Special requirements when using the power supply PS 60W 24/48/60VDC HF
S7-1500 - Extended retentive memory for CPUs as of FW V2.1.0
When you use the PS 60W 24/48/60VDC HF system power supply, the entire data area can
be used as retentive memory for CPUs as of firmware version V2.1.0 and higher.
The PS 60W 24/48/60VDC HF supplies enough energy in case of a POWER OFF that the
CPU can save the entire data area retentively.
Requirements
●
STEP 7 V14 SP1 or higher
●
PS 60W 24/48/60VDC HF system power supply
●
CPU with firmware version as of V2.1.0, see table below
Applicable CPUs
The size of the retentive memory depends on the size of the work memory for data of the
CPU used. The table below shows the applicable CPUs with the required hardware function
versions.
