"Only when the master station PC is a JW model and a JW model special I/O module is used as a slave station"

Enter the data register address

 

 

Station number: OCT (octal), bytes

 

 

 

of the special I/O module

 

 

Rack and slot numbers: HEX (hexadecimal), bytes

 

 

 

 

Number of data bytes: DCM (decimal), bytes

 

(Applied to item on pages

 

 

 

8·31 and 8·35)

 

 

Register top address: OCT (octal), bytes

·Since the special I/O module uses an I/O relay area and a data memory area, you have to enter slave station numbers, rack/slot numbers, the number of data bytes, and the top register addresses of the slave station which contains the special I/O module at parameter address 000600 to 000777(8).

·Use 4 bytes of memory to assign one special I/O module.
