Yup, ladder logic is still around and still used in industrial control system/heavy machinary PLCs (programmable logic controllers). Codesys (https://www.codesys.com/ https://www.codesys.com/) supports it and will work with a bunch of PLC products (e.g. products from IFM or STW), and I think I've seen it in Siemens PLCs as well. You'd be surprised how often it's still used by mechanical/electrical engineers without any programming background to hack something together... And then eventually ends up in production.
