OPTO22由工程师于1974年创立，OPTO22产品设计用于非专有通信标准，如以太网和互联网协议（IP）。开放标准和商用技术降低了自动化成本，并在需要时开放数据。

The SNAP-PAC-R1 programmable automation controller provides control, communication, and I/O processing in a compact, rack-mounted package. A versatile controller, the SNAP-PAC-R1 is:
fully integrated with PAC Project software, SNAP PAC brains, and SNAP I/O modules;
compatible with groov EPIC, either as a SNAP PAC R-series I/O unit to a groov EPIC or to control groov EPIC I/O units (requires PAC Control R10.0a or higher); and
can be used as a remote Ethernet I/O unit to custom control applications running on controllers or PCs.
Used with the freely available PAC Project Basic software suite (or PAC Project Professional, purchased separately), the Ethernet-based SNAP-PAC-R1 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-R1 can provide complete cell control on its own rack with I/O modules. It can also control SNAP I/O and groov EPIC I/O units simultaneously for a larger system. Or the R1 can be used in a more extensive distributed control system as a remote I/O unit controlled by a groov EPIC processor or a SNAP PAC S-series controller. It can even be used as intelligent remote I/O for Allen-Bradley Logix PLC systems, such as ControlLogix and MicroLogix.
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 direct connection to serial devices or for PPP (Point-to-Point Protocol) communication over a modem.
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 (strategies). You create and debug the strategy on your computer and then download it to the R1, where it runs independently. (Processor and memory resources—which affect control application performance—may vary; for more information, see the memory and processor specifications in the Specifications table.)
Remote I/O: The SNAP-PAC-R1 supports OptoMMP, Modbus, and EtherNet/IP protocols. For tasks like network addressing and protocol configuration, you can use the freely available PAC Manager tool to configure the R1 over an Ethernet network.
REST API & Node-RED: Developers can securely access PAC Control strategy tags using the built-in HTTP/HTTPS server and RESTful API, with data delivered in JSON format. For complete API documentation and steps for getting started, see developer.opto22.com. In addition, two Opto 22 Node-RED nodes are available. Note that minimum firmware R9.5a and PAC Project R9.5a are required to use the REST API.
HMI: You can build full-featured operator interfaces (HMIs) using the freely available PAC Display Basic (or PAC Display Professional, purchased separately) software, which taps the same tagname database you've already developed in your PAC Control strategy. SNAP PAC R-series controllers are also compatible with Opto 22's groov products and groov View HMI tool.
Communication: Because the SNAP-PAC-R1 is based on the Internet Protocol (IP), the SNAP-PAC-R1 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, 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).
