PV1000 and ControlLogix

I have a PanelView1000 (2711-T10C20) rev 4.20 that is currently polling data from a SLC5/05 but now I need to poll data from a ControlLogix1555 CPU (v15.3) with a 1756-ENET/B. Does anyone know if this combination of revision and modules will work?

This is ringing a bell for me. I think a couple years ago we tried this exact combination, and had to replace the 1756-ENET, with a 1756-ENBT card

That revision of PanelView is perfectly capable of exchanging data with a ControlLogix over Ethernet. You can even set it up as an I/O device for pushbutton control.

The principal trick is to set the Path as well as the IP address in the PanelBuilder32 communication configuration. "1" is the backplane, then a space, then the slot number of the ControlLogix.

For a PanelView connected to a 1756-ENBT at address 192.168.1.55 and a controller in Slot 0, the Address would be "192.168.1.55" and the path would be " 1 0 "

Ken, thanks for the info. So is Curly's statement true that I will have to upgrade to a ENBT module?

My eyes must be playing tricks on me (this is Hour 17 of my workday), I thought you said at first that you had a 1756-ENBT. With product codes that sound so alike on the phone, I've started to get pretty good at radio-speak: "that's echo november bravo tango."

My answer is still accurate, though; the -ENET/B and -ENBT/A have the same functionality but not the same performance.

For ordinary polling of tags, the PanelView can communicate through a 1756-ENET/A, or 1756-ENET/B, or 1756-ENBT/A. All of these perform the same tag data access functions.

For an I/O connection, you need the 1756-ENET/B or 1756-ENBT/A. The -ENET/B is old, but not dead. It will only do about 900 Class 1 frames/second instead of 4000 frames/second like the -ENBT/A (and wait till you see the -EN2T)

Sounds good. Gigabit support I hope?

Rockwell Automation Increases EtherNet/IP Performance and Capacity for ControlLogix Systems

New modules include USB ports, easy setup and replacement


MAYFIELD HEIGHTS, Ohio, Nov. 2, 2006 - ControlLogix users with high-performance or capacity networking requirements now have two new EtherNet/IP module options recently added to the Allen-Bradley ControlLogix family of controllers from Rockwell Automation. The new modules are the first products from Rockwell Automation to feature the Intel IXP465 network processor chip designed specifically for the rigorous performance demands of manufacturing environments.

"Manufacturers are dramatically increasing the use of the information and control capabilities built into the ControlLogix platform," said Joe Lee, product manager at Rockwell Automation. "By enhancing our communication products for ControlLogix, our customers can take advantage of the speed at which plant-floor information is captured and distributed throughout the enterprise."

Ideal for users running demanding I/O and bridging applications, or applications with a large volume of human-machine interface (HMI) traffic, the new modules work with existing EtherNet/IP products and provide capacity to allow for future expansion of users' networks. With connectivity now available for twisted pair (EN2T) and fiber (EN2F) cables, the new modules provide an answer for applications with high I/O, drive, peer-to-peer, and bridging traffic than was previously available with the existing Rockwell Automation 1756-ENBT product line. The new one-slot EtherNet/IP modules support twice the I/O capacity of the existing module, while accommodating four times the HMI activity. This means the modules can transport 10,000 packets per second.

The new modules also include some user-friendly features. A USB port, located on the front of the module, provides easy access to the ControlLogix system. An engineer can use a laptop computer, connected via a standard USB cable, to make updates, troubleshoot and configure their entire system, without the need for custom PC configuration. Further, three rotary switches on the top of the module enable users to set their IP address as an alternative to other software methods. The copper version of the EtherNet/IP module will be available globally in November 2006, while the fiber module will follow in early 2007.
