Advanced Control Module (ACM)

W A R N I N G
Particular locations have been set up for
writing information to an ADDvantage-32.
These locations are A***:LOCATION X for analog
values and D***:LOC BIT X for digital values.
It is highly recommended that all information
written to an ADDvantage-32 be written to
these locations. These parameters reside in
regular system memory and can be written to
often. If information is written to
parameters such as C***, it is being written
into the EEPROM memory which has a limited
number of write cycles. Although writing to
the EEPROM can occur thousands of times, it is
not recommended.
***************************************************
Table 9-1 contains the data files (tables) available in the
ADDvantage-32. The items listed in Table 9-1 are defined as
follows:
1.
File Number - Number of the table containing the
data.
2.
Table Name - Name of the table containing the data.
3.
Structure - Number of bytes required for one
element of data in the table.
4.
Data Type - Data format such as:
FP = Floating Point Numbers (Four bytes per data
element)
I = Integer (Two bytes per data element)
LI = Long Integer (Four bytes per data element)
A = ASCII (One byte per data element)
5.
Data Mode - Data in the table is either RO or R/W.
RO = Read Only (Write Protected)
R/W = Read or Write (No Protection)
6.
PAR - Represents the parameter group covered
by the table.
