SNAP PAC R-series Automation Controller Ref: SNAP-PAC-R1

System Architecture
This intelligent, flexible PAC can be used in several ways. The SNAP-PAC-R1 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 R1 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-R1. 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-R1 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 R1, 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-R1 provides communication. Because it is based on the Internet Protocol (IP), the SNAP-PAC-R1 can communicate simultaneously using several different protocols, including TCP/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, ramping, TPO, output clamping, filter weight, and watchdog timer. The SNAP-PAC-R1 also offers up to 96 PID loops.
Digital features on 4-channel digital modules include latching, high-speed counting (up to 20 kHz depending on the module), quadrature counting, pulse generation and measurement, TPO, and watchdog timer. Features on high-density digital modules are more limited (see module data sheet for details).

If you don't need full digital features, see the SNAP-PAC-R2. To compare features on the R1 and the R2, see the SNAP PAC Controller and Brain Comparison Chart.

SNAP PAC Learning Centre Ref: SNAP-PACLC

The SNAP PAC Learning Center is a fully functional, complete package of Opto 22 hardware and software that provides everything you need to learn about Opto 22’s SNAP PAC System. The Learning Center includes PAC Project Basic software, a SNAP-PAC-R1 rack-mounted controller, SNAP I/O modules and mounting rack, and a load panel with digital and analog sensors and actuators (switches, LEDs, a temperature probe, a meter, and so on).

The included step-by-step tutorial guides you through the hardware assembly and software installation and gives you hands-on programming experience with the PAC Project software. You will configure I/O points, read and write to those points, create several flowcharts as part of a control strategy, and build a graphical user interface.

Because the SNAP PAC Learning Center consists of the same field-proven, real hardware and software used by Opto 22 customers all over the world, you'll be able to apply not only the knowledge you've learned, but also the actual Learning Center hardware and software in your next automation project.
