power module; If the light load output is not stable, (even flying car) fault is generally in the motor feedback circuit. Because the customer used a large motor on site, up to hundreds of kilowatts, when contacted by phone, I confirmed that the motor carbon brush did not ignite, and the fault machine had been in use, after the fault occurred, no matter light load or heavy load, armature current fluctuated greatly.
1 DCS is a “decentralized control system”, and PLC (programmable controller) is just a control “device”, the two is the difference between “system” and “device”. The system can realize the function and coordination of any device,PLC device only realizes the function of this unit.\
2. In terms of network,DCS network is the central nervous system of the whole system, it is a safe and reliable double redundancy high-speed communication network, the system’s expansion and openness is better. And PLC because basically all work for the individual, its in communication with other PLC or upper computer, the network form is basically a single network structure, network protocol is often inconsistent with international standards. In network security, PLC does not have very good protection measures. We use dual redundancy of power supply,CPU and network.
3. DCS overall consideration of the scheme, the operator station has the function of the engineer station, station and station in the operation of the program after installation is a close association between any
