Timer2 delays evaluating the write status until the Powermonitor 3000 unit has reset.
This rung evaluates the results of writing the new configuration.
The "Failed" flag asserts if the WriteNew message instruction errors-out, or if the GetStatus instruction errors out twice, or if the write status
indicates bad data in the download table. If there is a bad data indication, verify that word 0 of the download table is the correct Powermonitor 3000
password, that word 1 is a value of 31 (decimal) and that at least one or more words beginning with word 3 are non-zero. Then try toggling "start" again.
Counter1 increments if the GetStatus message errors out. The logic will wait until Timer2 times out and then retry the GetStatus message.
When the operation is complete with no errors, the "Success" flag asserts and the "Start" flag is cleared.
