Detailed StarPac ll Register Map
This reference will aid you in understanding the configuration of the StarPac ll register table. Registers are
described and notes are provided that give the range and more detailed information.
The StarPac ll register table consists of three different types of information: integers, IEEE floating point
numbers and strings. These types can have a read only (RO) access attribute or a read/write (RW) access
attribute. You can only read RO registers. Writing to a RO register will generate an exception error. You
can both read and write to RW registers.
The register numbering is as follows: a 30000 base indicates RO integers, a 40000 base indicates RW
integers, a 70000 base indicates floating point numbers, and a 50000 base indicates strings. For example,
a register number of 30003 indicates a RO integer.
Two contiguous integer registers make up a floating point register. You will get an exception response if
you try to access into the middle of a floating point register.
Registers making up bit fields follow the MSB/LSB (Most Significant Byte/Least Significant Byte) format.
Internally, Valtek calculates the StarPac ll variable numbers by taking the module of the register number
and 10,000 and subtracting 1. For example, register number 30001 would become variable number 0.
