Also, when I right click on the NI supplied driver and try to force it to install, I get an error that the digital signature of the driver can't be verified.Īm I creating problems by trying to use the driver that came with the Allen-Bradley software? At the moment, this is the only driver I can get to install.
I see in the Kepware documentation that the DH+ driver isn't compatible with 64 bit machines, so this might be an issue (I'm running Windows 10 on a 64 bit machine). When I try to install the DH+ drivers that came with NI OPC Server 2016 (the ones that look similar to the Kepware drivers in the link you sent), Windows won't install them. One thing I have realized though is the drivers for the 1784-PKTX card are drivers I downloaded from Allen-Bradley. I tried this on another PC that never had RSLinx installed, and still no luck. Is there a specific driver I need to be using for the card aside that is different from the Allen Bradley supplied driver? Any help would be appreciated. I have tried several different channel settings, station address numbers, etc. I get the following error:įailed to locate PKTXChannel1 of card PKTX0 The problem is when I go through the card configuration with NI OPC server, with the same settings as I use in RSLinx, it doesn't want to see the 1784-PKTX card. I got to this point by installing Allen Bradley's drivers for the 1784-PKTX card. I have successfully used Allen Bradley's RSLinx software to confirm that the PC can see the PLC on the network. I have NI OPC server 2016 installed, and it seems like it supports communication with the 1784-PKTX card. Our PC (Windows 7) has a 1784-PKTX card to interface with the DH+ network.
I am trying to grab some data from an Allen Bradley SLC500 PLC over a Data Highway (DH+) network and pull it into LabView 2017 for datalogging.
