Описание:
1. OB - program blocks called by operating system. pre-defined local variables
OB1 - main block (cyclic program sweep)
OB100 - startup (called ONCE after PLC reboot)
2. FB - functions with STAT (memory) functionality. each call requires a instance data block which holds function private data between calls (for example counters, edge bits, etc.)
3. FC - functions without memory
4. DB - data blocks - they hold data organized in structures, send/receive buffers, etc.
