As part of the Opto 22 SNAP PAC System, one of these compact, industrially hardened controllers can handle multiple control, automation, and data acquisition tasks involving digital and analog control, serial string handling, PID, and enterprise and Internet connectivity. Connecting to Opto 22 serial- and Ethernet-based I/O systems, a SNAP PAC S-series controller runs control programs written in Opto 22's PAC ControlTM software to monitor and control a wide range of devices and equipment. SNAP PAC S-series controllers are well suited to original equipment manufacturers (OEMs), system integrators, and end-users in process control, discrete manufacturing, or hybrid industries and applications. SNAP PAC S-series controllers include a RESTful API (representational state transfer application program interface), so you can use the language of your choice to securely access controller tag data and use it for business purposes. SNAP-PAC-S2 controller SNAP PAC S-series controllers include two 10/100 Mbps Ethernet interfaces for networking through an Ethernet switch to Ethernet hosts, as well as SNAP PAC brains and I/O, which provide local intelligence and the connections to digital and analog sensors and actuators as well as serial devices. These independent Ethernet ports have separate IP addresses that can be used with PAC ProjectTM Professional software to set up redundant network links to safeguard the availability and reliability of an I/O system, or to segment a control system's network from the enterprise LAN.

DATA SHEET Form 1584-170720 PAGE 2 Wired+Wireless Communication purpose serial communication. For the default configuration settings of these ports, see form 1592, SNAP PAC S-series User's Guide. SNAP-PAC-S1-W and SNAP-PAC-S2W controllers add wireless capability to communications. In addition to the two wired network interfaces, these models have a wireless network interface as well, so each PAC has a total of three separate IP addresses--two wired and one wireless. Wired+Wireless PACs can be used wirelessly or on a wired network, or both at once. For flexibility in designing your wireless network, wireless communication includes support for 802.11a, b, and g standards. Wired+Wireless PACs can be used with a variety of wireless switches and other infrastructure hardware. For the best security, the 802.11i WPA2/AES standard is supported, while older WPA and WEP security standards are included for backwards compatibility. Just like a laptop computer with a wireless connection, all functionality remains the same whether the Wired+Wireless PAC is used wirelessly or as part of a wired network. Supported protocols remain the same. Control programs run the same on both networks without reprogramming. A Wired+Wireless S-series PAC can communicate with both wired and wireless SNAP PAC I/O units. (See "I/O Units Supported" on page 4 for details.) If desired, the PAC can segment a wireless network from a wired one. Serial Communication SNAP PAC S-series controllers provide RS-232 and RS-485 communication as follows: The SNAP-PAC-S1 and SNAP-PAC-S1-FM have two RS-232 serial ports that support general-purpose communication with serial devices; you can send and receive data from one or two serial devices connected directly to the controller. Port 0 can be connected to a modem using PPP (Point-to-Point Protocol). These controllers also have one pluggable two-wire RS-485 port that can be used for SNAP PAC or mistic serial I/O units. For additional serial interfaces, you can add one or more SNAP serial communication modules on SNAP PAC racks connected to the controller. Configured as RS-232, the ports support remote serial device communication, and any one of the ports can be configured as a PPP modem connection for creating a TCP/IP network over PSTN (Public Switched Telephone Network) lines. Configured as RS-485, the serial ports connect to legacy Opto 22 misticTM I/O units, including the serial B3000 brain and remote mistic bricks, and to SNAP PAC SB-series serial brains. For additional serial host interfaces, you can add one or more SNAP serial communication modules on attached SNAP Ethernet-based I/O units. Controller Redundancy Two identical SNAP PAC S-series controllers can be used to form a redundant system, where one controller actively runs the control program and the other is ready to take over immediately if the first one should fail. Besides two identical PACs, a redundant system requires PAC Professional 9.0 or newer (see "Software," below), and the SNAP PAC Redundancy Option Kit. For more information, see form 1901, SNAP PAC Redundancy Option Kit Data Sheet, and form 1831, SNAP PAC System Redundancy User's Guide, both available on our website. Backward Compatibility S-series controllers have RS-485 serial interfaces for connecting to Opto 22's legacy mistic I/O units. The SNAP-PAC-S1 and SNAP-PAC-S1FM have one RS-485 port, and the SNAP-PAC-S2 can be configured with up to four. This connectivity with legacy serial-based I/O systems, combined with PAC Control Professional's ability to import control programs (or strategies) written in OptoControlTM software, provides a migration path to integrate older Opto 22 I/O systems into modern control hardware running on Ethernet networks. For detailed information on updating control strategies and integrating legacy control hardware into modern systems, see form 1692, FactoryFloor to PAC Project Migration Technical Note. The SNAP-PAC-S2 has four serial ports that can each be configured using PAC Manager as either RS-232 or RS-485 (2-wire or 4-wire). These serial ports can be used for I/O or for general- OPTO 22 * 800-321-6786 * 1-951-695-3000 * www.opto22.com * sales@opto22.com (c) 2006-2017 Opto 22. All rights reserved.

DATA SHEET Form 1584-170720 PAGE 3 SOFTWARE SNAP PAC controllers use Opto 22's PAC Project Microsoft(R) Windows(R)-compatible automation software for control programming, human-machine-interface (HMI) development, and OPC and database connectivity. Two versions of PAC Project are available: * PAC Project Basic includes PAC Control for developing control programs, PAC DisplayTM for creating operator interfaces, and PAC ManagerTM configuration software. * PAC Project Professional adds expanded versions of PAC Control and PAC Display, plus a SoftPACTM software-based controller for PC-based control, OptoOPCServerTM software for exchanging data with OPC 2.0-compliant client software applications, and OptoDataLinkTM for exchanging SNAP PAC System data with ODBC-compliant databases. Applications included in the PAC Project software suite are: PAC Control Basic is a graphical, flowchart-based programming tool for machine control and process applications. Using PAC Control, you create, download, and run strategies on a SNAP PAC controller. In addition to flowchart programming with subroutine capability, PAC Control includes a powerful, built-in scripting language based on C and other procedural languages. PAC Control Professional adds capabilities to import OptoControl strategies, to support mistic I/O units, and to use a SNAP PAC controller's independent Ethernet ports to segment communication links. PAC Display Basic is an intuitive HMI package for building operator interfaces, or projects, for communicating with a SNAP PAC controller. PAC Display offers a full-featured HMI including alarming, trending, and a built-in library of 3,000 industrial automation graphics. PAC Display Professional adds the ability to import projects created in OptoDisplay, part of the Opto 22 FactoryFloor(R) software suite, and to use redundant communication links on SNAP PAC controllers. PAC Display Professional can also connect to Ethernet-based FactoryFloor controllers running OptoControl strategies or ioProject controllers running ioControl strategies. SoftPAC is a software-based programmable automation controller (PAC) designed for PC-based control. Programmed just like an Opto 22 hardware PAC, SoftPAC runs your PAC Control strategy independently on an embedded or standalone PC. SoftPAC takes advantage of a PC's speed and file capabilities for applications requiring extended file storage, frequent access to files, math-intensive processes, or a large number of control flowcharts running at the same time. OptoOPCServer (PAC Project Professional only) is a fast, efficient OPC 2.0-compliant server for communicating with many Opto 22 products, including SNAP PAC controllers running PAC Control strategies, SNAP PAC brains, SNAP Ultimate controller/brains, SNAP Ethernet and SNAP Simple brains, and Ethernet-based FactoryFloor controllers running OptoControl strategies. Using OptoOPCServer, you can consolidate data from all these Opto 22 systems into the OPC client software of your choice, such as third-party HMI and data acquisition packages, and custom software applications you create with tools such as Visual C++(R). OptoDataLink (PAC Project Professional only) transparently provides multiple connections for data exchange with popular databases such as Microsoft SQL Server, Microsoft Access, and MySQL. OptoDataLink connects your SNAP PAC system with the tools used for making business decisions, bringing real-time, accurate data to decision makers. PAC Manager is a utility application for assigning IP addresses to SNAP PAC controllers and brains, reading or changing basic controller configuration, upgrading firmware, and inspecting or testing controllers and I/O. Software Availability PAC Project Basic is included with SNAP PAC controllers and is a free download from the Opto 22 website. PAC Project Professional is available for purchase. You can also separately purchase PAC Control Professional, PAC Display Professional, SoftPAC, OptoOPCServer, and OptoDataLink as needed. For additional information, see form 1699, PAC Project Data Sheet. RESTful API Ready for the Industrial Internet of Things (IIoT)? Need to use controller data for business purposes? Your SNAP PAC controller's built-in RESTful application program interface (API) lets you exchange data easily using the architecture of the Internet and the language of your choice. You can query PAC Control strategy tags with HTTPS (Basic Auth) using your favorite programming language--PHP, .NET, Node.js, Python, or others. Tag data from I/O points and controller variables is returned as JSON. You can set up authentication keys with permissions for either readonly or read-write, as necessary for your application. The RESTful API is included in SNAP PAC firmware R9.5a and PAC Project 9.5 (or higher). See developer.opto22.com for complete information.

Enterprise Network PC running PAC Display Professional PC running OptoOPCServer and OptoDataLink This diagram shows multiple Opto 22 SNAP I/O units connected together over an Ethernet network and controlled by a SNAP PAC S-series controller running a control strategy. The controller is also connected to a larger, separate enterprise Ethernet network to provide data to two PCs running Opto 22's PAC Display HMI software and OptoOPCServer. Sitting between the two networks, the SNAP PAC S-series controller isolates I/O and control traffic from the enterprise network, and vice versa. For this system, PAC Display must be configured to access the I/O through the controller rather than directly from the I/O units, since they are on a separate network. Ethernet switch, network #1 If you are using a Wired+Wireless PAC, one of these networks could be a wireless LAN. SNAP PAC S-series controller communicates with host computers through one network interface and controls I/O with other devices through the other interface.

This configuration addresses the concern that an Ethernet network may fail or need maintenance, leaving the PC running OptoOPCServer, the PC running PAC Display, the controller, and the I/O units unable to communicate. In this configuration, if one network goes down, devices can still communicate on the other. Each PC has two network interface cards (NICs), and the SNAP PAC S-series controller and the I/O units (SNAP PAC R-series) have two network interfaces as well.

One is the active controller, while the other acts as a backup, ready to take over should the first one fail. The two controllers you use must be exactly the same part number (for example, two SNAP-PAC-S2 controllers or two SNAP-PAC-S1-W controllers). Controller redundancy requires PAC Project Professional 9.0 or newer and the Redundancy Option Kit, which includes the arbiter and the redundant power switch in this diagram. PAC Redundancy Manager, a software utility for setting up and maintaining the system, is included in PAC Project Pro. One advantage of an Opto 22 redundant system is that it uses standard PACs, standard cabling, and standard I/O. Another advantage is that either controller can act as the active or backup controller; you can switch their roles at any time for maintenance, for example.

SNAP PAC System Developer- and IIoT-ready, the SNAP PAC System connects physical assets to databases and applications using open standards. The SNAP PAC System consists of four integrated components: * SNAP PAC controllers * PAC ProjectTM Software Suite * SNAP PAC brains * SNAP I/OTM PAC Project Basic offers control and HMI tools and is free for download on our website, www.opto22.com. PAC Project Professional, available for separate purchase, adds one SoftPAC software-based controller, OptoOPCServer, OptoDataLink, options for controller redundancy or segmented networking, and support for legacy Opto 22 serial misticTM I/O units. SNAP PAC Brains While SNAP PAC controllers provide central control and data distribution, SNAP PAC brains provide distributed intelligence for I/O processing and communications. Brains offer analog, digital, and serial functions, including thermocouple linearization, local PID loop control, watchdog, totalizing, and much more. SNAP I/O I/O provides the local connection to sensors and equipment. Opto 22 SNAP I/O offers 1 to 32 points of reliable I/O per module. Analog, digital, and serial modules are mixed on one mounting rack and controlled by a SNAP PAC brain or rack-mounted PAC. QUALITY Founded in 1974, Opto 22 has established a worldwide reputation for high-quality products. All are made in the U.S.A. at our manufacturing facility in Temecula, California. Because we test each product twice before it leaves our factory, rather than only testing a sample of each batch, we can guarantee most solid-state relays and optically isolated I/O modules for life. SNAP PAC Controllers SNAP PAC programmable automation controllers handle a wide range of digital, analog, and serial functions for data collection, remote monitoring, process control, and discrete and hybrid manufacturing. FREE PRODUCT SUPPORT For IIoT applications and easier integration with company systems, standalone and rack-mounted SNAP PACs include a built-in HTTP/ HTTPS server and RESTful API (application program interface). The REST API gives you secure, direct access to I/O and variable data using your choice of programming languages. No middleware, protocol converters, drivers, or gateways needed. Based on open Ethernet and Internet Protocol (IP) standards, SNAP PACs make it easier to build or extend a system without the expense and limitations of proprietary networks and protocols.
