r/controlengineering

Hello all . I have recently changed company’s from one automotive manufacturer to another . I will be taking over Responsibility for PLC programming and maintenance for the whole plant after tomorrow when the current engineer moves to a new plant . So I have been taking time to learn this plants standards and poking around the saftey logic to see what I will be dealing with and I found some concerning things . For one thing non of the processors are saftey locked or have a signature ( Allen Bradley) , so I’m going to bring that up as I feel like that is a non negotiable when you have humans working on a production line especially with robots. Second non of the robots ( Fanuc ) have DCS fence lines to prevent the robot from driving through the fence or pinning a programmer. I was understanding this was a ISO requirement. But I’m not 100% on that and I don’t want to spend my own money to buy the manual . Does anyone have any insight into this ? I brought this issue up to the corporate controls manager and was told “ we don’t use DCS fence lines, I won’t use that garbage “ . And just to be clear I don’t mean instead of a physical fence I mean along with it . Thank you all for the help in advance
