Trouble-Shooting Techniques

As discussed previously, useful information about a problem can often be obtained
using the tools and error reporting facilities built-into the product.
Check Failure LEDs on Hardware
If your controller includes visible failure indicators (LEDs), look at them to see if a
hardware problem has occurred. Instructions for interpreting what the failure
LEDs mean is included in the hardware (CI-3xxx) manual. Some hardware failures
can also be detected via off-line diagnostics. See the 33XX Diagnostics Manual
(document# D4041) for details.
If You Suspect A Problem in an ACCOL Task, Use A Debugger
To examine ACCOL logic, on-line, use ACCOL Workbench in on-line debugging
mode, or for older units, use Taskspy. For information on Workbench, see the
ACCOL Workbench User Manual (document# D4051). For information on Taskspy,
see the Taskspy Manual (document# D4083).
For a Quick Check on Communications, Call Up #TIME Signals
A good way to test whether communications are operating properly with a
1
particular node, is to view its #TIME.nnn. system signals, via DataView . Look at
the #TIME.001. and #TIME.007. signals (which are in units of seconds). The rate at
which these signals change will tell you how fast data is being updated at the PC.
