Operation Using a Programmable Logic Controller (PLC)

Write Fluid Control Mode

The Write Fluid Control Mode command allows users to remotely change Fluid Control between ‘Flow’ and ‘Pressure’. See System Screen 5, page 71, for more details on Fluid Control mode. The return registers will echo the arguments received.

NOTE: The Fluid Control mode should be changed only when the system is in Standby or when the pumps are powered off. Do not change Fluid Control modes during a mix operation.

Example: Change to Flow Control mode.

Argument 0	Fluid Control Mode	uint32	NONE	0 = Flow Mode	0 = Flow
					1 = Pressure
Acknowledge	Command Acknowledged	uint32	NONE	2 = ACK	0	- 4
Return 0	Fluid Control Mode	uint32	NONE	0	0 = Flow
					1 = Pressure

Read User ID

The Read User ID command reads back the current User ID. See Usage Screen, page 64, for more details on Job Log and User ID. The User ID can be up to ten ASCII characters in length and is packaged as three little endian segments of ASCII characters. No arguments are required.

Example: Read User ID that is currently “John Doe”.
