Remarks
- When setting an option module (such as the JW-22CM) is installed on the JW-34KBM basic rack
panel (and the JW-32CUM1 is installed on the same rack panel), be careful that the data memory
area does not overlap the DeviceNet area previously assigned.
[3] Setting the data memory area and system memory
The settings for the data memory area and system memory on the JW-32CUM1 (control section) are
shown below.
O: Valid setting —: Invalid setting
Data table allocation system
- In the data table allocation column, "fixed" refers to the fixed allocation scheme and "free" refers to
the free allocation scheme.
1. "Fixed allocation" means that each table area is allocated in advance.
2. "Free allocation" means that you must specify the first address of each table that is required in
system memory.
- To select "fixed" or "free," set bit 7 ON or OFF in the specified system memory location (4th byte) of
each table. - See pages 8-13 and 8-14.
