ACCU1 and ACCU2 have the same behavior in STEP7, whether for 2 or 4 accumulators. ACCU1: Main Accumulator ACCU2: Accumulator secondary |

Hi Pinpon and JMJ I have got an answer for the German hotline to day and the confirm JMJ post . Quote: Thank you for your inquiry to the A & D Technical support.The behavior you describe is a normal for PLCSIM. PLCSIM works like a PLC 400. The PLC 400 has four accumulators. If you make a addition in a PLC 300 you has in the accu 2 the last value from accu 1. In a PLC 400 you have only the resolut in accu 1. The worthy of the other accumulators slip after.(accu3-->accu2)What is the difference between S7-PLCSIM and a "real" automation system?http://support.automation.siemens.com/WW/view/de/11610958S7-PLCSIM supports four accumulators like a S7-400 CPU. In some cases a program running on S7-PLCSIM with four accumulators might behave differently than on an S7-300 CPU that only has two accumulators. I have also been though some old papers and found something that explain the behavior of the accumulators for the CPU’s , See the attachment by the way the load instruction has no effect on accumulator 3 and 4.
