COM 265 Services and File Functions
LED indicators
The STOP LED on the module's frontplate flashes at high frequency to indicate that the module is
being loaded over the I/O bus.
Duration of the load procedure
The IP 265 user program is transferred in 1000 data cycles. At an average CPU cycle time of 20 ms,
the load would take approximately 20 s. If an EEPROM has to be overwritten, the load takes
approximately 80 s.
11.1.3 Storing an IP 265 User Program on a Memory Submodule
The IP 265 user program can be programmed direct into a memory submodule plugged into the
programmer. COM 265 provides a special service for this purpose.
Note
The STEP 5 package "EPROM/EEPROM" cannot be used to store an IP 265 user
program on an E(E)PROM memory submodule!
Prerequisites for a successful storage procedure:
• The IP 265 user program to be stored (e.g. "IP265") was selected in COM 265's "Defaults"
form.
• The IP 265 user program (e.g. "IP265") was compiled without error by the COM 265 compiler.
• The programmer is equipped with an EEPROM memory submodule or an empty EPROM
memory submodule.
You will find a list of permissible E(E)PROM memory submodules in Appendix G, "Accessories and
Order Numbers", of the Product Manual.
