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

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⋅ unit 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).
