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. Ok so here we are on the communication tab and the path is empty. 0000004996 00000 n Please enter your comment! Other end prosoft module PLX31-EIP-MBS4 ethernet port 1 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. ControlLogix, CompactLogix, and SLC Message - ProSoft Technology CLX to 1761-net-eni read message : r/PLC - Reddit The MSG instruction is still used, though when sending or receiving data from older processors. Later on, the SLC will think its sending data to another SLC Processor, and storing that data to N70:0 to N70:4. That will reset the rung over and over so the instruction will continually execute. The message instruction needs to be triggered with a pulse. Communication between Controllogix or Compactlogix PLC's with produced Other method to make communication for ControlLogix and CompactLogix PLC's is the Message way, like a generic CIP Message. Specifically Allen-Bradley PLCs, such as ControlLogix and CompactLogix controllers. Remember that in CIP Paths, " 2 " is the Network port and " 1 " is . Ok, so now we have the 3 fields we need to fill in here. Todays video is cool because youre going to learn exactly how to set up communications between two ControlLogix PLCs AND if you have access to Studio 5000 Logix Designer and Logix Emulate you will actually be able set up communications between two Emulate controllers today and test it out. Here is our goal: We will read the targets Outbox tag into our Inbox tag. The producer/consumer model is scheduled. Hi Adam, In other words, the data transfer speed may be impacted by multiple factors thus making it somewhat unreliable. The last path syntax is the correct one. 0000007373 00000 n First, we need to create a control file for the Message instruction to be able to operate. 0000005104 00000 n To do so, right-click on "Data Files" in the project tree and click "New".

As you can see Ive set up PLC_2 in slot 1 of the same chassis as PLC_1. Step 3 Make sure that the tags are in place and are correctly specified on both ends. Another way to transfer data between processors is with the producer/consumer model. Proper configuration of PLC inputs and outputs is crucial for reliable system performance, preventing malfunctions and safety hazards, ensuring data accuracy and optimal operation. However, in the current manufacturing environments, its an absolute must. The initiating processor is the processor on the top of the diagram above. Let's dig into how to set it up. 0000003259 00000 n Maybe you could be a better judge than I, so Ill explain it to you. But if we update an element in PRODUCE_DATA beyond element 9 then it wont update in CONSUME_DATA because we are only reading 10 elements. Try add 1,0 at the end of your path. 0000018122 00000 n Next, click on Logic / Map PLC/SLC Messages. So, when we update the PRODUCE_DATA array in PLC_2 it should be reflected in PLC_1, Notice that updating the PRODUCE_DATA[0] in PLC_2 is updating the value in CONSUME_DATA[0] in PLC_1. 11K views 3 years ago ControlLogix videos from The Automation Minute & Show I walk through programming a ControlLogix with Message Instructions (MSG) to read data from a CompactLogix,. Looking for specifications? This allows two processors to mutually share critical data values similar to the Scanner/Adapter mode used on Remote I/O. All CompactLogix CPUs are considered to be in Slot 0 of the backplane. In fact, when practical, its usually better to do a read for troubleshooting purposes. Leaving the file number at 9, make sure you select Message for the type. So, for this message, we are going to set it up to read tags from a second controller. Serial Communications If it aint broke, why fix it. First, we need to initiate a message in the SLC. Now lets enter this path into our MSG Instruction. ControlLogix 5580 and GuardLogix 5580 Controllers User Manual Download. Message samples for common Rockwell Automation processors through the DH+ bridge on an AN-X-AB-DHRIO or an AN-X2-AB-DHRIO gateway. About it I make later a post, how to do it.

This can be easily checked by looking at the .EN bit of the MSG Instruction. Basically, we just pick an unused files number in the target such as N70. The ladder logic is an excellent start, but were not quite done yet. We will be making two MSG instructions, so we will have to create it with two or more elements. Normally, our logic would populate this data file with information that is being sent to the ControlLogix. The ultimate PLC programming guide for beginners. You solution really helped me out a lot, I hope this small note may help you as well. Now first things first, we will need to assign a tagname to the MSG instruction. One of the simplest ways to pass data between two controllers would be through the use of the MSG instruction. Now first things first, we will need to assign a tagname to the MSG instruction. You just work your way back and forth between A and B to get to your target. Message (MSG) Data to a CompactLogix over Ethernet (M2E25), PLCs vs PACs: Did Digi-Key get it right? This is the most difficult part of messaging. Messaging can be used to send or receive information from an SLC-500 or PLC-5 as well. 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). Port 2 on any Logix network module is the network port. In the ControlLogix, we must map this request to an array of integers. This months blog post topic is all about sending messages between PLCs. 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. 0000089350 00000 n Back on Step B, we will be going into the ENBT on the target chassis, so specify the IP of the target module, 192.168.0.6. 277 92 Launch the Product Configurator to search for drawings by catalog number or keyword. Just like with anything else, its important to know how o troubleshoot. Join SolisPLC and get started with our free courses. In other words, its something you always specify for CompactLogix processors and ControlLogix processors when they go through an ENxT network card. 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). ENBT in slot 4 Ok, that's what a MSG instruction looks like. But again for this video we are only going to focus on two types of messages. 0000004135 00000 n So we will choose CIP Data Table Read. For more information, visit the ControlLogix post page!
