1. If local controller is I-7188EG, the price is much cost-effective compared with other PLC / PAC if they have similar solution .
(ICP DAS I-7188EG, I-8437-80, I-8837-80, W-8347, W-8747 all support this feature)
2. The distributed local controller doesn't need a fixed Internet IP. There is no limitation of the distance between the local controller and the central PC / Server, 100 meters, 1 kilo-meter, ˇK , 10000 kilo-meters are all possible.
3. Provides 4-Level Internet security protection.
Level 1: Controller do auto-report only if it wish do . Controller can be programmed to refuse any communication data coming from Internet normally. The controller can be designed only accept one valid command when it auto-report data to the PC / Server, after that it can refuse any data again.
Level 2: ˇ§Security Passwordˇ¨ . Every delivered data between local controller and PC / Server all add a ˇ§Security Passwordˇ¨ protection.
Level 3: IP protection. Controller can be programmed to accept data only coming from one or couples of selected Internet IP address.
Level 4: Programmer can design his own security protection in both controller and the PC / Server.
4. Local controller will automatically report its acquisition and I/O data to remote PC / Server. It can report periodically and report when an emergency event triggered. Moreover, at any time, the PC / Server can send command to the local controller if necessary. For example, the time synchronization command.
5. ICP DAS ISaGRAF controllers support various I/O modules, such as I-7000 series, I-87K series remote I/O. Also support Modbus RTU devices created by others, like Modbus power meters, Modbus inverters, modbus temperature controllers ...
6 Controllers support ISaGRAF with IEC61131-3 PLC standard, which provides Ladder Diagram, Structure Text, Function Block, IL , SFC and Flow Chart PLC languages. Easy use and easy programming.
7. ICP DAS provides VC++6.0 and VB6.0 and VB.net 2005 sample program which can run in PC / Server. And also provides ISaGRAF sample program for running in I-7188EG, I-8437-80, I-8837-80, W-8347, W-8747 controllers. Please visit www.icpdas.com ˇV FAQ ˇV Software ˇV ISaGRAF ˇV 065 .
