描述：Opto 22"s PAC Project? software suite provides full-featured control and HMI development tools to create your control, monitoring or data acquisition system. PAC Project is easy to use and suitable for projects from equipment management to industrial control. Designed for use with a SNAP PAC R-Series or S-Series programmable automation controller (PAC), PAC Project software is available in two forms: PAC Project Basic? and PAC Project Professional?. Both versions of PAC Project include three powerful applications: * PAC Control?, for Developing Control Software Applications * PAC Display?, for Developing Human-Machine Interface Applications (HMIs) for Technicians and Operators * PAC Manager?, for Configuring and Inspecting Opto 22 Ethernet-Based Controllers and I/O Units PAC Control Software — Software that speaks the same language you do. Plain English. PAC Project Basic is included with SNAP PAC R-Series and S-Series controllers and provides everything you need for most control system projects that don"t require legacy upgrades or complex Ethernet connections. PAC Project Basic can also be used with a legacy SNAP-LCE controller or SNAP Ultimate I/O controller/brain. PAC Project Professional takes full advantage of SNAP PAC controller features, including dual Ethernet interfaces and serial network support and adds OptoOPCServer? for OLE for Process Control (OPC) communication with OPC 2.0 clients. PAC Project Professional also comes with OptoDataLink? database connectivity software. PAC Project Professional adds the power, flexibility, and scalability you need to: * Control Ethernet-Based SNAP I/O? and Serial-Based Mistic I/O Units at the Same Time (Requires SNAP PAC S-Series Controller) * Use Legacy Programming from OptoControl? and OptoDisplay? * Communicate Using Multiple Protocols * Configure Redundant Ethernet Links or a Segmented Control Network PAC Display Software — Software that isn"t hard. PAC Display is the full featured, Human-Machine Interface (HMI) component of the PAC Project Software Suite. It includes alarming, trending, authentication, data encryption and much more. And thanks to its highly intuitive environment, single tagname database, simple point-and-click tools, graphics and symbols, it"s exceptionally easy to get started with and master. We dare you to compare PAC Display against HMIs costing thousands more and think you"ll agree that the power, simplicity and flexibility of PAC Display not only make it easy to use, but easy to choose.
