I have questions regarding the Series 90-30 PLC status bits:
1. %SC14 and %SC15 - They are labeled hardware fault and software fault respectively, but what exactly triggers them?
2. The above mentioned faults only clear when the fault tables have no entries. How can I provide a method for resetting fault tables for the user through the HMI? It seems that the only method is to use Proficy, which my customer does not have.
3. %SA11, Low battery fault, will not clear even after installing a new battery. Has anyone ever encountered this?
