Hello there,

I have problem with Bypass Link in ILck8x4L. I've got several inputs in Interlock which should be bypassed. I have interconnected BypLixx (where xx - number of input, 03 - for example) with external condition. So I have bad signal in interlock input In03, but I also have BypLi03 = 1. But interlock's out is still 0. But if I set up ByIn03 = 1, interlock's out will be 1. Seems like BypLi is ignored. I've tried to set up BypEn.In03 = 1. But it's still the same.

Furthermore, I've found that ErrorNum is -1, so I've found information in manual that's block is not executed. And all status words are all 16#0000000. But Status5 corresponds to active bypasses in every input, and it was still total zero even when I changed ByIn. 

So i would be glad if you help me to find the way to solve this problem.

Additional info: PCS7 v9.0, APL v 9.0.

Thanks in advance.

Hi Krakish,

I have the same problem with the input BypLixx. With input BypInxx of the bypass it is working.
The only advice I can give you is to use the newest version of the APL. You can download the newest Version under the download page SIMATIC PCS 7 V9.0 Software Updates.

With regards
