Maintenance information. The engineering station is an ordinary PC connected to the operator station via Ethernet. A set of WinCC software is also running on the engineering station, configured via DCOM, and also accessing data from WinAC in OPC mode, and certain permissions are higher than on the operator station. Because WinCC industrial configuration software is used on the operator station, it is very convenient for management to obtain production information from this production line. WinCC has a variety of methods for online data exchange.
For example, it can use the client / server mode of WinCC, or the Web browser function of WinCC, etc., to provide multiple options for the networked production management of user plants in the future. A mobile TP170B operation panel is directly connected to the system's PROFIBUS network through the PROFIBUS 3-port connector on the ET200M interface template IM153 on the C or D device. Manually operate any C device or D device on the network so that The commissioning personnel can perform manual commissioning directly on the side of the device.
TP170B integrates the manual debugging screens of all A, C, and D devices on the production line, so one TP170B can complete the manual debugging of all devices. As for the system control software, the control program of B and E devices is completed by its own CPU224. A, C, D device control program is completed by WinAC Slot 412. Among them, the A device has two high-speed counting requirements, which are completed by two FM350-1 high-speed counting templates. There are two pressure PID adjustments in each D device. There are four PID adjustments in the system. In view of the high-speed instruction execution speed of Slot 412, the S7 software PID function block can fully meet the requirements.
An important part of the wire knitting machine control software is to complete the user's multiple process selection requirements. As shown in Figure 1, textile mills can set up production lines at will according to the technological requirements of their products. For example, you can purchase only one set of A, B, C, and D equipment and several E equipment to form a production line; or you can purchase one set of A, B, and C equipment, two sets of D equipment, and several E equipment to form one production line; or Buy 1 set of A equipment, 2 sets of B, C, and D equipment each.
