(PV) when the input Cx(RESET) becomes active. The counter
in backward mode will stop counting when it reaches zero.
The preset value (PV) can be a constant, or the contents of an
area VW, SMW, AI, or TR.
7.6 Mathematic formulas (FM)
The functions of math formulas FM execute mathematical
operations (+, -, *, /, | [OR: logical inclusive or], & [logical AND], ^
[XOR: logical exclusive or], << [ROL: ROtate shift Left], >> [ROR:
ROtate shift Right) between two operators and saves the result in
another memory location. The operators can be numeric
(constants) or refer to the available areas of memory (variables).
7.7 MOV assignments
The function MOV (move) assigns a numeric value (constant) or
the contents of another location (source area) to a specified
location in memory (destination area).
An instruction such as MOV(A=B) copies the contents of the
memory location B to the memory location A.
7.8 BLKMOV multiple assignments
The function BLKMOV (block move) assigns a numerical value or
the value from another (source) block of memory to a destination
block of memory.
An instruction such as BLKMOV(A
i
=B
i
, num. data 8) copies the
contents of memory B
i
into the location of memory A
i
, the contents
of location B
i+1
into the location A
i+1
, ……and the contents of
B
i+7
into the location A
i+7
