This is the format for 99% of the dwgs that make up the PLC Parametric Build.


1 - either (H)orizontal or (V)ertical

2 - P for PLC

3 - denotes the Style of PLC; 1,2,3,4,5...

From here it get a little tricky :0
For the rest of the positions, a dash (-) is used as a place holder
i.e., HP1--WLR.dwg

Based on this chart, this drawing would be Horizontal, PLC,
Style 1, , ,Wire comes from the right, Includes Module Info,
Terminal point located on the right.

4 - w-Wire comes from the left
D-Descriptions are on the left

5 - A-Input Address
w-Wire comes from the left(Used if D is in position 4)

6 - w-Wire comes from the right
A-Output Address

7 - D-Descriptions are on the right
L-Includes Module info: First point on the PLC Block.
w-Wire comes from the right(Used if D is in position 4)

8 - L-Includes Module info(Used if D is in position 7)
R-Terminal is located on left
Q-Terminal is located on right
O-Normally Open (NO) Output contact
C-Normally Closed (NC) Output contact

This makes up the bulk of the PLC I/O dwgs. There are a few special ones, but they are pretty unique. I hope this helps.
