4.4 Saving a Program
You can save the STEP 5 program in the RAM of the PLC. The STEP 5 program includes all valid
OBs, PBs, FBs, SBs and DBs, including DB1. The program can be saved in a program file or on a
memory submodule using a programmer (on-line mode). Please refer to your programmer's Manual
for a detailed description. In the following, the procedure for saving the program on a memory
submodule inserted in the PLC will be described.
4.4.1 Saving a Program to a Memory Submodule
Only EEPROMs can be used for this saving procedure.
In the case of the S5-90U, a program can be saved on a memory submodule only if the "Compress"
function is activated on the programmer connected to the PLC in on-line mode.
