I'm happy because these past 2 weeks I have been working to decode and interpret the communication between the LOGO! PLC and a PC. Well ... I finished this work and achieved the following:

-          Ask the status of communication between PC – LOGO! PLC

-          Ask the status of the PLC (The PLC responds RUN/STOP status)

-          Forcing the status of the PLC to RUN mode.

-          Forcing the status of the PLC to STOP mode.

-          Ask the current values (in real-time) of all channels of the PLC:

o   24 digital inputs

o   16 digital outputs

o   8 analog inputs

o   2 analog outputs

o   24 digital marks

o   6 analog marks

o   4 cursors

 

The application developed in LabVIEW performs the main function of communicate the Desktop / Laptop with PLC LOGO! (That is to say link National Instruments with Siemens ... ja ja). The software performs the following functions:

-          Monitors and displays all channels of the LOGO!

-          Choose the communication port.

-          The user can save in a file all the data, each configurable period.

 

I have made many tests with different logic modules, and it has not given any problems.

 

In the image attached, I show you some of the topologies that can be implemented knowing this protocol of communication. I ask you to spread this to engineers/technicians who design and implement these MICRO-AUTOMATION systems, in order to offer this Software applicable to supervisory system or data-logger device.

 

I'm ready to be able to help.

Dear members,

Maybe I am wrong, but... Look, we lost 2 weeks to ask for more details about this job. (LOGO and some "HMI" for it). Ok, everythings works perfect, but who is happy.  Now I understand that this is "private job" and someone works 2 months or 2 year for this result. But this is international forum and in each conference here, some of members, some of experts, has own "applications" that can solved a lot of problems and also give more possibilities. And all of this is personal secret. Nobody here didn't said: I have or I can without details. My idea is, this "example" shown in this way is not serious. Not in this forum. You saw, a lot of questions about this without any result. For me is not necessary to take free place of this forum for some... If you can sell this job - OK, it's your right... but I think no in this way...

And one more question -  why would I use LOGO plus Labview? Couldn't I preffered  S7-200 and Microwin. Or S7-1200...togue

Best regards
