Prior to use, the programmer sets N11:2 to the total number of data blocks which will be entered into file N10 (not including the Counter Control
Block), adds one rung for each configuration block (including the Counter Control Block), and initializes the data blocks in file N10. Ten integer data
blocks are used (instead of eight) to simplify the display in data windows. Note: The Counter Control Block rung differs from the other rungs
because the Counter Control Block does not require hand-shaking.
The first pass of the program initializes the following values:
1. The HSCE2 initialization done bit (B3/0) is unlatched.
2. The HSCE2 error bit (B3/1) is cleared.
If the HSCE2 initialization is not done, and the HSCE2 has not errored, call the HSCE2 initialization routine.
