I-7188EX/£gPAC-7186EX series programmable Modbus Gateway
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. The Modbus gateway firmware has already been installed in I-7188EX-MTCP and uPAC-7186EX-MTCP units. Therefore, linked with I-7188EX-MTCP or uPAC-7186EX-MTCP, PCs or PLCs can use Modbus/TCP or Modbus/RTU protocol to communicate with I/O modules which use Modbus/RTU protocol and link to any COM port of the gateway.
Besides the gateway functionality, I-7188EX-MTCP and uPAC-7186EX-MTCP units are also c language based programmable controllers that equipped with DOS-like OS (MiniOS7). Users can use C compilers that can create 16 bit executable (*.exe) files to develop a program. After downloading it to the controller, the controller will be able to work stand-alone. There are two free charge version compilers ( Turbo C 2.0 and Turbo C++ 1.01 ),and we suggest users to use the Turbo C++ 1.01.
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. |
