Hi, this has been introduced with a PR we've made to implement the ability to connect to the PLC by using TSAP instead of Rack/Slot. The Buffer.from() is only available in NodeJS versions greater than 6.x. I've created a PR to fix this on plcpeople/nodeS7#34. Meanwhile, if possible, you can update your NodeJS version, and the issue won't happen

This was fixed upstream, going to close the issue
