Using EEPROMs for Program Storage

SIMATIC 545/555/575 System Manual

EEPROMS are portable if, and only if, they meet the following criteria:

• The firmware of the CPU on which the EEPROM was created is

compatible with the firmware of the destination CPU.

EEPROMs created with firmware from Release 1.x through Release 3.x

are compatible forward and backward. However, Release 4.0 is not

backward-compatible; you can use EEPROMs created under earlier

firmware on a Release 4.0 CPU, but you cannot take an EEPROM

created under Release 4.0 and transfer it to a CPU with firmware from

Release 1.x through Release 3.x.

• The EEPROM program was created on a CPU that had a memory

configuration smaller than or equal to the memory available on the

destination CPU.

• If the EEPROM program was created on a CPU that had a

PROFIBUS-DP I/O configuration, the destination CPU must have the

hardware to support such a configuration.

• If the EEPROM program was created on a CPU that had a Series 505

remote I/O configuration, the destination CPU must have the hardware

to support such a configuration (545–1103 CPUs do not support the

Series 505 remote I/O channel).

If you install an EEPROM, the CPU allows you to save your current

program without using a separate EEPROM programming device. The

program can be downloaded directly from RAM to the EEPROM by using

TISOFT auxiliary function 84 or the corresponding function in SoftShop

(select the menu command PLC Utilities → PLC Operations). See

Section 7.2 for instructions on installing an EEPROM chip. See Section 7.3

for instructions on storing a program using an EEPROM.

If your operating program does not change, you can store it permanently on

an EPROM. You can use an EPROM copier to copy your program from an

EEPROM to an EPROM. (The EPROM cannot be programmed in the CPU.)

This is a cost-effective method for creating duplicate copies if you have

additional CPUs running the same program.
