Messaging - How to Get A-B PLCs to Talk to Each Other - myPLCtraining Check out this link if you are interested in learning how to message over DH+ to the older processors. We will make this file 10 (Integer), and it will be 5 elements long. This is my first messaging that I have had to do with these type of controllers over ethernet. 0000118061 00000 n 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. This comes into play when your control system changes and you now need to go back and redirect all the paths. When I programmed your solution exactly, I kept getting 16#0011 and16#0013 errors in my MSG blocks programmed in RSLogix. Here we are in Studio 5000 Logix Designer and we are going to start by adding a rung. From the Initiating L71 processor, look at Step A. Hey guys, its Stephen Gates here from myPLCtraining.com with another PLC training video to help you become a confident PLC programmer. 0000117908 00000 n 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). Here is our goal: We will read the targets Outbox tag into our Inbox tag. Once you are used to how the path works, its very easy to understand. 0000115749 00000 n Join our community of pros to take part in the discussion! The ControlLogix does not have the same addressing structure as the SLC 500. Lastly, we can insert values to our ControlLogix tags and verify they are written to the Micro820 controller tags. Keep in mind that any time you download, your processor will stop executing logic. 0000003083 00000 n Remember that in CIP Paths, " 2 " is the Network port and " 1 " is the Backplane. When your PC is on the same network, be sure you can ping both the SLC and the ENBT. Using this method, the SLC can read or write data to the ControlLogix. Your email address will not be published. Be sure to turn on the MultiHop Feature. How to set path any idea give me. Shawn M TierneyTechnology Enthusiast & Content Creator. Heres a simple example of why youd want to communicate data from one PLC to another. I always recommend reading values from another processor (vs writing). However, in the current manufacturing environments, its an absolute must. 0000116849 00000 n The first one is that this method of sending & receiving data isnt deterministic. Now first things first, we will need to assign a tagname to the MSG instruction. If the path becomes a problem, you may add the secondary PLC into the I/O Tree of the one doing the messaging. If your application Select for a 1769-L23x controller Select for a 1769-L3 x controller Select for a 1769-L4x, ControlLogix 5580 Redundant Controllers User Manual Download. Other method to make communication for ControlLogix and CompactLogix PLC's is the Message way, like a generic CIP Message. Now, we need to create the data file that will be transferred to the ControlLogix. The first one is that this method of sending & receiving data isn't deterministic. The producer/consumer model is scheduled. Explore other topics like networking, machine vision, etc. 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? )jW4ZF*:B,]N6XrvSA4H Remember that when you download, your processor will stop executing its program! 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. Hello Hans. If Im understanding correctly, your configuration would not be with the MSG instruction. When finished, click the Communication tab of the setup screen. This will be 5 Integers. Since the Micro820 used a completely different software for programming, I wanted to test and make sure that data could be shared with other Rockwell controllers. 0000118223 00000 n We must specify 1 to get to the backplane. 0000003316 00000 n 0000007865 00000 n 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. 0000023298 00000 n Below will illustrate this mapping process. 0000117131 00000 n Instead of a single DINT for the inbox and outbox, we could use DINT[10] as the data type, and change our number of elementsto 10 on the Configuration tab of the MSG instruction. When the DHRIO receives a message from a 5/04, it will then pass that data to the 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. When we build the path, we MUST go from Step A to Step B, then repeat the process until we are at the target. Communication between Controllogix or Compactlogix PLC's with produced 0000117759 00000 n 0000116135 00000 n 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. Your help would be very much appreciated. For example, the SLC 5/05 will take 5 integers from the N10 data file, and send those 10 integers to the Allen Bradley ControlLogix processor. Proper configuration of PLC inputs and outputs is crucial for reliable system performance, preventing malfunctions and safety hazards, ensuring data accuracy and optimal operation. I walk through how you can program a ControlLogix with Message Instructions (MSG) to read data from CompactLogix, MicroLogix, and SLC-500 programmable contro. 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. 0000004781 00000 n This allows us to build a structure which will constantly increment the timer and reset once it reaches the peak. 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. LEAVE A REPLY Cancel reply. We will cover the most commonly used options for you to get started with robot safety. To do this, well right click the Data Files folder, and create a new data file. 0000000016 00000 n Can you multihop this, and how? For this example, I will pick an arbitrary file number (70). PLC Programming MSG Instruction - Send Data Between - SolisPLC Proportional Settings for ControlLogix PID Enhanced (PIDE), Integral Settings for ControlLogix PID Enhanced, Derivative Settings for ControlLogix PID Enhanced, Assembly Registers and Compatibility Modes. Your email address will not be published. You can find it here. The MSG instruction provides an easy way to establish communication between two Allen Bradley PLCs. 0000117603 00000 n 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). One for reading data from the Micro820 and one for writing data. I will add this logic to the MainRoutine: This timer will set its DN bit when the accumulator reaches 40ms. Next, we have the destination element which will be the name of the tags inside PLC 1 which is the PLC we are configuring. Now we're going to go through the whole setup for talking between two different Emulate Controllers, but everything except the communication path would be the same for talking between two ControlLogix controllers. Since the ControlLogix has a different addressing structure than the SLC, we must map the SLC message to an array in our tag database. It is one of simplest ways to make communication between ControlLogix PLC with CompactLogix PLC or between two ControlLogix or two CompactLogix.
