MMS and Your Coprocessor
3-10
Address:
MMS Data Type:
C5:4.CD
BOOLEAN
C5:1.CU
BOOLEAN
C5:0.ACC
INTEGER
C5:13.PRE
INTEGER
C5:0.DN,4
ARRAY of 4 BOOLEANS (This example specifies 4 done bit members of
COUNTERS 0 to 3. This also applies to the other BOOLEAN members.)
C5:0.ACC,50
ARRAY of 50 INTEGERS (This example specifies 50 accumulator members of
COUNTERS 0 to 49. This also applies to PRE member.)
See the section titled Additional Information on Using Data Types, later in
this chapter, and Appendix A of this manual for more information on
mapping MMS data types onto PLC–5 data files.
Input Image (I) Mappings
The table that follows provides sample mappings of input image data
types, where:
I:000/x,n is a bit–string of length n starting at bit x (octal) of the specified
word.
Important: Note that addressing in the Input Image Mapping is in octal.
This does not pertain to the ‘‘size” information. For example, ‘‘I:3/5,10”
specifies a bit string of length 10 (vs. length 8).
Address:
MMS Data Type:
I:000
BIT STRING (16 bits)
I:001,25
BIT STRING (25 bits)
I:000/10
BOOLEAN
I:000/3,5
BIT STRING (5 bits)
See the section titled Additional Information on Using Data Types and
Appendix A of this manual for more information on mapping MMS data
types onto PLC–5 data files.
