These registers indicate the current state of the digital inputs and outputs. These registers may
only be read; writes will be ignored, as this product does not support forcing inputs or outputs.
Because different PLCs label bit numbers differently, the following chart is provided to show the
mapping between the devices:

Plot Time Registers:
The Plot Time interval is configurable on the RMC. This interval indicates the number of control
loops between each sample in a plot. Therefore, if the control loop is 0.976ms (e.g. RMC100-M1),
this value indicates roughly the number of milliseconds between samples. If the control loop is
1.953ms (e.g. RMC100-M4), this indicates half of the number of milliseconds between samples.
These registers may be read or written. When read, they indicate the plot interval of the currently
gathered plot. When written, they set the plot interval the RMC should use for the next plot it will
gather. When the RMC starts the next plot, it copies the requested plot interval into the currently
used plot interval.
