7 1. INTRODUCTION The DASTEC Corporation MODBUS/TCP Ethernet Communication Interface API allows the user to implement bi-directional communications to exchange data between applications running on a Windows/WinCE-based system with other peer devices supporting the MODBUS/TCP Ethernet protocol. The peer devices can be Modicon devices, other host computers or even other system applications using the API. The MODBUS/TCP Ethernet Communication Interface API enables a system to acts as a client to other Modbus peers, initiating read and write operations on behalf of the system applications. The API also allows the system to emulate a Modicon PLC to respond to read and write requests and thus acts as a virtual PLC to other MODBUS/TCP peers. The MODBUS/TCP Ethernet Communication Interface API is available for different Windows/WinCE-based systems/platforms. This manual serves as the setup manual for only the WinCE platforms sold by Intelligent Instrumentation Inc. (III), which include the EDAS CE and the LanPoint CE. The API s operational details, installation and programming information can be found in the MODBUS/TCP Ethernet Communication Interface API User Manual. This manual provides the following information: Hardware, software and documentation requirements for the MODBUS/TCP Ethernet Communication Interface API software for the. Additional installation and setup instructions for the API software to be used on Intelligent Instrumentation WinCE Platforms.
