Modbus/TCP Embedded Controller (Ethernet enables Modbus commands to run over TCP/IP)
Modbus Firmware Features: ● Supports VxComm technique for every COM port of controllers ● Allowed multi-client (or master) access simultaneously ● Firmware modifiable
Modbus SDK (in C language) Features: ● Supports extra user-defined command protocol (TCP/IP) ● Register based programming method (easy to use) ● Provides user-defined registers ● Can link to Modbus/TCP slave devices ● Can link to Modbus/RTU slave devices ● Can link to non-Modbus/RTU serial devices ● Xserver SDK compatible
Modbus is a highly well-known protocol in industrial manufacturing and environment monitoring fields. It suits master-slave or query-response distributed I/O applications.
With the software development toolkits provided by ICP DAS, users can customize the firmware. The SDK provides rich functions for Modbus communication, such as Modbus/TCP master/slave, Modbus/RTU master/salve, Modbus/ASCII master, etc. Furthermore, by calling relative COM port functions (such as IsCom, ReadCom, ToCom.,etc), you can convert other non-standard protocol to Modbu/TCP or Modbus/RTU. That is to say, the controller can be a protocol converter, too.
