SIEMENS 6ES5927-3SA12 FAQ


Q1: What does the 6ES5927-3SA12 board actually do?
A: It is the central processor card (the CPU 927) for vintage Simatic S5-150U and S5-150S setups. The 6ES5927-3SA12 SIEMENS runs your main user logic, handles basic math and timers, and drives all the signals going out to your I/O racks.
Q2: Is the 6ES5927-3SA12 still in production?
A: No, this module was discontinued a long time ago. If your system breaks down and you need a quick replacement, you can buy a fully tested, functional 6ES5927-3SA12 SIEMENS unit straight from our Spare Center.
Q3: Where do I plug in my PG cable on the 6ES5927-3SA12?
A: You cannot plug it into the front panel. The 6ES5927-3SA12 hardware was built without a dedicated programming port on the front face. To get online with the 6ES5927-3SA12 SIEMENS, you have to route your connection via the backplane pins or use a separate CP communication module.
Q4: Will a main power failure wipe the 6ES5927-3SA12 memory?
A: Yes, if your chassis battery is dead. The 6ES5927-3SA12 SIEMENS keeps its data inside volatile RAM blocks. It depends entirely on the backplane battery to keep that data alive during a blackout. If that battery fails while the power is off, the 6ES5927-3SA12 SIEMENS completely loses your program.
Q5: Can I run a 6ES5927-3SA12 with other coprocessors?
A: Yes, the module supports multi-processor configurations. You cannot put two main CPUs in the rack, but the 6ES5927-3SA12 SIEMENS plays nice with specialized communication processors (CP) or positioning modules (IP) sharing the same backplane.
Q6: How do I permanently replace a system built around a 6ES5927-3SA12?
A: You will have to do a full migration to the current S7-1500 line. Keep in mind it is a major rebuild. Moving away from the 6ES5927-3SA12 SIEMENS means your engineering team has to manually rewrite all the old Step 5 code into TIA Portal and replace all the old S5 hardware.
