1,4,2,192.168.10.204,1,0 Using this method, the SLC can read or write data to the ControlLogix. With Ethernet, usually if you have multiple devices on a network, they all connect to a "hub" called an Ethernet switch. Now lets go to the communication tab to make sure that this message reaches PLC 2. There are a few things you should keep in mind when using MSG instructions.

Learn the fundamentals & best practices of industrial robotics. This publication links to a collection of programming manuals that describe how you can use procedures that are common to all Logix5000 controller projects. 17. The CompactLogix and ControlLogix processors support Producer/Consumer Tag mapping between two processors. Over the years, Ive seen many reasons for which an MSG Instruction will fail. The way we will focus on in this months newsletter is using MSG (message) instructions. Verify that the data types match as well. 277 0 obj

There are a couple different ways that we can configure Allen-Bradley PLCs can talk to each other. Resetting fuses on the ControlLogix 1756-OB16E module. The ControlLogix does not have the same addressing structure as the SLC 500. If you are new to PLCs or just looking to get a better handle on how they work, check out this free cheat sheet, called the "Motivated Electrician's Guide to Understanding ANY PLC System.". The message will be a Peer to Peer write, and the control block is N9:0. 0000117007 00000 n
The destination tag is Inbox This is where we place the data we receive from the targets Outbox tag. It describes SNAP I/O, discusses explicit and implicit messaging, and provides some architectural details of implicit messaging, the more common method of communication. Messaging - How to Get A-B PLCs to Talk to Each Other - myPLCtraining What I found is that is does allow for CIP reads and writes and that makes it a team player. To create an array, use the [1..20] syntax in the dimension column to create the needed amount of array tags. ControlLogix Reading Data From CompactLogix, MicroLogix, and - YouTube The MessageTimer will be used in logic to give the message instruction a pulse at regular intervals. Next, let's go to the Input/Output instruction tab and grab the MSG instruction. In the tutorial above, weve demonstrated all the steps required for creating this connection between a MicroLogix 1100 and a CompactLogix L24ER PLCs. I believe the PLX31-EIP-MBS4 is a modbus to serial gateway. At this point, we come out the front port with a 2, then go to the IP 172.25.154.51. 0000014877 00000 n
This gets us to the backplane, then to slot 1, and out the front port. September 2015 For the write MSG instruction, we will use the CIP Data Table Write type. 0000116086 00000 n
For more information, visit the ControlLogix post page! And if this tag array hasnt been created yet you can just click this handy New Tag button. 0000116135 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. When finished, click the Communication tab of the setup screen. I walk through how you can program a ControlLogix with Message Instructions (MSG) to read data from CompactLogix, MicroLogix, and SLC-500 programmable contro. Lastly, we can insert values to our ControlLogix tags and verify they are written to the Micro820 controller tags. You need to make sure that the instruction is set to read/write correctly and that the path is defined exactly as its established in the real world. Sending Data from a MicroLogix or SLC PLC to a CompactLogix - SolisPLC We have a third chassis with a processor in slot 0, and an EN2T in slot 1 with an IP address of 172.25.154.51. But again for this video we are only going to focus on two types of messages. 368 0 obj

So how would you setup your path if you had a Furthermore, the same instruction would work between any RSLogix/Studio 5000 and RSLogix 500 based Programmable Logic Controllers. Ok, so back to the topic at hand. Lets say, we have a processor in slot 0, and an EN2T in slot 1 of the local chassis with an IP of 172.25.172.67. 0000005210 00000 n

When your PC is on the same network, be sure you can ping both the SLC and the ENBT. For this example, Ill just type in 5 random numbers.

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. . The #1 platform for automation training and workforce development. 0000007451 00000 n
Maybe you could be a better judge than I, so Ill explain it to you. ControlLogix Reading Data From CompactLogix, SLC-500 - YouTube Also, it is more efficient with using multi-cast communication when communicating with more than one processor. First, we will create an array called FromSLC in our Controller Tag Database. The ladder logic is an excellent start, but were not quite done yet. Now first things first, we will need to assign a tagname to the MSG instruction. In the tutorial above, we've demonstrated all the steps required for creating this connection between a MicroLogix 1100 and a CompactLogix L24ER PLCs. LEAVE A REPLY Cancel reply.

Here, well be working with the project of the Initiating processor which will contain the MSG instruction that is getting the data. This comes into play when your control system changes and you now need to go back and redirect all the paths. Im going to call it CIP_READ_MSG. All CompactLogix CPUs are considered to be in Slot 0 of the backplane. 0000006019 00000 n

As you can see Ive set up PLC_2 in slot 1 of the same chassis as PLC_1. A self-running timer is a timer that resets itself at regular intervals. trailer
In fact, when practical, its usually better to do a read for troubleshooting purposes. 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.

L73 processor in slot 0 I always recommend reading values from another processor (vs writing). It is thus advised to program all the MSG instructions within the same routine.

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. Need manuals to help you install, configure, and use your CompactLogix and Compact GuardLogix small control systems? The path would be 1,1,2,172.25.172.68,1,6,2,172.25.154.51,1,0. Proper configuration of PLC inputs and outputs is crucial for reliable system performance, preventing malfunctions and safety hazards, ensuring data accuracy and optimal operation. If you want more details on setting up messages between ControlLogix or CompactLogix controllers then check out the free bonus lesson coming up. 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.

You can find it here. The message instruction needs to be triggered with a pulse. Next, Ill download to the processor, then well verify the Inbox tag of the Initiating processor matches the Outbox tag of the target processor. The Micro820 can control a smaller scale system as well as report back to the rest of the control system any needed data that needs to be shared. This will bring up the configuration screen. You just work your way back and forth between A and B to get to your target. You solution really helped me out a lot, I hope this small note may help you as well.
