Adoption of block number at sub program call (P-CHAN-00150)

In default case at sub program call the internal value of the last evaluated block number is set to zero.

The read access via the variable V.G.SATZ_NR at the beginning of a sub program delivers the value 0.

If the parameter "remain_block_number_sub_prog_call" is enabled, at sub program call the internal value of the last evaluated block number from the superior (main) program is unchanged.

The read access via the variable V.G.SATZ_NR at the beginning of a sub program delivers a value > 0 (in condition that block numbers are programmed).

Programming example

With disabled "remain_block_number_sub_prog_call" 0

: 
N1000 X100 Y200 Z300 
N1010 LL SUB1.NC 
-> V.G.SATZ_NR access on the beginning of SUB1.NC delivers 0

With enabled "remain_block_number_sub_prog_call" 1

: 
N1000 X100 Y200 Z300 
N1010 LL SUB1.NC 
-> V.G.SATZ_NR access on the beginning of SUB1.NC delivers 1010
