If not, the data links will not start.
Item
Set the number of words in BCD between 0 and 1,000.
The total number of send words for master node of area 1
and area 2 must not exceed 1,000.
Set to 0 when area 1 is not to be used or when the master
node will transmit no data.
Set the number of words in BCD between 0 and 1,000.
The total number of send words per slave node of area 1
and area 2 must not exceed 1,000.
Set to 0 when area 1 is not to be used or when the slave
node will transmit no data.
Set the word address in BCD.
CIO Area: 0000 to 6143
LR Area: LR 000 to LR 199 (CIO 1000 to CIO 1199) (See
note.)
DM Area: DM 00000 to DM 32767
EM Area: Banks 0 to 12: EM 00000 to EM 32767
Note: When a word between LR 000 and LR 199 is spec-
ified, the data link area will be allocated between words
CIO 1000 and CIO 1199 in the CIO Area.
Set the area type of area 2 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
When area 2 is not used: 00 Hex
Set the number of words in BCD between 0 and 1,000.
The total number of send words per master node of area
1 and area 2 must not exceed 1,000.
Set to 0 when area 2 is not to be used, or when the mas-
ter node will transmit no data.
Set the number of words in BCD between 0 and 1,000.
The total number of send words per slave node of area 1
and area 2 must not exceed 1,000.
Set to 0 when area 2 is not to be used, or when the slave
node will transmit no data.
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.
