Working with SIMATIC S5 Memory Submodules

Working with
You can read and program SIMATIC S5 EPROMs and EEPROMs via the
SIMATIC S5
48-pin S5 EPROM and EEPROM programming port. You will find details on
EPROMs and
how to use the programming software in the STEP 5 Manual.
EEPROMs
Figure 3-6
Proceed as follows when working with the S5 EPROM and EEPROM
programming ports:
1. Switch on your PG 740. Start the function "EPROM management" in
2. Start the "EPROM" function in your STEP 5 software (from Version
3. Plug the S5 EPROM or EEPROM into the 28-pin programming port.
4. Read, program or erase (EEPROMs only) your S5 memory submodule
5. Remove the S5 EEPROM
6. Terminate the EPROM programming package of your STEP 5 software.
Caution
!
Risk of damage to EPROMs or EEPROMs!
If you plug the EPROM or EEPROM in or take it out while its processing
software is running, there is a danger that it will be damaged.
You must not take out the S5 EPROM or EEPROM while the LED showing
that the EPROM or EEPROM is being read etc. is lit. You cannot work
simultaneously with S5 EPROMs or EEPROMs and memory cards.
Before plugging in or taking out S5 EPROMs or EEPROMs, you must
discharge the electrostatic charge of your body by briefly touching a
grounded object (ESD guideline).
Note
In order to be able to program the SIMATIC S5 EPROM or EEPROM,
"Programming Interface" must be set to "Enabled" in the SETUP program in
submenu "PG 740 Hardware Option".
