5.6.4 SLC Processor Specifics
This section contains information specific to the SLC processor based family
when used with the DF1 command set. The SLC processor commands support a
file type field entered as a single character to denote the data table to interface
with in the command. The following table defines the relationship of the file types
accepted by the module and the SLC file types:
SLC File Types
File Type File Type Command Code Description
S 83 Status
B 66 Bit
T 84 Timer
C 67 Counter
R 82 Control
N 78 Integer
F 70 Floating-point
Z 90 String
A 65 ASCII
The File Type Command Code is the ASCII character code value of the File Type
letter. This is the value to enter into the "File Type" parameter of the DF1
Command configurations in the data tables in the ladder logic.
Additionally, the SLC specific functions (502, 510 and 511) support a sub-
element field. This field selects a sub-element field in a complex data table. For
example, to obtain the current accumulated value for a counter or timer, the sub-
element field should be set to 2.
