I want to communicate with a MiR robot using REST API. I run successful tests using Postman software on a Windows computer. But when I try to send the same request from Simatic S7-1500 PLC using TSEND_C and TREC_C the response is always "HTTP/1.1 404 NOT FOUND" . Anybody with a success storiy on using S7-1200/1500 PLC as a REST API client?
