Chapter 2 The AADvance Safety Controller
Faults in the processor modules are none latching. The controller will recover
automatically and the fault indication will clear once the fault condition has
been removed. Faults in the I/O modules are latched. To clear them a fault
reset signal is sent from the processor module by pressing the Fault Reset
button on the processor module front panel. Field faults are not latched and
will clear as soon as the field fault is repaired.
When the Fault Reset button on each processor module is pressed it attempts
to clear a fault indication immediately, however, the diagnostic systems will
report a serious problem again so quickly there will be no visible change in the
fault status indications.
Remote Fault Reset
Using the Workbench software you can set up a fault reset variable to mimic
pressing the Fault Reset button on the front panel. This feature is provided for
systems located in inaccessible locations. Refer to the AADvance
Configuration Guide Doc No:
ICSTT-RM405 ( ICSTT-RM458 for
Workbench 2.x) for instructions on how to set up the variable.
On-line updates I/O Configuration Changes
The AADvance controller modular design makes it easy to create and change
the I/O configuration. The on-line update facility enables you to make changes
to the I/O configuration after the system is commissioned.
An on-line update can be used for the following changes.
• Expand a system and add new I/O modules, base units and termination
assemblies.
• Change the module type in a simplex or group arrangement.
• Expand a simplex or group arrangement.
• Downgrade a group arrangement.
• Move a module to a different slot.
• Change an application variable.
You only have to plug an additional I/O base unit into the side socket on an
installed I/O base unit. The command busses on the I/O base units do not
need different terminations on the open ends of transmission lines, and the
data response busses and power sources are supplied across all I/O base units.
Termination assemblies are pushed into the I/O base unit for the additional I/
O modules. To put the new modules on-line and make the changes to the
