Anyone heard of these "Barth" plc's

Just saw these in the Radionics catalog, seems a "nice" toy with free software.
Anyone used them before ?

Never heard of them, looks like a nice little package but I wouldn't use one due to it's obscurity.

The BARTH PLCs are better known in Germany. We have served several applications with both STG-500 and STG-600 using the graphical micon-L software.
These tiny gadgets performes very well and they are also well engineered and designed. Our focus lies on battery powered applications in 12 and 24 V systems.

For the same money you can buy a Click PLC with similar I/O.
Even the most basic Click has 2 com ports and led indicators to show status of the I/O.
Free software too.
To me those Barth units are overpriced by 500%.

...similar price but not really a comparable product. The BARTH units are fully sealed (PU potting) with extremly low current consumption of about 2mA in run mode, I think. In addition you also have to pay for the small form factor..

What communication protocols doest it support?

plc-user · May 18, 2015

I don't know for sure which protocols are supported by the STGs RS232 interface. It's made for stand-alone appications especially.
