Hi, I have input card 6ES7321-1BH10-0AA0.It's a high speed card with 0.05ms input delay. But in HW config I unable to set a HW interrupts (missing the interrupts bookmark) . How I set the interrupts for OB40?Thanks. |

Dear Davids100, Have a look here: 6ES7 321-1BH10-0AA0 This input card, does not have Diagnostic functions and no Alarms Interrupts. So that will be the reason you can not select it. Best regards, Wizard |

Hello again, Module6ES7321-1BH10-0AA0is a fast DI module compared with normal DI modules. It means that the DI sends the update of DI process image faster than normal module. When data sheets tells that that module has 0.05ms input delay, it is not the directlly related to the frequency of updating this input within your software as may be your program size is too big and your scan cycle is too big too. For each cycle CPU do the following jobs, Write PIQ, then Execute Program, then Read PII and so on. Scan cycle time =Write PIQ time + Execution Program time + Read PII time. So this time may not too small to catch each change of your DI updates. So if you have too high speed updates and you want to record them without missing any pulse input, HW interrupt is the solution. Hope it helps.
