In order to accomplish this, were going to leverage a simple repetitive timer through a TON Instruction, paired with an XIO Instruction based on the completion. 17. Lets say PLC 1 controls one steam boiler and PLC 2 is the main plant PLC that monitors the alarms all the boilers in the plant and other equipment as well. The attached document contains both read and write message samples from a ControlLogix, CompactLogix, and SLC 5/05 processors to an SLC 5/04s and PLC5 processor on a DH+ network through the DH+ bridge gateway. I have tried 1,4,2,192.168.10.204. The ControlLogix Messaging post will help you to build the new path, and has some good examples. Since the Micro820 used a completely different software for programming, I wanted to test and make sure that data could be shared with other Rockwell controllers. Thank you so so much for posting this excellent solution to a complex problem. Second, the number of elements to read and last, the ControlLogix tag to place the data once it is read and the array element to start with. At this year's Rockwell Automation TechED, one new library management tool for Studio 5000 Logix designer was debuted. Thepath will be 1, 3, 2, 192.168.0.6, 1, 0 Go through those steps a few more times until you are comfortable and understand how we got this path. Step 1: after you already added your plc with the program and logic, just add new network adapter to your PLC (in this case I use 1756-ENBT), Step 2: put name, slot and IP adress in config window, Step 3: now you have to add a parner network card (do same like in step 2). So first of all, we need to choose the message type. ControlLogix, CompactLogix, and SLC Message - ProSoft Technology Next, we specify the target IP, which is 172.25.172.68, then we go to the backplane with 1, and then 6 to slot 6. So this we will call this CONSUME_DATA and starting at element 0, so CONSUME_DATA[0]. For this example, we need a tag in the target processor named Outbox. About it I make later a post, how to do it.

Ricky. Below will illustrate this mapping process. When a person is troubleshooting a problem from Outputs back to the source, they can cross reference a data file that will trace back to the message read instruction to see where the data is coming from. The source element is the ControlLogix tag that will be written to the Mirco820 controller and the number of elements is how many elements to write. That will reset the rung over and over so the instruction will continually execute. Find release notes, AOP, EDS, firmware, and other product files inthe Product Compatibility and Download Center (PCDC). In fact, when practical, its usually better to do a read for troubleshooting purposes. Ok, so now we have the 3 fields we need to fill in here. We will cover the most commonly used options for you to get started with robot safety. Looks complicated right? When finished, click the Communication tab of the setup screen. To create an array, use the [1..20] syntax in the dimension column to create the needed amount of array tags. For more information, visit the ControlLogix post page! The CompactLogix and ControlLogix processors support Producer/Consumer Tag mapping between two processors. In contrast, the CCW arrays were configured starting at 1, and ending at 20. Remember that in CIP Paths, " 2 " is the Network port and " 1 " is . In the tutorial above, weve demonstrated all the steps required for creating this connection between a MicroLogix 1100 and a CompactLogix L24ER PLCs. 0000021524 00000 n 0000016408 00000 n Messaging Controllogix-Compactlogix HELP! - PLCS.net - Interactive Q & A When I go back to the ControlLogix processor, I can see that Im receiving the data that I placed into the N10 file in the SLC.
