STEP 7 Update for CPU 300

Important notes

Note for STEP7:

• To operate this CPU you need STEP7 V5.4 + SP3 or STEP7 V5.2 + SP1 with HSP 0125 or higher.

• The firmware update V2.6.11 contains the following corrections:

• After power ON, sporadic actual value losses no longer occur after overall reset with event ID 16#6522 or 16#4580 ( backup buffer inconsistent ). No more sporadic defect Z1=97EA when monitoring blocks or variables with simultaneously connected HMI devices.
  If a DB is present, the SFC 24 "TEST_DB" now always returns the correct length of the DB, regardless of its memory attribute or the SFC83 called in parallel. When setting the clock forward, the day of the week ( variable "OB10_DATE_TIME" ) is now immediately set in the local data of the OB10.
