Setting item
Setting range
Nodes
Optical Ring: 1 to 62 (1 to 32 when optical and optical ring connections are combined.)
Wired: 1 to 32
Set the addresses of the refresh nodes.
First data link
status word
The first data link status word is fixed; the setting cannot be changed. Set to –.
Area 1
Data link
start word
Set the start word within the FinsGateway event memory setting range. The defaults are
CIO 0 to CIO 32767 and DM 0 to DM 32767.
The same area cannot be set for both area 1 and area 2. Set different areas.
Number of
words
Remote nodes: 0 to the number of source words
Set the number of words to be received.
Local node:
0 to 1,000
Set the number of words to be transmitted.
The total number of words in area 1 and area 2 in each node must not exceed 1,000.
The numbers of words in both area 1 and area 2 in each node must not be set to 0.
Offset
Remote nodes: 0 to one less than number of source words
Set the offset for the data to be received.
Local node:
Cannot be set.
This setting is not required if an offset is not used.
Area 2
Data link
start word
Set the start word within the FinsGateway event memory setting range. The defaults are
CIO 0 to CIO 32767 and DM 0 to DM 32767.
The same area cannot be set for both area 1 and area 2. Set different areas.
Number of
words
Remote nodes: 0 to the number of source words
Set the number of words to be received.
Local node:
0 to 1,000
Set the number of words to be transmitted.
The total number of words in area 1 and area 2 in each node must not exceed 1,000.
The numbers of words in both area 1 and area 2 in each node must not be set to 0.
Offset
Remote nodes: 0 to one less than number of source words
Set the offset for the data to be received.
Local node:
Cannot be set.
This setting is not required if an offset is not used.
Note
1. The maximum number of words for area 1 and area 2 combined must be no
more than 62,000 for optical ring connections and no more than 32,000
words for wired connections or systems that combine optical and optical ring
connections.
2. Data link areas in the Controller Link Support Board are allocated in the
FinsGateway event memory. Refer to the FinsGateway online help for in-
formation on the area types and sizes in event memory.
3. Be sure to delete data link tables for all nodes not participating in the data
links.
4. When using the Controller Link Support Software, set the “PC type” to “oth-
ers.”
