Hello Guys, I am using a nx102-9000 CPU and trying to communicate explicitly to a Telsonic Mag Generator. I have done this on a CJ2M & an Allen Bradley Processor successfully before but am struggling with sysmac. I will attach some screen shots of the AB message instruction because it is much more simple then the CJ2M (required pretty much a full function block made). If anyone wants to see the CJ2M block let me know. I am working right from the sysmac manual using the CIP OPEN, READ, SEND, & CLOSE. Once it is working I will write as well. I am getting stuck right on the first part "CIP OPEN" I am using a route of '02\10.203.21.40' I am unsure what the 02\ means. I am just copying it from the example. The IP Is correct. Below is the picture of my 1C05 Error. Which in the manual is confusing because they have a 1C error and an 05 error separately. Another question (once i can open a connection) is in the CIPRead the 'srcdat' I am not really sure what this is? Everything i've used before is an instance number, class, and attribute number (used in the CIPSend Logic From Allen Bradley MSG Instruction & Current Sysmac logic shown in pictures as well. Please let me know if you have any suggestions or need any additional information. Thanks, Kevin

Hello, Just made this account to get an answer hopefully quickly. I have an existing Omron CJ1M that is talking to a ControlLogix over a CJ1W-EIP21. I don't have experience in configuring Omron PLC's, but the Omron and Allen Bradley are already messaging to each other. My question is how can I get more words to be transferred between the two plc's? There are already 4 words (INTS) being transferred and are working properly but I have used up all the bits and am now needing at least 2 more words. I know in RSLogix 5000 I need to make the array size bigger, but where/how do I do that in CX-Designer? Thank you for any help.

Help required for explicit messaging for CJ2M plc with MURR Block
viraj shah posted a topic in CX-Programmer
Hey Guys, I am using CJ2M plc and all I want to do is read some parameters from MURR IO-Link connected to Master block. I have all the information required to read the data and I am also able to do that with the network configurator but having hard time doing it with PLC instructions. I have attached the image of how my network configurator file looks like. It has details related to service number, class id, instance id, attribute id and data. I have tried using EGATR, CMND and EXPLT instructions but have no success reading data from the MURR block. It will be really appreciated if some one can help me find out where I am missing something in PLC to implement any of this instructions. -
Hello, I am a beginner in PLC world trying to find my way through LADDER programming, ST, protocols etc etc and I am slowly getting the hang on it but now I have come accross a troublesome implementation. We have 3 Robotic Cells in my plant each of them consisting of a Fanuc robot communicating via Ethernet IP protocol to NX1P2 PLC controller. The setup of communications is implemented and working as intended but I want to use explicit messaging to manipulate certain Robot Position Registers, Registers and string Registers. I have the needed Fanuc documentation and Omron documentation but I am a little lost. Are there any guidelines I could use to start ?

Hello I have a SLC5/05 and a Microscan MV40 smart camera which receives commands to a TCP port. Is there a way the LSC 5/05 can send a command to the camera using the MSG instruction or any other instruction? I would appreciate any advice

I/O Messaging (Class 1, Producer/Consumer) between PLC and PC?
LGreen posted a topic in Allen Bradley / Rockwell Automation
I currently use custom PC-based control software that retrieves data from PLCs using explicit messaging, but I'd like to convert this to implicit messaging, to take advantage the fast data exchange. PLC programming isn't my strong suit, so I've started by getting two ControlLogix PLCs exchanging information via implicit messaging (producer/consumer) -- I was hoping to find enough information to extend this to a PC communicating with the PLC, but so far haven't had any luck. Is it even possible to configure PC based software to exchange implicit messages with a PLC? At an RPI of 2ms? Thanks in advance!
