Program
11.4.1 Logical addressing on startup
The logical addressing of the INTERBUS-S System is activated via the FB 210 func-
tion block. It includes an initialization block (INITIB), two driver blocks (REQ/RES,
CON/IND), an auxiliary block (CIH) and the addressing block (ADDRESS).
11.4.2 Cyclic program OB1
The INTERBUS-S System is started here. The addressing block transmits the logical
address lists for the purpose of checking the interface module.
Following the logical addressing, the application can access the defined module
addresses.
As the message driver (CON/IND) is cyclically accessed, the messages are not disab-
led.
The function of the system can be monitored via the diagnosis register (diagnose-bit/
parameter-register).
The base address set as window 3 on the INTERBUS-S interface unit
is to be used as parameter FEN3 of the FB 60 function block.
