USEFUL REGISTERS
All MC² applications contains a numbered table of parameters, called registers. They are useful
in a SuperBridge environment for monitoring and control purposes. In the following sections, the
content of the registers for the different applications are listed, along with the property word. The
property word describes access rules, decimal places and scaling of the registers.
The property word has the following layout:
Bit 15..14 Internal storage format, according to the following table:
Bit 15 Bit 14 Storage format
0 0 long (32 bit integer)
0 1 char (8 bit integer)
1 0 int (16 bit integer)
1 1 float (32 bit IEEE floating point)
Bit 13..10 Not used
Bit 9 Set if the register is initialized to zero at controller cold start.
Bit 8 Set if the register is included in the register checksum, that is, is safely retained
when the controller is powered down.
Bit 7..6 At least one of the bits are set if the register is scaled. SuperBrigde will unscale
the register and convert it into a float.
Bit 5..4 Access mask. 00: Read and write permitted. 01: Read permitted. Write permitted
if dip switch 1 is open on the MC² display board, or the ‘Extended Access’ logical
input is ON in the MC³. 10: Read access only. 11: No access.
Bit 3..0 Decimal place codes.
0..4: 0..4 decimal places, respectively.
5..9 according to the values in registers 005..009, respectively, with the
exception of models 20.00.K and 22.00, where the number of decimal places for
code 009 is found in register 170, and 30.00.D, where the number of decimal
places for code 009 is found in register 134.
