SNAP-PAC-R2 leírás

The SNAP-PAC-R2 programmable automation controller provides control, communication, and I/O processing in a compact, rack-mounted package. One of four components of the SNAP PAC System, the SNAP-PAC-R2 is fully integrated with PAC Project software, SNAP PAC brains, and SNAP I/O modules. Used with the included PAC Project Basic software suite (or PAC Project Professional, purchased separately), the Ethernet-based SNAP-PAC-R2 can handle almost all your industrial control, remote monitoring, and data acquisition needs. System Architecture This intelligent, flexible PAC can be used in several ways. The SNAP-PAC-R2 can provide complete cell control on its own rack with I/O modules. It can also control SNAP PAC I/O units at the same time for a larger system. Or the R2 can be used in a more extensive distributed control system as an I/O unit controlled by a SNAP PAC S-series standalone controller. Networking Two independent, 10/100 Mbps Ethernet network interfaces are included on each SNAP-PAC-R2. These interfaces have separate IP addresses and can be used to segment the control network from the company network or to provide Ethernet link redundancy in case of link failure or maintenance. In addition, the controller has an RS-232 serial port with hardware handshaking, which can be used for PPP (Point-to-Point Protocol) communication over a modem or for direct connection to serial devices. Programming and Protocols The SNAP-PAC-R2 is programmed using the included PAC Control software. PAC Control is a flowchart-based tool for developing control applications, or strategies. You create and debug the strategy on your computer and then download it to the R2, where it runs independently. The controller has 16 MB of RAM and can run up to 16 PAC Control flowcharts at once (many more can be included in the strategy). You can build full-featured operator interfaces (HMIs) using the included PAC Display software, which taps the same tagname database you've already developed in PAC Control. In addition to control, the SNAP-PAC-R2 provides communication. Because it is based on the Internet Protocol (IP), the SNAP-PAC-R2 can communicate simultaneously using several different protocols, including TCP/IP, EtherNet/IP, PPP, Modbus/TCP, SNMP for network management, SMTP for emailing, and OptoMMP, the open memory-mapped protocol used by all Opto 22 Ethernet-based devices. I/O Processing The controller mounts on a SNAP PAC mounting rack with up to 4, 8, 12, or 16 digital, analog, serial, and special-purpose I/O modules. Choose the modules needed for your application from the extensive line of SNAP I/O modules. * Analog features include thermocouple linearization, minimum/maximum values, offset and gain calibration, scaling, TPO (time-proportional output), output clamping, filter weight, ramping, totalizing, and watchdog timer. The SNAP-PAC-R2 also offers up to 96 PID loops. * Digital features are simplified on the SNAP-PAC-R2. Digital features include status, latching, watchdog timer, TPO, totalizing, and pulse generation. If you need a Factory Mutual-approved version, see the SNAP-PAC-R2-FM. For high-speed digital features, see the SNAP-PAC-R1. To compare features on the R1 and the R2, see the SNAP PAC Controller and Brain Comparison Chart.
