We want to send a message from the processor in the first chassis to the processor in the third chassis. We will be making two MSG instructions, so we will have to create it with two or more elements. )jW4ZF*:B,]N6XrvSA4H The ControlLogix does not have the same addressing structure as the SLC 500. The MSG instruction is still used, though when sending or receiving data from older processors. 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,. 0000003083 00000 n So we need to click the Browse button and choose the controller we want to talk to. Your email address will not be published. This comes into play when your control system changes and you now need to go back and redirect all the paths. Message (MSG) Data to a CompactLogix over Ethernet You may need to be offline to set this, then download. PDF CompactLogix Communication Modules Specifications Get that working, then solve the ControlLogix message problem. As long as the routine the MSG instruction is in, and its being executed at regular intervals, he should be getting that error code, which would tell us more information for sure! Message (MSG) Data to a CompactLogix over Ethernet (M2E25), PLCs vs PACs: Did Digi-Key get it right? Open the controller tag database, and in Edit Tags mode, add the following tags. Can you connect to the CompactLogix with RSLinx over ethernet through the NET-ENI module? If you are interested in learning about ControlLogix to ControlLogix, messaging, visit the ControlLogix Messaging Page. 0000004673 00000 n PDF Logix 5000 Controllers Messages (Publication 1756-PM012J-EN-P) 0000004028 00000 n Leaving the file number at 9, make sure you select Message for the type. I walk through programming a ControlLogix with Message Instructions (MSG) to read data from a CompactLogix, SLC-500, and MicroLogix over Ethernet in Episode 29 of The Automation ShowYou can unlock insider news, free downloads, and early access to The Automation Show's episodes when you support our channel at http://patreon.com/automation!- Viewers, please feel free to post questions and comments on this show's post at https://TheAutomationBlog.com or https://Forums.TheAutomationBlog.com- Instructors, you can contact me directly about publishing your courses at The Automation School at: https://theautomationschool.com/instructors-wanted/- Vendors, you can contact me directly about having products featured on the Show, Podcast and Blog at: https://theautomationblog.com/guestUntil next time my friends, PEACE :-) For this example, we need a tag in the target processor named Outbox. PLC Programming MSG Instruction - Send Data Between - SolisPLC 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. 0000007317 00000 n Shawn is a lifelong Technology Enthusiast who as a pre-teen in the early 80's discovered his passion for programing on the newly released Apple II and VIC-20 computers. Shawn M TierneyTechnology Enthusiast & Content Creator. Another resource to check out is DF1 Messaging. ENBT in slot 4 . Ok so here we are on the communication tab and the path is empty. 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. Looks complicated right? The source element is Outbox. 0000034548 00000 n 0000117908 00000 n Step 1 Make sure that the ladder is executing the instruction. LEAVE A REPLY Cancel reply. Since the ControlLogix has a different addressing structure than the SLC, we must map the SLC message to an array in our tag database. Before we start, lets create some tags that we will need for this example. The path would be 1,1,2,172.25.172.68,1,6,2,172.25.154.51,1,0. Lastly, Ive done a speed test on the message response time. I hope you found this helpful! Perfect place to start. To start, we have 1,1,2. On the other hand, if your processor is in a different slot, just configure the DHRIO module using RSWho in RSLinx. 0000035205 00000 n Ok, that's what a MSG instruction looks like. In the tutorial above, we've demonstrated all the steps required for creating this connection between a MicroLogix 1100 and a CompactLogix L24ER PLCs. Look at steps A and B on the documentation. Its absolutely the best PLC training offer on the internet right now. It describes SNAP I/O, discusses explicit and implicit messaging, and provides some architectural details of implicit messaging, the more common method of communication. If the target processor is already in your I/O configuration tree, you could just browse for the processor. RSLOGIX5000 MSG CompactLogix to ControlLogix Ethernet Comm SY P HOANG 2.75K subscribers 2.5K views 3 years ago Rockwell 5000 MSG on CompactLogix (1769-L32E) to read/write data to. To be honest, Ive only used 3 or 4 of the of the different message types, so dont worry, you dont need to learn all of them. Then, map file #70 to the array we just created From SLC. You can configure the DHRIO module so it knows the slot number your processor is in. Click the Setup button within the message instruction. This means that it updates at regular intervals. So how would you setup your path if you had a RSLOGIX5000 MSG ControlLogix to CompactLogix - YouTube Sending Data from a MicroLogix or SLC PLC to a CompactLogix - SolisPLC 0000002136 00000 n First, we need to create a control file for the Message instruction to be able to operate. This model offers a communication rate of 10/100 Mbps and memory capacity options of 2 MB and 3 MB. 0000116489 00000 n You will notice the Enable (EN) bit, the Done (DN) bit, and the Error (ER) bits to the right. Hey guys, its Stephen Gates here from myPLCtraining.com with another PLC training video to help you become a confident PLC programmer. The destination tag is Inbox This is where we place the data we receive from the targets Outbox tag. Join my community of automation professionals and take part in the discussion! This tag will store the status of thedata transfer. Your path looks good. Looking for specifications? You have entered an incorrect email address! 17. after it download both programms to the PLCs. The MessageTimer will be used in logic to give the message instruction a pulse at regular intervals. We will make this file 10 (Integer), and it will be 5 elements long. These tags are of the same DINT[] data type. Thanks, Mat You are correct if the target was a ControlLogix processor. 0000006485 00000 n So for example, we have PLC5 type messages and SLC type messages and even PLC2 messages which are are super old PLCs that came before the PLC5. The ControlLogix requires no other configuration. PLC Programming MSG Instruction - Send Data Between MicroLogix & CompactLogix PLCs Studio 5000 Tutorial. You have entered an incorrect email address! Find more documentation for Allen-Bradley hardware and FactoryTalk software products. Specifically EtherNet/IP. I set up my logic as follows: Next click on Setup Screen within the MSG instruction. Explore other topics like networking, machine vision, etc. You have to be careful because the word length might not mach up if you are sending a DINT to the SLC (which is 16 bit). 0000117131 00000 n Now lets go to the communication tab to make sure that this message reaches PLC 2.
