Communication issues with electro-hydraulic actuators in 100,000-liter storage tanks
Thread Content
The root valve of the 100,000 cubic meter crude oil storage tank (used for emergency shutdown) sends relevant signals such as its status via communication to the SCADA system, while the ESD interlock signals are transmitted via hardwired connections to the SIS； The communication signals that enter the SCADA system first need to reach the valve controllers. I would like to ask my colleagues in the industry: how many communication loops can each valve controller support, and how many electro-hydraulic valves (electric valves) can each loop handle? Please coach, thank you
Look at the communication protocols; there are so many Ethernet protocols
