Controlling a Meca500 robot over ehternet

[wjreeve]

I have almost no experience with programming PLCs, I am still waiting for my Unitronics PLC to be delivered,

I have taken on a new project to control a Mecademic Meca500 industrial robot using the Unitronics stand alone PLC via ethernet,

Although I do not have the PLC, I do have the Meca500 operating via its web interface,

As a newbie I need guidance on creating the needed communication settings within the UniLogic software,

This will be a quite a challenge for your first PLC project.

Start by downloading UniLogic and the separate example programs collection. 

Watch the UniLogic training videos at

https://www.youtube.com/c/UnitronicsProgrammablecontrollers/videos

Post a link to as much information as you can about the robot's communication protocol and interface type.

Take the leap and start to build a UniLogic program based on what you understand.  When you run into a wall, post the program with your questions.

If I understand correctly then since the Meca500  receives communications using null-terminated ASCII strings over TCP/IP 

From what I read the first step appears to be create a Struct type of ASCII String??

[Joe Tauser]

That sounds reasonable.  In UniLogic we can stuff a string with whatever we want, and then pump it out Ethernet port either as a TCP Server, TCP Client, or as a UDP packet.  But we need to know the details of what we're trying to do.
