Data link DL9 (master station) function
11
[3] Data memory area
The data link area and communication monitor flags are allocated in the JW-32CUM1 (control section)
data memory for the data link DL9 (master station) function.
(1) Data link area
The combination of the total number of link bytes and the number of slave stations is used to set the
number of link bytes and the link area for one station as follows.
Upper line: Number of sending bytes Lower line: Number of receiving bytes
- When connecting a slave station other than a JW-21CM (such as JW-10CM), the number of sending
and receiving bytes will decrease to 64 bytes or less. Therefore, settings marked with an asterisk (*)
in the table above cannot be used.
- Specify the total number of link bytes using SW3, and the number of slave stations using switch
SW4, on the JW-32CUM1.
When the JW-32CUM1 is a master station, the link area for slave stations will be determined by number
of link bytes per station.
