You may need to be offline to set this, then download. This gets us to the backplane, then to slot 1, and out the front port. 0000007317 00000 n Are you doing an SLC typed write, or a word range write (or read)? This will be 5 Integers. 0000003012 00000 n The Automation Blog, The Automation Show, The Automation Minute, The Automation Podcast, The Automation Guy, The Automation Exchange, The Automation Forums, as well as Automation Tech Tips, Automation Tech Talk, Automation Files, Automation Tutorials, Automation Exchange, Automate News, and Automation Show are trademarks of Insights In Automation all rights reserved. Then, map file #70 to the array we just created From SLC. MSG on ControlLogix (1756-L61) to read/write data to CompactLogix (1769-L32E)1. This instruction would be utilized within the RSLogix 5000 or Studio 5000 programming environments on an Allen Bradley PLC and Write or Read data from a different PLC. Looking for specifications? 0000005104 00000 n So first of all, we need to choose the message type. 192.168.1.4 The ControlLogix requires no other configuration. This model offers a communication rate of 10/100 Mbps and memory capacity options of 2 MB and 3 MB. ControlLogix messaging is used to send or receive information to another processor. This allows two processors to mutually share critical data values similar to the Scanner/Adapter mode used on Remote I/O. At this point, we come out the front port with a 2, then go to the IP 172.25.154.51. For an EtherNet based system, we need to input the address of the MicroLogix PLC and specify that this communication will be sent over CIP. ENBT in slot 4 0000115749 00000 n 0000031413 00000 n 0000116222 00000 n Thanks, Mat You are correct if the target was a ControlLogix processor. Specifically EtherNet/IP. Step 3 Make sure that the tags are in place and are correctly specified on both ends. Your email address will not be published. He spends his days working as a Sr. Controls Engineer in the Pulp & Paper Industry. One of the simplest ways to pass data between two controllers would be through the use of the MSG instruction. 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 :-) Let's dig into how to set it up. 0000005210 00000 n Messages 1756-PM012 Nonvolatile Memory . The 2 which you see at the start of the path definition calls out the fact that were communicating over the backplane first. We assume you are already familiar with Allen-Bradley CompactLogix or ControlLogix programmable logic controllers (PLCs), RSLogix software, and the EtherNet/IP protocol . The ladder logic is an excellent start, but were not quite done yet. Im going to call it CIP_READ_MSG. 0000006019 00000 n Leaving the file number at 9, make sure you select Message for the type. Here, well be working with the project of the Initiating processor which will contain the MSG instruction that is getting the data. To enter the processor from the backplane (Step B), specify 0 for the processor slot #. Another advantage of the message instruction is that no I/O Configuration is required to make it work. If you are working with a running system, the tag can be created while you are online without the need to download. )jW4ZF*:B,]N6XrvSA4H 0000003816 00000 n I hope you found this helpful! 0000023298 00000 n Im not so sure (qa230316), Red Lions New NT5000 Managed Gigabit Switches (P144), TIA Portal V18: Create PLC Program and Test in PLCSim (T010), Industrial PLCs based on Arduino and Raspberry PI (P143), Why Does My CompactLogixs IP Address Keep Changing? Keep in mind that any time you download, your processor will stop executing logic. I worked your solution to my automation laboratory, and have perhaps found a small error in it. Need manuals to help you install, configure, and use your ControlLogix and GuardLogix large control systems? You can breeze through this cheat sheet in about 10 minutes and get a solid understanding of the big picture of how PLCs work. So if we want it to continually run we need to create logic that resets the rung continually. ControlLogix and GuardLogix Controllers Technical Documentation, ControlLogix 5580 and GuardLogix 5580 Controllers, ControlLogix 5570 and GuardLogix 5570 Controllers, ControlLogix & GuardLogix Control Systems Technical Documentation. Your path looks good. For this reason, I adjusted the named arrays in the MSG blocks accordingly. Im also going to place a random value into the outbox tag (in Monitor Tags mode), and download the project to the target processor. If Im understanding correctly, your configuration would not be with the MSG instruction. The ControlLogix Messaging post will help you to build the new path, and has some good examples. Therefore its generally more efficient to build the path manually. Get that working, then solve the ControlLogix message problem. 0000035205 00000 n You'll also find my PLC, HMI, and SCADA courses at TheAutomationSchool.com. In this course, you'll learn the basics of the FANUC Dual Check Safety (DCS) software. It is thus advised to program all the MSG instructions within the same routine. Please enter your comment! 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. We are only going to focus on two message types in this video, but just to give you an idea, there are different types of instructions for talking to different devices or across different networks. Hello Hans. Check out this link if you are interested in learning how to message over DH+ to the older processors. Good day, how do you multihop when the Ethernet modules are sitting on different subnets? ControlLogix 5580 and GuardLogix 5580 Controllers User Manual Download. 0000025200 00000 n Lastly, we can insert values to our ControlLogix tags and verify they are written to the Micro820 controller tags. I believe the PLX31-EIP-MBS4 is a modbus to serial gateway. Each of the green arrows represent a step in building the path to the target processor. 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. . 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. Learn how to use RSLogix 5000 (aka Studio 5000) to message data from one CompactLogix or ControlLogix to another over Ethernet using the Message (MSG) instruction in episode 25 of The Automation Minute Season 2. . Let me know if you have any questions on this. Both of these are heavily utilized in the current manufacturing environments and provide an excellent testing platform. Our message will be sent out of channel 1 of the 5/05 (Ethernet). Can you multihop this, and how? This will be file #9 (Integer), and well name this file MGCTRL. 0000000016 00000 n I have done this on two other processors with no problems. 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. 0000034548 00000 n 0000117007 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. We now need to specify which tags are being read from, which tags are being written to and what the path of the communication between the devices is. 0000004566 00000 n Pingback: Resetting fuses on the ControlLogix 1756-OB16E module. compactlogix to controllogix messaging. If the processor is going out to get the data, the troubleshooter will find the MSG instruction when doing a cross-reference. Later on, the SLC will think its sending data to another SLC Processor, and storing that data to N70:0 to N70:4. Doesnt seem to be working on this particular processor. EN2TRin slot 1 The MSG instructions only run once when the rung is true. The first one is that this method of sending & receiving data isn't deterministic. I'm going to call it CIP_READ_MSG. In other words, the data transfer speed may be impacted by multiple factors thus making it somewhat unreliable. The ControlLogix does not have the same addressing structure as the SLC 500. 0000005863 00000 n 0000007865 00000 n This is actually pretty cool and a fun topic to learn. And then we have the destination element which is where we put the tag name inside this controller that we want to put the data in that we read from the other PLC. In short, there are only a few things to do to get SLC to ControlLogix messaging to work.

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. You wouldnt need to change the path of the message instruction if the new ENBT (or other 1756 Ethernet module) is in the same slot, and your message is going to the same place. If you are interested in learning about ControlLogix to ControlLogix, messaging, visit the ControlLogix Messaging Page. Step 1 Make sure that the ladder is executing the instruction. 0000004781 00000 n Remember that in CIP Paths, " 2 " is the Network port and " 1 " is the Backplane. First, we need to initiate a message in the SLC. A self-running timer is a timer that resets itself at regular intervals. The ultimate HMI development guide for beginners. Message Type: CIP Data Table Read Note: 1,0 at the end of the path (for desti. Also, it is more efficient with using multi-cast communication when communicating with more than one processor. Heres what a MSG instruction looks like in Studio 5000 Logix Designer And heres what it looks like on the inside on the MSG configuration.
