Programming the EEPROM Memory By giving the "F1 PROGRAM" command from the EEPROM menu of the programming device, the processor module is abandoned in order to copy the application program from EE32 RAM to the EEPROM. During the EEPROM programming, the programming LED is lit. Programming the EEPROM can also be done when an application program is still running. After the programming procedure is finished, the write protect switch (WE/WP) is to be set to WP (Write Protected). This ensures that the program will not be accidentally overwritten from EEPROM memory. EEPROM memory is not deleted, it is simply overwrit- ten with a new program. Uninterrupted Application Program Transferal An application program can be downloaded into the RAM of the EE32 with the programming command "XFER" and without any influence on the program running in the EEPROM. The program in RAM and the one in the EEPROM can be switched between with a command on the programming device. The switch is made synchronous to the program cycle. Loading Application Programs from the EE32 Module Application programs can be loaded back to the programming device from the EE32 module. This can also be done with the application program running. A program which has been reloaded from the EE32 module can still be run but it no longer has any comments, ladder diagram pictures or symbols. Power-On Behavior A finished program must be stored in the EEPROM when the PLC system is powered on with CPUs. If a complete runnable program is not stored in the EEPROM, the status LED lights and the CPU remains in HALT state until a program is transferred from the programming device. 1) The combination of network capable on-line interface module with modem interface and application program memory module is described in section A7 "PLC Programming / On-line Networks and Modem Diagnosis".
