56.1 The communication protocol
used
(1) S7 communication protocol, PDAServer reads real-time data based on PLC variable addresses. (2) Profinet protocol is used by PDAServer to collect signals that require high-speed acquisition. (3) UDP protocol, standard Ethernet protocol. The above three communication protocols are supported by both PLC and PDAServer. 56.2 Scheme of 1 set of PDA system
for each furnace area
Add one set of PDA high-speed data acquisition and analysis system to each area, as shown in Figure 1. (1) The advantage of this solution is that each system is relatively independent, and maintenance and power outages do not affect each other. The data traffic of the backbone Ethernet network will not increase significantly. (2) The PDA system adopts Ethernet communication method, Profinet and UDP protocol. (3) One set of 10000 point PDA system in LF furnace area. (4) One set of PDA system with 10000 points in the converter area. (5) One set of PDA system with 10000 points in RH furnace area. (6) 3 sets of PDA systems, slightly higher cost, but the high-frequency Ethernet data flow in each area is limited to the local network. (7) This PDA system has a high cost performance ratio, using multiple solutions, and the cost increase is not significant. (8) Any computer connected to L1 Ethernet can perform online and offline data analysis.
Figure 1 Scheme of One PDA System for Each Furnace Area 56.3 The plan of sharing one PDA
system among three furnace areas
Three furnace areas share one set of PDA high-speed data acquisition and analysis system, as shown in Figure 2. (1) The PDA system adopts Ethernet communication method, Profinet and UDP protocol. (2) One set of PDA system with 30000 points is installed in the LF furnace area, converter area, and RH furnace area. (3) Using one PDA system, the cost is slightly lower, but the high-frequency Ethernet data streams in each area need to pass through the L1 central switch, resulting in a higher amount of high-frequency data streams in the backbone network. (4) Any computer connected to L1 Ethernet can perform online and offline data analysis.
