******************************************************
W A R N I N G
Particular locations have been set up for writing information to an
ADDvantage-32 PLUS. 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 PLUS 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 FLASH memory which has a limited number
of write cycles. Although writing to the FLASH can occur
thousands of times, it is not recommended.
******************************************************
Table 9-1 contains the data files (tables) available in the ADDvantage-32 PLUS. 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.
