LAST_DATA_BLOCK
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. The first pass of the program initializes the
following values:
The first pass of the program initializes the following values:
1. The HSCE2 initialization done bit (B3/0) is cleared.
2. The HSCE2 error bit (B3/1) is cleared.
