Item Meaning
PC run
(PC Run) Displays the operating status of PC on the network as
follows:
When user program is not running on PC: No display
When user program is running on PC: YES
YES will be always displayed for nodes with a Controller
Link Support Board.
PC error
(PC err) Displays error status of each PC on the network as follows:
When the PC is operating normally or is not participating in
the data link: No display
When the PC has a fatal or nonfatal error: YES
Communications
error
(Comm err)
Displays the communications status of each node on the
network as follows:
When the node is communicating normally: No display
When the node has caused a cyclic communications error
or is not participating in the network: YES
Data link join
(DtLnk join) Displays the data link participation status of each node on
the network as follows:
When the node is not participating in the data link due to
data link table error or other errors: No display
When the node is participating in the data link: YES
Offset error
(offset err) Displays offset error status in the data link table for node
communications within the network as follows:
When there is no offset error: No display
When there is an offset error: YES
An offset error occurs when the offset value is greater than
the number of send words.
Area short
(Area short) Displays area shortage status in the data link tables for
node communications within the network as follows:
When the area is sufficient: No display
When the area is short: YES
When the data link is inactive: No display.
A short area occurs when the receive area is smaller than
the amount of send data and not all of the send data can be
received. It is not a fatal error. If the receive area
intentionally receives only part of the send data, it can be
used without having to make any changes.
Area remaining
(Area remain) Displays remaining area in the data link table for node
communications within the network as follows:
When the area does not remain empty: No display
When words in the area remain empty: YES
Remaining area occurs when the receive area is larger
than the amount of send data and extra space remains
unfilled after reception. The remaining space will be cleared
with 0s. This is not a serious error. If the receive area
intentionally provides extra space, it can be used without
having to make any changes.
