Memory Areas
DM Area: CS/CJ CPU Bus Unit Area
The CS/CJ CPU Bus Unit Area (DM Area) is allocated to CS/CJ CPU Bus Units according to the unit numbers
assigned to them, as shown below. Each Unit is allocated 100 words, of which 10 words are used. In the Con-
troller Link Unit this area is called the DM Area.

Polling node/polled node bit
0: Polling node
1: Polled node
Note 1: Initializes the network parameters registered in the CS1 CPU Bus Unit PLC Setup Area on the CPU Unit
and clears the data link tables.
2: Be sure to set the bit in the DM Area's (CPU Bus Unit Area's) software switches (D30000 + 100
number) described as "always set to 0" to 0. Not doing so may result in the data link not starting properly.
If a data link is started with bit 7 of the software switches set to 1, the data link status will be stored in a
format different to the one described in this manual (when using CS-series or CJ-series Controller Link Units).
