Testing and Simulation with COM 265
• Status information
A text line containing the following status messages is displayed beneath the parameter list:
- Operational status of the IP 265 (STOP, RUN)
- Load status of the IP 265 (loaded, not loaded)
- Type of memory submodule plugged into the IP 265 (EPROM or EEPROM)
• IP 265 capacity utilization
The load on the IP 265's program capacity, in percent.
The parameter values and the status info are updated cyclically. Updating is much slower than
IP 265-internal processing (IP 265 clock pulse), i.e. high-speed signal changes cannot be followed on
the monitor screen.
Possible user actions
You can start or stop program scanning easily via function keys <F1> and <F2>.
You can also manipulate the actual values for bit and word input parameters:
Changing bit parameters:
Move the cursor to the bit input parameter.
Press <F3>.
This changes the signal state from "0" to "1" or vice versa.
Changing word input parameters:
Move the cursor to the word input parameter.
Press <F3>.
An input field for the actual value is displayed on the monitor screen
Enter the new actual value and store your entry in the parameter list with <
Note
Since the CPU and COM 265 (programmer) both access the IP 265 via the same
address space, the CPU user program may, under certain circumstances, overwrite
COM 265 data in the PIQ.
Error display
COM 265 displays textual error messages in on-line mode (e.g. "Wirebreak"). Error texts are
displayed in a Help window.
