IO/Outputs/[ROUT]/$HourMeter Registry Key
This dynamically reports the total number of hours that the relay output
has been in the CLOSED state. This value is non-volatile maintaining content
through power loss and until it is specifically reset. It is reported here
in hours to the one-hundredth. The Hour Meter is accurate to the millisecond
and this high resolution value may be read through the JMP Protocol, the
JNIOR Protocol or using the JRMON command.
