COM 265 Services and File Functions
11.1.4 Reading an IP 265 User Program from a Memory Submodule
Once you have stored an IP 265 user program in an E(E)PROM, you can display it on the
programmer screen any time you wish.
For this purpose, COM 265 provides a special service function for reading the data stored on
E(E)PROM into the programmer's program memory. Subsequent selection of the "Editor" form will
screen the control system flowchart for that IP 265 user program.
Note
The STEP 5 package "EPROM/EEPROM" cannot be used to read an IP 265 user
program from an E(E)PROM memory submodule.
Note
If the IP 265 user program is overwritten on the programmer during loading, operands
and segment comments are lost.
Prerequisites for reading the memory submodule
• An E(E)PROM submodule containing the IP 265 user program to be read must be plugged into
the programmer.
