BCNet-S7200-S is used for data acquisition of PLC such as Siemens S7-200/SMART S7-200, etc. It is very convenient to build a production management system. The module integrates WiFi function, supports AP mode, STA mode and AP+STA mode, which is very convenient to build a WiFi network, and perform PLC programming, data acquisition and data exchange directly through WiFi. It supports communication with Ethernet interface of S7-200SMART, S7-1200/1500, S7-200/300/400, ModbusTCP master-slave communication and point table detection function. The straight-through type and the bridge type can be dialed for selection. The straight-through nine-pin female port can be connected to Siemens and Proface touch screens and the main station, and the bridge-type nine-pin female port can be connected to the touch screen.
