Easy access of environment variables from Python with support for booleans, strings, lists, tuples, integers, floats, and dicts. Use Case If you need environment variables for your settings but need an easy way of using Python objects instead of just strings. For example, if you need a lis...
Working with Integers and Floats Sending and receiving integer and float data is common on PLCs (programmable Logic controllers). To send this data requires a little more work as you need to convert it. The best way of covering this is with examples and below is a screen shot showing how...
