you can use fast nck input. check 840D DoconWeb, LIST for NC Varables and check "Function Manual Extended Functions" (A4) for digital nck i/o. i checked your atc programm. i think you will know how to modify NC prog.to jump to msg"abc" then jump to end( using GOTO) br. |

Hi I assume that your system is a 840. You can use "Read/write PLC variable" function. For that you must write the variable in the PLC with the FC 21 function and read it in the part program with &A_DBB for example. For more information please read (i.e) following documentation: https://www.automation.siemens.com/doconweb/pdf/SINUMERIK_SIMODRIVE_04_2010_E/FB1.pdf?p=40#page=40&view=FitBH,0&pagemode=none Another way is to use a M function which in PLC toghether with your memory bit to generate an allarm. In the part program you can use a GOTOF... to jump at the end of the program. Good luck Nit |
