What is the execution sequence in FCS in CS3000?
Thread Content
There are sequence control tables, control charts, etc. in FCS. What is the execution sequence of these in FCS?
Just like the execution sequence of PLC is input acquisition------>operation---------->output. What is the execution sequence of FCS? Some instruments have high-speed cycles and some low-speed cycles. What are the differences in the execution of FCS?
Sweat, I really don’t know. Let me ask you and I will reply to you tomorrow. I only know that the processing cycle of FCS is in units of 50ms. It can be adjusted according to the cycle of the instrument to save resources and improve system efficiency. As for what the difference is, I really don’t know.
Thank you! I have another question. I use two PIDs in series. The main SET is connected to the S10 terminal of SW-33. S11 and S12 of SW-33 are connected to two DESTs respectively. The main IN is connected to the external terminal; the IN of the slave PID is connected to the SET of the external master. The SET is connected to the OUT terminal of the main PID. The OUT terminal of the slave PID is connected to the external terminal. With such a control loop, why does the main PID always display IMAN (manual initialization) during simulation?
