In my experience, messaging data between ControlLogix or CompactLogix controllers is no more difficult than with any other A-B PLC, and in the below video I walk through how to Read Data into a ControlLogix from a CompactLogix, SLC-500, and MicroLogix over Ethernet: Video - Logix read from Logix on Ethernet: https://theautomationblog.com . I walk through how you can program a ControlLogix with Message Instructions (MSG) to read data from CompactLogix, MicroLogix, and SLC-500 programmable contro. Hello Hans. The source element is the exact tag that will be read from the Micro820 and the starting array element. 0000116086 00000 n 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. Message to a CompactLogix over Ethernet, S2 E25 [] Reply. You might look at the control tag for the message block to see what error you are getting. The Micro820 will only have the array tags that will need to be created for reading from and writing data to. 0000006485 00000 n For the purpose of this tutorial, we specify that the instruction will be used as an SLC Typed Read, will read from the tag B12:0 and store the data into a controller based tag MSG_ML1100_B12_READ. 0000030610 00000 n real-time I/O messaging and message exchange. I have a Logix5562 controller that communicates through an ENBT module onto a network. 0000007317 00000 n SoftLogix, 5069 CompactLogix, Studio 5000 Logix Emulate . So that looks like this. Specifically EtherNet/IP. If you are working with a running system, the tag can be created while you are online without the need to download. The 2 which you see at the start of the path definition calls out the fact that were communicating over the backplane first. 0000117603 00000 n https://www.youtube.com/watch?v=7_pOhn45OdA Hopefully, that will get you pointed in the right direction. Maybe you could be a better judge than I, so Ill explain it to you.

Join SolisPLC and get started with our free courses. From the Initiating L71 processor, look at Step A. Learn the fundamentals, and best practices of HMI development. Now that we are on the ENBT module, back on Step A, specify 1 to get to the backplane. Logix Application Code Manager, as seen at TechED 2015 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. In this course, you'll learn the basics of the FANUC Dual Check Safety (DCS) software. If Im understanding correctly, your configuration would not be with the MSG instruction. hb```b`td`c`0fb@ !Vv"X9z.2LRaac@cb&p ux:-p 53d5* Think of PLC 2 as the Plant SCADA PLC that allows an operator in the main control room to get an overall look at the plant from his control room. So this we will call this CONSUME_DATA and starting at element 0, so CONSUME_DATA[0]. Launch the Product Configurator to search for drawings by catalog number or keyword. First, we need to initiate a message in the SLC. Now, we need to create the data file that will be transferred to the ControlLogix. Ok, that's what a MSG instruction looks like. Resetting fuses on the ControlLogix 1756-OB16E module. 0000117131 00000 n %%EOF The ultimate PLC programming guide for beginners. Sometimes, a message write is more practical, though, to limit bandwidth, and write a message only when a change in data occurs. So, for this message, we are going to set it up to read tags from a second controller. You'll also find all of our automation courses at TheAutomationSchool.com. At the bottom of the help file there is a link to the error codes. Ok, now the configuration window pops up and so from here we will need to set up the rest of the message configuration. View the CompactLogix 5570 Controllers product page ControlLogix Chassis and Power Supplies. Even though the Ethernet port is physically located on the CPU module for the CompactLogix controllers, they still use a CIP Backplane object so they are consistent with the modular ControlLogix controllers. Normally, our logic would populate this data file with information that is being sent to the ControlLogix. There are a few things you should keep in mind when using MSG instructions. Now lets go to the communication tab to make sure that this message reaches PLC 2. ControlLogix & GuardLogix Controllers Technical Documentation Ok so here we are on the communication tab and the path is empty. Looks complicated right? Your help would be very much appreciated. . The CIP Data Table Read and CIP Data Table Write. after it download both programms to the PLCs. 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. PLCs are really not that complicated. Theres no solid requirement here, but its definitely recommended not to send data too frequently if it isnt critical. The source element is Outbox. Good day, how do you multihop when the Ethernet modules are sitting on different subnets? For controller specifications, see CompactLogix Controllers Specifications, publication 1769-TD005. Need manuals to help you install, configure, and use your ControlLogix and GuardLogix large control systems? On the other hand, if your processor is in a different slot, just configure the DHRIO module using RSWho in RSLinx. Communication between Controllogix or Compactlogix PLC's with produced The target processor is the lower processor in the diagram above. First, we will look at the MSG CIP Data Table Read setup. You'll also find my PLC, HMI, and SCADA courses at TheAutomationSchool.com. 0000004781 00000 n Messaging from Control Logix to a Micrologix 1100 0000117291 00000 n Step 3 Make sure that the tags are in place and are correctly specified on both ends. Shawn M TierneyTechnology Enthusiast & Content Creator. Other trademarks are property of their respective companies. Lastly, Ive done a speed test on the message response time. Basically, we just pick an unused files number in the target such as N70. ENBT in slot 4 First, we will create an array called FromSLC in our Controller Tag Database. Have a question? Im trying to communicate with a Micro820 controller on the same network. He spends his days working as a Sr. Controls Engineer in the Pulp & Paper Industry. Ok, so we are going to read 10 elements of the PRODUCE_DATA array from PLC 2 and place it into the first 10 elements of the CONSUME_DATA array in PLC 1. my read command from the ControlLogix keeps showing coms errors. When another processor is writing, its more difficult to trace where data is coming from in the processor that is being written to (without documenting this in the project). For my setup, I browse to the EtherNet module in slot 2, then add a 2 for EtherNet communication and then the IP address of the Micro820 controller. Next, click on Logic / Map PLC/SLC Messages. The SLC would just send data to the DHRIO module. On another note, Adam Im sure you know this Be sure the ENBT has an IP address that is in the same subnet as your SLC. With Ethernet, usually if you have multiple devices on a network, they all connect to a "hub" called an Ethernet switch. We will just name this file TOCLX. Find release notes, AOP, EDS, firmware, and other product files inthe Product Compatibility and Download Center (PCDC). Perfect place to start. Remember that when you download, your processor will stop executing its program! To verify that communication is working, we can add values in the Micro820 controller tags and see if the ControlLogix tags are populated with the data. In ControlLogix, he would be accessing the ENBT by its IP address, but then would need to enter 1 to get to the backplane, and 0 if the processor was in slot 0. Then the number of elements we are reading, so if its a tag array inside the source controller we can choose how many elements of the array we want to read. 0000004351 00000 n Contact us: TheAutomationBlog.com/contact. The ControlLogix does not have the same addressing structure as the SLC 500. Your email address will not be published. Your path looks good. No configuration is required for the target processor (where the Outbox tag resides). Connect your laptop to the same network & use the ping x.x.x.x command to check connectivity to both PLCs.
