Question regarding setting up in a local environment #43

Closed halcyon0606 closed 3 years ago

halcyon0606 commented 3 years ago

Hi there,

I am pretty new to Beckhoff related material so please bear with me. So, I recently started using my laptop as a development environment and runtime for TwinCAT and it is in my interest to use the ADS nodes. However, I noted that one of the requirements to using the package is a PLC, in which I do not have and I am actually using my laptop to cyclically run the PLC tasks. I am just wondering whether or not it is still possible to set up the ADS connection even though I do not have a PLC and if so, how would I go about it? Would love to hear more about it, cheers!

Whether the PLC is hardware or the runtime on the computer does not matter. A Beckhoff PLC is just a mini PC under Windows. The process is exactly the same. There are problems within the ADS router that the PLC uses, it is not possible to run several ADS clients on the same IP at the same time. Therefore, the first thing to do is to establish communication on two computers. Alternatively, Twincat and Nodered can be linked to two different network IPs. Please have a look at the closed isssues there you will find everything you need.
