The second rung of a small program:
| I0.1 I0.0 v50.0
|--][------][------( )
| |
| v50.0 |
|--][----
I0.1 is a reset P/B, I0.0 is the e-stop circuit.
If the main switch is turned off with v50.0 latched, I find it is still latched on power resumption. I had to use the first scan bit to kill it on power-up.
Is this peculiar to this particular PLC, or do all PLC's act in this way?
