ICP DAS Release Stable and Cost-effective Data Acquisition Auto-Report System?
■ Please refer to Section 2 and 3 for VC++ 6.0 demo program.
■ Please refer to Section 2 and 4 for VB 6.0 demo program.
■ Please refer to Section 6 for more information about Ethernet security.
■ Many applications need to monitor/collect large amount of I/O and acquisition data distributed in wide-spread location for safety and management. The usual way to implement this is to apply one or couples of central PC/Server to poll (request one by one in turn) every PAC/PLC periodically in every spread location. This generates three disadvantages.
◆The CPU loading of the central PC/Server will become too heavy. That is because it must request every distributed local PAC one by one in turn periodically. So the result is the PC/Server becoming un-effective.
◆The second one is when the amount of local PACs is a little more or large, the PC/Server can not handle emergency events (because it request PAC in turn).
◆Every local PAC should setup a fixed Internet IP address for the PC/Server to request them. This waste money and Internet resource a lot.
■ICP DAS ISaGRAF PACs I-7188EG, I-8437-80, and I-8837-80 support Auto-report data acquisition and I/O data to the remote Internet PC/Sever via UDP/IP protocol. They can be setup to report periodically and report at any time when emergency event happens. Moreover, at any time, the PC/Server can send command to the local PAC if necessary. For example, the time synchronization. This feature is very useful in the below three applications.
■ Useful Applications:
◆ Distributed energy monitoring/management system, like electric power, gas, oil, water dam, etc.
◆ Distributed facility safety monitoring/management system, like elevator, building, stock room, etc.
◆ Other possible distributed data acquisition system.
