5 PLC Interface 10.94
5.1.3 Function blocks (FB, FX)
Note:
1. Make sure that no confusion with the SINUMERIK blocks is possible. The user must not
utilize a SINUMERIK standard block name, nor may he assign a SINUMERIK library
number to his user blocks.
2. In the range of FB 0...FB 199
FX 0...FX 99 SINUMERIK blocks have absolute priority.
If SINUMERIK blocks must be used at a later time that overlap user block numbers, the
user blocks must be given a new number.
3. The SINUMERIK 880 with PLC 135 WB has no basic program written in STEP 5 in the
way the SINUMERIK 850 has. The corresponding functions are implemented in the PLC
operating system.
