If your application Select for a 1769-L23x controller Select for a 1769-L3 x controller Select for a 1769-L4x, 0000116086 00000 n 0000005316 00000 n 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. We assume you are already familiar with Allen-Bradley CompactLogix or ControlLogix programmable logic controllers (PLCs), RSLogix software, and the EtherNet/IP protocol . Another way to transfer data between processors is with the producer/consumer model. Verify that the data types match as well. Normally, our logic would populate this data file with information that is being sent to the ControlLogix. 0000003316 00000 n A self-running timer is a timer that resets itself at regular intervals. The second tab of the instruction allows us to define the path through which the PLC will send & receive packets. Ok so now we will download our PLC_1 project to its controller and our PLC_2 project to its controller. But again for this video we are only going to focus on two types of messages. 0000116337 00000 n Now, we need to create the data file that will be transferred to the ControlLogix. All CompactLogix CPUs are considered to be in Slot 0 of the backplane. Another resource to check out is DF1 Messaging. The way we will focus on in this months newsletter is using MSG (message) instructions. I believe the PLX31-EIP-MBS4 is a modbus to serial gateway. ControlLogix Messaging (MSG) Instruction - Bryce Automation compactlogix to controllogix messaging - Greenlight Insights No configuration is required for the target processor (where the Outbox tag resides). Next, click on Logic / Map PLC/SLC Messages. The source element is the exact tag that will be read from the Micro820 and the starting array element. The message instruction needs to be triggered with a pulse. Be sure the message is a CIP type message, and that the source element exists. Next, we have the destination element which will be the name of the tags inside PLC 1 which is the PLC we are configuring. The MSG instruction is still used, though when sending or receiving data from older processors. How to set path any idea give me. The same communication path will exist for both my read and write messages. 0000026043 00000 n Open the controller tag database, and in Edit Tags mode, add the following tags. endstream endobj 278 0 obj <> endobj 279 0 obj <> endobj 280 0 obj [281 0 R] endobj 281 0 obj <. Here, well be working with the project of the Initiating processor which will contain the MSG instruction that is getting the data. 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). PDF 1799 Using Intelligent SNAP IO with Allen Bradley Logix Systems - Newark . 0000116222 00000 n When the DN bit is set, the timer resets. Please pay attention to the data types when you add these tags: The Inbox is the tag that we will place data into that we get from the targets Outbox. 0000116759 00000 n 0000006408 00000 n When your PC is on the same network, be sure you can ping both the SLC and the ENBT. his answer ID describes how to create the correct path for a MSG instruction from a ControlLogix processor to another ControlLogix processor using Ethernet with two Ethernet cards (example 1756-ENBT) The controller that initiates the message instruction has the following path (separated by commas, no spaces): 1,S1,2,xxx.yyy.zzz.www,1,S2 Where:
