The μPAC-7186EX-SM is a palm-size programmable automation controller (PAC) that has Ethernet, RS-232, and RS-485 communication capabilities. ICP DAS USA provides easy-to-use software development tool kits (Xserver, VxComm, Modbus libraries). With easy integration to serial devices, this device has the ability connect through standard Modbus protocol to communicate with SCADA software (Indusoft, ISaGARF, DasyLab, Trace Mode, Citect, iFix, etc.).
The hardware 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-SM, you can choose one of them to expand hardware features.
