Appendix A – Slave Instrument Mapping



The following tables can be used as a reference for retrieving information such as the PV, setpoint, etc
from a slave instrument. The slave instrument information will have a base offset based on the
instrument number that is assigned. The base offset can be determined using the following formula:

Base Offset = (Instrument Number * 100) + 900

For example, the base offset for instrument 1 would be 1000

(1 * 100) + 900, and the base offset for

instrument 7 would be 1600

(7 * 100) + 900. The slave instruments will be split into three sections:

Atmosphere Instruments, Temperature Instruments, and Events Instruments. The layout for each
instrument will be the same:

Controller – The type of controller the slave instrument is – i.e. AC20, Series 9010, etc.

Source Location – The register

in the controller

where the specified value is located.

Note: These

will be added on to the base offset of the instrument (see above section)

. For example, the

source location for %C actual for an AC20 is 11. For instrument 1, the register to find the %C
actual would be 1011

the base offset for instrument 1 is 1000, plus the source location of 11.

Write Register – The register

within the slave instrument

where the value will be written.

Read Scale – Any value read in from an instrument will be divided by this number for display
purposes only.

Write Scale – Any value written to an instrument will be multiplied by this number for display
purposes only.

Description – This will be a brief description of what the value is, i.e. %C actual, Setpoint, etc.
