Epoch High
This is the date and time data for the GridBee. The format is the same as that
of the “Unix epoch”, (Epoch High * 65536 + Epoch Low),
where the value is the
number of seconds since 00:00:00 UTC on January 1, 1970. This value is set
by the GPS hardware in the GridBee controller.
Querying register 5 and testing the response against the previous value is a
good way to monitor the communication link between the modbus master and
the slave GridBee controller.

Visual Status
Indicator
This value gives an indication of the GridBee controller health blink indicator.
During normal operation the following values will appear:
4 = (4 Blink Red = Healthy Operation)
Any other indication requires attention:
3 = (3 Blink Red = Motor Controller Communication Error)
10
Motor Speed
The unit for this value is RPM in hundredths. To obtain RPM, divide the value
by 100.
11
Motor Direction
The value of 0 indicates that the motor will be stopped, the value of 1
represents movement in the forward direction, whereas the value of 3 indicates
reverse movement. Viewed from behind or above the motor clockwise motion
is “forward”.
12
Motor Current
The unit for this value is milliamps.
