Sir, kya plc main bhi server hota hai jaisa ki aapne dcs main bataya hai? Aapne dcs ko fast bataya as compared to plc .lekin ESD ( emergency shutdown system) main plc use krte hain kyon ?
No, plc doesn't have a server. No, esd doesn't need to have and Yes if you want any special equipment to perform freely, then you can take it the system into plc
No, plc doesn't have a server. Plc can be used for a single application like ESD because the controller has to perform the limited function, but It doesn't mean DCS can't do. DCS can handle so many critical operations, even whole plant are loaded at DCS.
My point of view DCS mai jo bhi logic bnana hai wo 1 software se hota hai aur SCADA ka development b wohi software se hona chahiye, jb ki PLC mai alg hote hai
