ceed 20,000 per node when using Controller Link Units with unit Ver. 1.2
or later, or 12,000 words per node if using pre-Ver. 1.2 Controller Link
Units. The total number of words in data link send and receive areas of a
master node must satisfy the following values. Since the number of master
node words is greatest when 1:N allocation is used, the value can be esti-
mated from the number of master node words.
Item
Set the word address in BCD.
IR or CIO Area: 0 to 6143
LR Area: LR 000 to LR 199 (1000 to 1199) (*)
DM Area: DM 0 to 32767
EM Area: Banks 0 to 12 EM 0 to 32767

Set the area type of area 1 as a hexadecimal number.
IR Area: 80 Hex
LR Area: 86 Hex
DM Area: 82 Hex
EM Area Banks 0 to 7: 90 to 97 Hex
Set the number of words in BCD between 0 and 1,000.
The number of common send words per master node
added to the number of delivery send words per node
must not exceed 1,000.
Set to 0 if common data is not to be sent from a master
node to a slave node.
Set the number of words in BCD between 0 and 1,000.
The number of common send words per master node
added to the number of delivery send words per node
must not exceed 1,000.
Set to 0 if delivery data is not to be sent.
Set in BCD the first word used for storing data link status.
When automatic setup is used, status can be stored in
the IR or CIO Area only. The number of words used to
store status depends on the data link status storage for-
mat specification as below.
