Dear User, S7-PLCSIM can not imitate the whole functionality of a real Hardware: What is the difference between S7-PLCSIM and a "real" automation system?and SFC81 is one of the cases.Please test your program with an actual hardware.

Hello Manish@TCS, SFC 81 is a standard function for S7 300/400. See here for details: Manual: System Software for S7-300/400 System and Standard Functions Volume 1 and Volume 2 regards |

Hello MANISH@TCS , Just to add a small point, the instruction manual for a family of CPUs also provides the list of all supported basic instructions and system functions.For each case, you will find an approximate execution time.For your case, check your CPU , if it is listed in applicable modules.Then have look in page 137: https://support.industry.siemens.com/dl/files/435/23904435/att_89274/v1/OP-Liste_en.pdf another point, if you are not able to test the function, others here can test and upload a snapshot for you. I hope this helps, hdhosseini |
