SNAP-PAC-R1 Controller:

The SNAP-PAC-R1 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-R1 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-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 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. It can even be used as intelligent remote I/O for Allen-Bradley Logix PLC systems, such as ControlLogix and MicroLogix.

SNAP-PAC-R1

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).

REST API: All I/O point and strategy variable data is available for secure access 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 Node-RED nodes are available.

SNAP-PAC-EB1

SNAP-PAC-EB1:

The SNAP-PAC-EB1 brain is an I/O and communications processor for your control system. Designed primarily to work in distributed systems controlled by a SNAP PAC S-series or R-series controller, the SNAP-PAC-EB1 can also be used as intelligent remote I/O with Allen-Bradley industrial PLC systems. The SNAP-PAC-EB1 provides local intelligence that frees the controller (PAC or PLC) for supervisory tasks.

As an I/O processor, the SNAP PAC brain independently handles functions such as latching, counting, thermocouple linearization, watchdog timers, and PID loop control. These functions continue to work on the brain even if communication with the controller is lost.

The SNAP-PAC-EB1 brain supports all the SNAP I/O analog, digital, and serial input and output modules available on the Opto 22 website. These modules can all be mixed on the same mounting rack and placed in any position on the rack. The brain and modules mount on a SNAP PAC rack, which holds up to 4, 8, 12, or 16 modules.

NOTE: In order to use Opto 22 serial modules with an EB2 brain, the I/O should be controlled by a SNAP PAC controller running a PAC Control strategy.

In addition to I/O processing, the SNAP PAC brain communicates over a standard 10/100 Mbps Ethernet network. The brain is equipped with two switched Ethernet network interfaces. Because these interfaces share a single IP address and act just like an Ethernet switch, SNAP PAC brains can be installed in a multi-drop (daisy-chain) configuration, extending the control network without the added expense of additional Ethernet network hardware. SNAP PAC brains can also be installed in a star configuration using standard, off-the-shelf Ethernet network components.

The SNAP-PAC-EB1 brain supports communication using multiple protocols running simultaneously over Ethernet. Most customers use the PAC Project software suite for control, monitoring, and data acquisition. At the same time, you can communicate using other methods, including EtherNet/IP, Modbus/TCP, SNMP, SMTP, FTP, and OptoMMP. Communication with OPC 2.0-compliant clients is available through OptoOPCServer.

The SNAP-PAC-EB1 brain offers high-speed digital functions, including high-speed counting (up to 20 KHz, depending on the module), quadrature counting, pulse generation and measurement, and TPO (time-proportional output). Pulse generation and measurement require PAC Control and a SNAP PAC controller, or using the brain with Allen-Bradley PLC systems. For a complete list of features and specifications, see form #1689, the SNAP PAC Brains Data Sheet, under the Docs & Downloads tab.

The SNAP-PAC-EB2 brain provides basic digital functions but does not offer high-speed digital functions; if you need high-speed counting (up to 20 KHz depending on the module), quadrature counting, pulse measurement, and frequency and period measurement, choose the SNAP-PAC-EB1 brain instead. For a complete list of features and specifications, see form #1689, the SNAP PAC Brains Data Sheet, under the Docs & Downloads tab.

NOTE: If you need a Factory Mutual-approved version of this brain, see the SNAP-PAC-EB2-FM.

SNAP-Relay Modules

The SNAP Reed Relay modules use reed relays and do not provide optical isolation. Current rating depends on the voltage the module is used with. These modules were designed for a very low-voltage DC load that is purely resistive (no inrush current). Because of their low 10 VA rating, these modules cannot be used with inductive or capacitive loads (even very small loads) nor 120 VAC.

SNAP-PAC-R2

SNAP-PAC-R2 Controller:

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. 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-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).

REST API: All I/O point and strategy variable data is available for secure access using the built-in 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 Node-RED nodes are available. Note that minimum firmware R9.5a and PAC Project R9.5a are required to use the REST API.

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. OR take advantage of Opto 22's groov to quickly build and view HMIs you can use on virtually any computer, tablet, or smartphone—any screen size, from any manufacturer—using just a modern web browser (like Firefox or Chrome). Learn more about groov.

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 4812, 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.
