Sending Fins Commands | Omron CJ1W-DRM21, CS1W-DRM21 instruction

Using FINS Message Communications

Section 6-3

Note 1. Indicates a Unit as shown in the following table.

Unit	Setting

CPU Unit	00

User program in FA computer	01

CPU Bus Unit	$10 to $1F: Unit numbers 0 to 15
	$FE: The local Unit

2.Values of $00 to $3E indicate nodes 0 to 63.

3.Designates the length of time in (0.1-s units) that the PC retries transmis- sion when bit 15 of C+3 is OFF and no response is received. The default value is $0000, which indicates 2 seconds. If baud rate is slow and the re- sponse monitoring time is short, an error may occur.

6-3-4 Sending FINS Commands

DELIVER COMMAND: CMND(490)

Description	CMND(490) can be used in the user program of the CS/CJ-series CPU Unit to
	send FINS commands to read/write I/O memory, read status data, change the
	operating mode, and perform other functions at other nodes.
	CMND(490) transmits the command beginning at word S to the designated
	Unit at the destination node address in the designated network, and receives
	the response beginning at word D.
