Hello plcgd; The S5-115U, CPU 944, can hold the complete program in its internal RAM memory, as you can see from the extract from the S5-115U manual, below: https://support.industry.siemens.com/cs/ca/en/view/1085937 Using an EPROM submodule allows you to keep the program even in case the battery suport fails. Using a RAM submodule or the internal RAM memory allows faster daownloads and uploads, but if you lose power and the battery support at the same time the program will be erased. Hope this helps, Daniel Chartier |
