The purpose of this article is to provide a step by step directions for the development of the built-in Modbus driver settings in the SCADA system WinCC OA.
Unfortunately, the basic course, this connection is not checked and do not give step by step instructions, so I eliminate this gap.
Step by step instructions for connecting a standard station WinCC OA for Modbus TCP protocol. Use popular simulator Modbus TCP Modbus Tools protocol (Download)
-
Must be pre-installed 64-bit operating system, or the key demo version Wincc OA (v3.14 or later)
-
Download the link above and install ModbusPollSetup64Bit.exe and ModbusSlaveSetup64Bit.exe. Install these components to simulate data flow (sending-receiving telegrams) on the Modbus TCP protocol
-
First run Modbus Slave (telegram generation) with the settings as shown in the figures, allowing work on the home network (upper tick)
