MODBUS Register Map
(cont.)
Notes:
1. Clear Totalizers:
flag from the 8051 to clear totalizers in the
68332 memory.
2. Error Value:
see Chapter 2,
Error Codes and Screen Messages
, in
the
Service Manual
for error codes.
3. Average:
average of channel 1 and channel 2 if both channels out of error,
channel 1 value if channel 2 is in error,
channel 2 value if channel 1 is in error,
zero if both channels in error
4. Average Error Status:
0 = both in error
1 = chan 2 in error
2 = chan 1 in error
3 = both OK
5. Registers for Analog Inputs:
The values for the inputs apply only to special inputs (supply and
return temperature inputs are in other defined registers). The
DF868 can hold only up to 4 special inputs. Input registers for
slots and inputs that are not resident or not programmed as special
will have an output value of 0.
6. MODBUS baud rate:
5 = 2400, 6 = 4800, 7 = 9600, 8=19,200.
7. MODBUS parity:
0 = none, 1 = odd, 2 = even
8. MODBUS stop bits:
1 = 1 stop bit, 2 = 2 stop bits
9.
General:
Registers are written if corresponding functions are actuated by
the user. Registers for unactuated functions are initialized to zero
at startup.
