Why is Ada not used on industrial programmable logic controllers (PLC) platforms?

In the IEC 61131-3 standard, the language 'structured text' is defined. The language looks like the poor man's Ada.

I have not worked with structured text, but with SCL (Structured Contol Language) for Siemens S7-300 / 400/1200/1500. It looks like there are elements of Ada in it.

Should industrial programs not be Ada's wheelhouse?
