Recently I downloaded EtherNetIP toolkit and I do not know how to use. I have to read and to write values into the point I/O Allen Bradley to control some devices from PC to point I/O. It will be useful if you can help me with some examples. I used Get Atributte Single.vi but I do not know What are Class, Instance and atributte inputs in VI. For example a input in the point I/O is a emergency stop and I need to monitor this input from PC, but I do not how to use the tookit. Another example is I have to active some actuator (output point I/O) from PC. I appreciate you can give me information. Thank you.

Hi Guys, I'm with a trouble here. Recently we started to get our outdated temperature test cabinet to work, and the best way is to upgrade our PLC. But there cames 2 problems, the biggest is the budget, we do not have any money so we have to work with what we already have, and the second, i'm intern here and there is no one from automation to guide or help me. Now lets face the problem. PLC Allen Bradley micrologix 1100 cards: 1762-IQ16 and 1762-IQ8W6 My first thought is to use Labview to control the PLC, as HMI and data-logger without OPC server to simplify the instalation and cost. The communication: this is really where the problems begin. It will be done through Ethernet. I could not manage Ethernet/IP driver to work, nor pcc or CIP message... which is the best way to communicate? CIP Message, OPC, or any other i do not know? Do you guys see any problems to make a dataloger without OPC? Some things I have tryed Implementation of Common industrial Protocol (CIP) via EtherNet [EtherNet/IP (CIP)] https://lavag.org/topic/6104-industrial-ethernet-ethernetip/?page=1 Ethernet/IP Driver for Micrologix 1100 https://decibel.ni.com/content/docs/DOC-13024 EtherNet/IP Driver for Industrial Communication https://decibel.ni.com/content/docs/DOC-4065 Thanks for any help Ricardo PS.
