μPAC-7186EX-MTCP

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

Features of default Modbus firmware
When you buy an μPAC-7186EX-MTCP controller, it already has the default Modbus firmware installed in Flash memory. The default firmware has the follows features:

• Converters single Modbus/TCP to multi Modbus/RTU
  The μPAC-7186EX-MTCP is a Modbus/TCP gateway. It can easily upgrade many Modbus/RTU devices to have Ethernet communication ability.
• Supports VxComm technique for every COM port of controllers
  If serial devices don't support Modbus/RTU, you can still access these devices. But need to install VxComm driver on host PCs and assign a COM port number to link to the remote COM port (of μPAC-7186EX-MTCP). After that, serial clients can access these remote serial devices via standard RS-232 functions.
• Allowed multi-client (or master) access simultaneously
  Different μPAC-7186EX-MTCP controller supports different client numbers connect to.
• Firmware modifiable
  We provide the Modbus SDK allowing users to develop their custom Modbus firmware.

Modbus SDK ( in C language )
If the default firmware doesn't totally suit your requirement. You can use Modbus SDK to modify the default firmware to add extra functions. The Modbus SDK has below features:

• Supports extra user-defined command protocol (TCP/IP)
  Modbus/TCP protocol supports 2 basic data format (bit and 2-byte integer). It means if clients (or called masters) don't support Modbus/TCP or you need other format data (for example: string of floating value), μPAC-7186EX (with default firmware) cannot communicate with them. Using this feature, you can develop your special command protocol to transfer any format of data.
• Register based programming method (easy to use)
  Modbus library supports 4 internal register tables (iMemory_AI, iMemory_AO, iMemory_DI, iMemory_DO), you can use these to store specific information. When Modbus/TCP clients request to μPAC-7186EX-MTCP, Modbus kernel will response information from these 4 tables.
• Provides user-defined registers
  The 4 internal register tables are all open to users. You need to assign these tables by yourself.
• Can Iink to Modbus/TCP slave devices
  By using function ModbusTCP_Master2Slave(declared in MBTCP_7E.h),the μPAC-7186EX-MTCP can link 8 max . Modbus/TCP device.
• Can link to Modbus/RTU slave devices
  By using function ModbusMaster2Slave (declared in MBTCP_7E.h), Modbus/RTU devices can be easily integrated to internal registers of μPAC-7186EX-MTCP. An μPAC-7186EX-MTCP polling every Modbus/RTU devices and put every necessary information to internal registers. Clients only ask the μPAC-7186EX-MTCP to get all information of Modbus/RTU devices. That reduces loading of Clients.
• Can link to non-Modbus/RTU serial devices
  Some serial devices don't support Modbus/RTU. We provide functions to let μPAC-7186EX-MTCP access serial devices. You can put information to internal registers of it. Thus, the non-Modbus serial devices can also support Modbus/TCP.
• Supports X boards You can choose one suitable Xboard to add on an μPAC-7186EX-MTCP to be on board I/Os.
• Xserver SDK compatible
  Modbus SDK is based on Xserver SDK. To lear more programming skills, you can refer demos of Xserver. To get information of demos of Xserver, please refer to CD:\Napdso\7186e\TCP\Xserver\Xserver.htm
