We have recently purchased four PCIC control net cards. After installing those in our computers two were found to be working properly while the other two generated the following error.

"Unable to Access 1784-PCIC Kernel-mode driver. At least one 1784 - PCIC Card Needs to be Installed"

And the making the RSLinx go irretrievably into stop mode.

We have already,

1. checked the faulty cards in different computers.
2. confirmed that the card status in the device manager dialog box is healthy i.e. there is no yellow mark against the card.

We are using RSlinx lite (we have also checked at pro also) ver 2.41

This problem may be due to this that once we were upgrading PCIC card firmware & power to card was interrupted. after that we start getting this message.

we have also performed "REGSVR32" operation on ab_vbp.drv. this file registered sucessfully.

Status in Device manager (after showing hidden devices) under "non plug & play drivers" tab, then A-B virtual back plane is also on "SYSTEM"

We have also called at ypur USA office they gave us a no of India but finally we are unable to get any response.

We would be really grateful for u regarding this help.

waiting...
