For the temperatures, 0 represents -50 degrees Fahrenheit, 4095 represents
250 degrees. For the pressures, 0 represents 0 psi and 4095 represents 200 psi.
HR40010 bit 0 represents the running state for Unit 1, bits 1 and 2 represent the
same for Units 2 and 3. Bits 3, 4, and 5 represent an alarm condition for each of the
three units.
In addition, coils C10001, C10002, and C10003 are used to start/stop Units 1, 2, and
3 respectively.
This interface will operate at 9600 baud with no parity and eight data bits. The
controller is at Modbus unit address 5.
