TRIO LAN Display
Use Restart Bus if the CI560 TRIO MIB submodule does not come up as expected
after a controller reboot or to restart a failed Field Bus Controller.
Use Switch Bus to force a switchover of all blocks using the selected ACTIVE bus
with redundancy AVAILABLE to the other bus.
TRIO Blocks on the Field Bus
Each block on the Field Bus is represented by a row on the TRIO LAN Display. To
select a TRIO Block Display, move the cursor to the row for the block and click.
The block column has either the block number in red or the background in red to
indicate the block has an active diagnostic message. The following information is
displayed for each block:
Block
Templet
184
The first cell in a row contains the block number, 1 to 30, for the
block on the bus. This number is displayed as follows for the
indicated conditions:
Red = diagnostic(s) active
Black = no diagnostics active
On the AC Controller, if this cell has a black
background, you can use the context menu to
get the Switch Bus command (background is
red if diagnostic is active). Using Switch Bus
here switches only those blocks associated with the BSM (a single
stub) providing redundancy is AVAILABLE.You will be asked to
Confirm or Cancel the switch bus request.
Also on the AC Controller, the letter A or B after the number
indicates which bus the block is using. If the block is FAILED, then
a ? replaces the bus letter.
This cell contains either the name of the block templet or NOT
CONFIGURED if no block templet exists.
