Bit memory is an area of memory that is accessible to the user program by
means of certain operations. Bit memory is intended to store frequently
used working data.
You may access the following types of data:
- individual
bits
- bytes
- words
- double
words
With your program you may load a time cell with a value between 10ms and
9990s. As soon as the user program executes a start operation the value of
this timer is decremented by the interval that you have specified until it
reaches zero.
You may load counter cells with an initial value (max. 999) and increment
or decrement this when required.
A data block contains constants or variables in form of bytes, words or
double words. You may always access the current data block by means of
operands.
