Using EEPROMs for Program Storage

SIMATIC 545/555/575 System Manual

If an error occurs during the copy process it will be listed on the

programming unit. If an error occurs, perform the following checks:

• Ensure that the EEPROM jumper pin programming enable strap is

installed correctly (on the 545 or 555 CPUs).

• Ensure that an EEPROM, not an EPROM, is installed (on the 545 or

555 CPUs).

• Ensure that all EEPROM pins are properly seated in the socket.

• For CPUs that support both portable and on-board EEPROM, ensure

that the jumper E20 is configured to select your target EEPROM. In

addition, if you select on-board EEPROM for program storage, ensure

that the portable EEPROM is not installed.

Other possible causes for errors include the following:

• The EEPROM may be defective.

• The EEPROM may already have been programmed (and not erased).

Use the TISOFT auxiliary function AUX 84 to erase program data on

the EEPROM.

• The size of your user program that is being stored may exceed the size

of the installed EEPROM.

If you suspect a defective portable EEPROM, power down, remove the

EEPROM, install another EEPROM, power up again and repeat the

programming procedure.
