Restore Factory Default Settings/Flush Memory
Follow these steps to restore the module’s factory default settings.
1. While the SLC processor in Program mode, clear the module
command word 0 and set bit 2 of word 0 for the module to ON
or 1 (starting with bit 0 going from right to left, this is the third
bit).
2. Set bit 0 of word 0 for the module to OFF or 0.
3. On the SLC processor, cycle the keyswitch from Program mode
to Run mode then back to Program mode.
4. When the code E9 is displayed on the Address/Error status
display, the default settings have been restored.
5. Set bit 2 of word 0 for the module to OFF or 0.
6. Cycle power to the 1746 chassis to restore normal operation to
the module.
The module will now have its factory default settings:
•
node 63.
•
125 Kbps.
•
no scanlist.
IMPORTANT
If other bits in the module command word are set, then the
module will generate an error.
IMPORTANT
The ladder logic may set bit 0 of word 0 for the module. If this
happens, then you must disable or delete this rung from the
ladder program.
