Chapter 6 FBD Block Diagram Programming 175
MD (MUL-DIV) function block
There is a maximum of 250 MD (Multiplication and Division) function blocks under FBD mode, and the function is
same as Ladder mode.
Compute formula:
3/2*1 VVVMD
Parameters V1, V2, and V3 can be a constant or other function current value. The output coil will be set to 1 when the
result is overflow or parameter V3 is zero.
Example:
AQ02 = MD01 = AT01*15/100
