Hello Krrish, To implement you need to have a IM which is cable to save the Event Recording 6ES7 153-2BA02-0XB0 & DI Module Which is 6ES7 326 1BK01 0AB0, Have a Look on the Application Example Here Buffering of Process Messages including Time Stamps with ALARM_7B |

Hello Krrish !! For resolution of 100ms you don't need any fancy hardware. Assuming that the basic cycle time of your plc is generally 10-20ms these days, a SOE program can be created in STEP7 which detects thechanges in stats of of Signals required to be monitored and stores them in a SOE DB along with the time stamp. You could create a DB with say 50-100 events ( even more if needed ). Every time a new event occurs, the oldest event ispushed out. We have done this several times with accuracy of 10-20mswithout any issues. Hope this helps Cheers Navnag |
There is no such thing as the last bug in a program |

New question published by TheCloverTech is split to a separate thread with the subject Time stamping for binary signals with 10 ms resolution. Best regards |
