B. MODBUS Register Reference
I/O Point Analog Values
40001-40100 (double registers, 50 points, 32-bit IEEE 754 floats, most
significant word in first register) or (double registers, 50 points, 16-bit
fixed point value in first register, 0 in second register)
Low Alarm Limits
40101-40200 (double registers, 50 points, 32-bit IEEE 754 floats, most
significant word in first register) or (double registers, 50 points, 16-bit
fixed point value in first register, 0 in second register)
High Alarm Limits
40201-40300 (double registers, 50 points, 32-bit IEEE 754 floats, most
significant word in first register) or (double registers, 50 points, 16-bit
fixed point value in first register, 0 in second register)
Alarm Registers
40301-40400 (double registers, 50 points)
AC Fail Register
40401 (one register):
0x00: AC power on, no previous failure since last flag clear
0x03: AC power off
0x01: AC power is on, but a failure was recorded
Write 0 to clear the flag, 1 to set. Flag is updated continuously.
Interrupter Settings
40501-40516 (single registers):
40501: Cycle Time, milliseconds
40502: Off Time, milliseconds
40503: Duration, minutes
40504: UTC Offset, milliseconds
40505: Relay Open Dwell, milliseconds
40506: Relay Close Dwell, milliseconds
40507: Sync To AC Line, 1=yes, 0=no
40508: Relay On First, 1=yes, 0=no
40509: RelayType, 1=NC, 0=NO
40510: Sched Year, 4 digit year
40511: Sched Month, 1-12
40512: Sched Day, 1-31
40513: Sched Hour, 0-23
40514: Sched Minute, 0-59
40515: Sched Enable, 1=enable, 0=disable
40516: Rectifier State, 0=off, 1=on, 2=cycling
40517: Daily Repeat, 0-65535 days
Realtime Clock
40601: Year (4-digit)
40602: Month, 1-12
40603: Day, 1-31
40604: Hour, 0-23
40605: Minute, 0-59
40606: Second, 0-59
This register block must be read and written as an entire block. A read
of the Year register latches the entire time into a temporary variable
block. A read of the remaining registers reads from the temporary
variable block.
Similarly, a write to the block writes into a temporary variable block
until the Second register is written. At that point the real time clock is
updated with the values from the temporary variable block.
