ControlLogix and RSLinx 2.56

Hi,
I am trying to get RSlinx Version 2.56 to see a 1756-DHRIO/E card in a controlLogic Chassis.

The Chassis is 17 slot with a L71 in Slot 0 and the DH+ card in Slot 1.

RSLinx sees the card and shows it as a Yellow ? mark with no X. it labels it as 1756-DHRIO/E and as Unrecognized Device. I have downloaded the latest EDS which is 7.001, but the module I have is a 7.003

Reading the manual it says to configure the card in RSLinx by Right Clicking and go to Module Configuration. However my RSLinx does not show that option.

Is it a case of having to upgrade RSLinx? This project is using the Rockwell PLC5 to ControlLogix chassis conversion with 2 X 17 slot racks connected via EN2T cards. I am trying to setup a opc link from the L71 to the original RSView 32 V7.5 Application.

Any help appreciated.

Andrew

Welcome to the Forum!

Your RSLinx revision is more than ten years old; is there a reason to use it?

RSLinx Lite latest release is 3.90 and the install package is a free download at:

http://compatibility.rockwellautoma...umb=112&refSoft=1&toggleState=&versions=51543

I'd go at least to 3.80 if not the latest.

Thanks for the quick reply.

The only reason is that we use a standard image for our equipment - which is about 10 years old!

Will RSLinx Lite give me the OPC connection I need or does that only come with the full version?

Thanks gain
Andrew

For RSLinx OPC connectivity you will need at least the "Single Node" RSLinx Classic package; "Single Node" supports only one controller; for multiple controllers you will need the "OEM" or "Gateway" package.

RSLinx Lite latest releases do not provide any OPC connectivity, however, they will allow you to upload or create an EDS file from any RA/AB connected devices.

Thanks Again

This is a bit of a shot-in-the-dark...consider doing this process:

1. Exit and shutdown RS-Linx
2. Run the EDS Hardware Installation tool within RS-Linx Tools to install the 7.001 EDS file.
3. Re-start RS-Linx and look for the DHRIO/E

The 7.001 EDS should be fine for all v7 modules (my system only shows 7.001 and I can see a 7.002 module). I'm quite sure I could see this module under 2.56, but have since upgraded.

OK Mispeld,

As suggested followed your instructions and unfortunately no difference, but definitely worth a try.

Thanks
Andrew

The last thing I can think of (short of RS-Linx upgrade) is to verify communication with the module. One way is to right-click on the DHRIO in RS-Linx and display Device Properties. It should respond with a few details, possibly including an EDS file name. This is what it shows for the 7.002 mentioned earlier: 0001000C001207XX.EDS

EDS files help RSLinx Classic identify devices on a network and in a chassis. They tell the software what kind of device it is and what kind of features it has.

RSLinx includes a little configuration applet for the 1756-DHRIO. It has been there since the very beginning in 1998, back before there were even ControlLogix L1 CPUs.

But because RSLinx doesn't know the module is a 1756-DHRIO, it doesn't know that it should make the DHRIO configuration applet available when you right-click.

You should be able to manually download the DHRIO's EDS file from the Rockwell EDS server, using the category "network independent" and the 1756-DHRIO part number. It's also attached to RA Knowledgebase article ID # 57332 (TechConnect Required).

Another Knowledgebase article (67808) suggests that you might have to do the classic "delete the harmony cache files" method to get RSLinx to offer you the 1756-DHRIO configuration applet.

Thanks for the feedback guys, that all makes sense Ken

I did go ahead and upgrade to 3.74 - the highest I could go using WinXP SP3. apart from the fact it wouldn't fit on the 4GB CF card all that is now sorted out.

Now I am trying to establish the link between the L71 and the RSView application. When I setup the topic, I get the option in Advanced Communication of Local or Remote addressing.

I am stuck here on which to use. If I use Local I get nothing when I go to copy DDE/OPC Link when I drop down the Online box under RSLinxOPC Server.

If I choose Remote I am asked for a path to the 1756-DHRIO module.

Again not sure where to go from here.

Andrew

Unless running RSLinx Gateway and the DDE/OPC Server is located on a different PC than RSLinx you need to use the Local addressing mode.

Also, RSLinx Classic needs to run as a Service in order to be able use the DDE/OPC Server feature.

Ok,

All good now.

Thanks

Since you upgraded to a version that requires FactoryTalk Activation, you may want to verify RS-Linx is being properly activated, especially if you were previously using master disk activation. An un-activated new installation will work for seven days until the grace period runs out. All will seem good until it suddenly comes crashing to a halt.

You are probably fine, but the couple minutes to check in FT Activation Manager is worth the effort.
