In this way, 3 functions need to be realized, namely, setting the coil and reading the register. If you press Modbus content, you can use the setting coil status and reading the coil status, and the AD and temperature and humidity acquisition need to read the register. According to the requirements of the other party, the settings of P0 and P2 ports need to be read or set bit by bit. The main thing that needs to be realized is the realization of the Modbus RTU communication protocol. STH10 has a ready-made code, and the AD conversion is directly provided by the official program. KEPServerEx V4.0 uses TCP communication, and the one-chip computer uses the serial port RS232 communication, so increase the TCP to RS232 module. One of them is the concentration of C02 collected, and Use SHT10 to obtain temperature and humidity. All OPC client interfaces can connect to KEPServerEX without additional charge.Recently, a customer requested to use STC12C5A60S2 to realize Modbus Rtu protocol and KEPServerEx V4.0 software communication, collect the status of each bit of the P2 port of the single-chip microcomputer, set the status of each bit of the P0 port, and realize the three-way AD conversion. Additional drivers can be licensed on demand as connectivity needs evolve.
The driver handles all proprietary communications between the data source and KEPServerEX KEPServerEX handles all OPC or proprietary client communications between the driver and the client application(s).ĭrivers may be licensed individually or in suites. Memory Types Supported: I, IB, Q, QB, M, MB, R, RB, C, CW, CP, T, TW, TP, H, HW, DWĪ driver is a software component that enables KEPServerEX to meet the communication requirements of a specific device, system, or other data source.Multi-drop RS485 (1 to N), and Peer to Peer RS232 (1 to 1) Supported.This time-saving step instantly makes all of the relevant PLC data available to your OPC client applications. If you are using WindLDR version 4.12 or greater, you will be able to import the tags used in your PLC application directly into KEPServerEX.
The IDEC Serial driver now offers direct integration with the WindLDR programming package. Data integrity is ensured with our extensive error handling. KEPServerEX automatically optimizes your data acquisition based on client demand. The IDEC Serial device driver works in conjunction with KEPServerEX to provide data exchange between OPC clients and Idec serial PLCs.
