The values written in BTW words 5–11 specify the parameter read
from or written to the Milltronics device. The parameter is written
repeatedly until a 0 is written to word 11.
This would override any keypad entry for the value specified by
BTW words 5–10 while BTW word 11 is set to 1.
BTW Word 5: Parameter, SPA
Specifies the parameter number.
BTW Word 6: Point, SPA
Specifies the point number for the parameter specified by BTW word 5.
BTW Word 7: Index, SPA
Specifies the index for the parameter specified by BTW word 5. This word is ignored for
parameters which don’t use multiple values.
Some specific Milltronics device parameters use indices to address the multiple values
stored within the single parameter.
For example, parameters P054 level breakpoints and P055 breakpoint volumes use the
index to specify which breakpoint to read. High-level-language programmers might think
of this index as an array index.
BTW Word 8: Value, SPA
This word contains the value to be written to the parameter specified by BTW words
5–7, if BTW word 11 is set to 1. If BTW word 11 is set 0, this word is ignored. The
format of this word is specified by BTW words 9–10.
BTW Word 9: Decimal, SPA
This word specifies the number of decimal places for the value in BTW word 8, and also
for the parameter value returned in BTR word 38.
e.g.:
given:
BTW word 8 = 5,213
BTW word 9 = 1
BTW word 10 = 0
BTW word 11 = 1
then:
the value is interpreted as 521.3 units and stored in the
Milltronics device.
