The μPAC-7186EX is a palm-size programmable automation controller that with Ethernet, RS-232, RS-485 communication. ICPDAS provide easy-to-use software development tool kits (Xserver, VxComm, Modbus libraries). Users can use them to easily integrate serial devices to have Ethernet/Internet communication ability and through the standard Modbus protocol to communicate with SCADA software (Indusoft, ISaGARF, DasyLab, Trace Mode, Citect, iFix, etc.).

For the hardware, it also supports an I/O expansion bus. The I/O expansion bus can be used to implement various I/O functions such as D/I, D/O, A/D, D/A, Timer/Counter, UART, flash memory, battery backup SRAM, ASIC key & other I/O functions. Nearly all kinds of I/O functions can be implemented by this bus but the bus can support only one board. There are more than 50 boards available for μPAC-7186EX, you can choose one of them to expand hardware features.

Features

Support for Virtual COM technology
Using the VxComm technology, PC can create virtual COM ports to map the RS-232, RS-485 of theμPAC-7186EX. The software running on the PC can operate the virtual COM ports like a standard COM port to access the serial devices connect to the μPAC-7186EX. That is to say, the original software developed for the serial devices can access the serial devices via the Ethernet/Internet without any modification.

Support Modbus Protocol
Using the Modbus firmware, μPAC-7186EX offers following Modbus features:

• Modbus/TCP/RTU/ASCII slave
• Modbus/TCP/RTU/ASCII master
• Gateway for Modbus/TCP to Modbus/RTU

Easy-to-use software development tool kits (using C language)
If the default firmware does not totally fulfill the user's application needs, custom firmware can be developed for μPAC-7186EX using the SDK (Xserver, Modbus library) provided by ICPDAS.
