The μPAC-7186EX-SM 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-SM, you can choose one of them to expand hardware features.

Using the VxComm technology, PC can create virtual COM ports to map the RS-232, RS-485 of the μPAC-7186EX-SM. 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-SM. That is to say, the original software developed for the serial devices can access the serial devices via the Ethernet/Internet without any modification.

Each PC can control up to 256 COM ports (including real COM ports). Using the I/O expansion board, each μPAC-7186EX-SM can have up to 8 COM ports.

Using the Modbus firmware, μPAC-7186EX-SM 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-SM using the SDK (Xserver, Modbus library) provided by ICPDAS.

Ethernet Protocols
TCP, UDP, IP, ICMP, ARP

Support Web Configuration
μPAC-7186E-SM has a built-in web server for configuration. You can use standard web browsers (such as IE, Netscape, Firefox,..etc) to configure its Ethernet and COM ports configurations.

Remote Configuration/Maintenance
μPAC-7186EX-SM can be operated via the Ethernet (TCP/IP or UDP) or RS-232, to allow tasks such as downloading programs, configuration, updating the MiniOS7, etc.

Built-in watchdog timer (WDT)
μPAC-7186EX-SM include an internal watchdog timer (WDT). The watchdog timer will trigger a system reset if the main program fails or neglects to regularly service the watchdog. The intention is to bring the system back from the hung state into normal operation.
