IP 265
7.2 Loading
There are two ways of loading the IP 265:
• Loading via the external I/O bus
• Loading from the memory submodule
During both loading procedures, all inputs and outputs of the module are passive. The loading
procedure is indicated by high-speed flashing of the STOP LED on the module front and by the
relevant status acknowledgements in the status word of the module ( Section 4.3.2).
7.2.1 Loading the IP 265 by Means of COM 265 Via the External I/O Bus
Loading via the I/O bus is only possible using COM 265. COM 265 has a special utility: "Loading
IP 265 via I/O bus". After calling the utility, COM 265 handles loading of the program data
independently via the I/O bus.
Some prerequisites must be fulfilled for the loading procedure:
• The program memory of the programmer/PC contains an IP 265 user program generated by
means of COM 265 and compiled into IP 265-relevant data,
• An EEPROM submodule is plugged into the submodule receptacle of the IP 265
or
the submodule receptacle of the IP 265 is empty.
Note
If an EEPROM is plugged into the module, the IP 265 user program is additionally copied
onto this memory submodule.
Note
COM 265 evaluates the memory submodule before transferring the program data into
the IP 265. If an illegal submodule or an EPROM submodule is plugged into the module,
COM 265 outputs an error message.
Operator inputs at the CPU
Since the remote I/O bus is operated via the CPU, user inputs can be made depending on the
operating state of the CPU prior to inputs with COM 265 ( Table 7-1).
User inputs in COM 265
The necessary inputs in COM 265 for initiating the loading procedure are described in Section 11.1.2
"Loading the IP 265 Via the I/O Bus". During the loading procedure, COM 265 coordinates program
scanning automatically on the CPU and the IP 265 ( Table 7-1).
