SNAP-PAC-S2-W

Production Specification

*** NOTE: This part is obsolete and no longer available. ***

-----------

The SNAP-PAC-S2-W programmable automation controller (PAC) provides all of the same features as the SNAP-PAC-S2 and adds a wireless LAN interface as well.

Compact and industrially hardened, this controller provides powerful, real-time control and communications to meet your industrial control, monitoring, and data acquisition needs. One of the four components of the SNAP PAC System, the SNAP-PAC-S2-W is fully integrated with PAC Project software, SNAP PAC brains, and SNAP I/O modules to form a complete control system. The SNAP PAC System includes digital and analog control, serial string handling, PID loops, and enterprise connectivity.

Programming
The SNAP-PAC-S2-W 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 PAC, where it runs independently.

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 at groov.

Networking
The SNAP-PAC-S2-W includes a wireless LAN interface that supports 802.11a, b, and g network standards. The controller can be used in infrastructure or ad-hoc mode. For security, 802.11i standards are supported, including WPA2-AES as well as WPA and WEP for backwards compatibility.

In addition, the PAC includes two independent, 10/100 Mbps wired Ethernet network interfaces. You can use the PAC wirelessly, on a wired network, or both at once. All three interfaces—one wireless and two wired—have separate IP addresses. They 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. You can also set up a system with redundant controllers using two identical S-series controllers,  the SNAP PAC Redundancy Option Kit, and PAC Project Professional 9.0.

The SNAP-PAC-S2-W controller is well suited for use with serial-based I/O units and serial devices. The SNAP-PAC-S2-W has four serial ports that can be individually configured as either RS-232 or RS-485 (2-wire or 4-wire). Configured as RS-232, serial ports support serial device communication or a Point-to-Point Protocol (PPP) modem connection for creating a TCP/IP network over PSTN (Public Switched Telephone Network) lines. Configured as RS-485, serial ports connect to SNAP PAC Serial brains or to legacy Opto 22 mistic™ I/O units, including the serial B3000 brain and remote mistic bricks. (Note: If you are using the S2 with misticI/O units, use the legacy versions of the PAC Control, PAC Display, and PAC Manager guides.)

Protocols
In addition to control, the SNAP-PAC-S2-W provides communication. Because it is based on the Internet Protocol (IP), the SNAP-PAC-S2-W 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.
The SNAP-PAC-S2-W can be panel or DIN-rail mounted. For DIN rail, see the SNAP-S2DIN DIN-rail mounting kit.

If you need fewer serial ports, see the SNAP-PAC-S1-W.

If you do not need a wireless LAN interface, see the SNAP-PAC-S2.

For more details, see the Specifications tab and the Data Sheet.

SNAP PAC REST API and the Internet of Things - for OT Professionals

We’ve all heard about the Internet of Things (IoT) and its promises: bringing useful data directly to people who make business decisions, and enabling machines to communicate with each other and make decisions for human benefit.

But how does the IoT actually work? How does the data get from inside these physical "things" to computer networks where it can be used?

This technical paper describes that pathway for OT (operational technology) professionals—automation professionals. It describes the kinds of data you may be asked to provide and why. It explains how data from physical "things"—especially existing sensors and actuators that have no IoT capabilities built in—can be securely communicated to company computer networks, without disturbing control networks.

The paper also explains concepts important to any IoT strategy, like encryption and authentication, and introduces a new method to achieve the IoT results you need now, without requiring a complex chain of conversion hardware and software.

Case Study: Natural Gas Fueling Stations Communications

In recent years, environmental benefits, improvements in automotive engine design, and the lower production cost of natural gas (compared to heavy diesel fuel) have made use of natural gas vehicles (NGVs) more attractive and cost feasible—particularly for public transportation. One of the other advantages of NGVs is that they can be refueled simply by tapping into existing natural gas lines. The Madrid city government has invested $47 million dollars in a custom refueling station and parking depot for 300 natural gas powered buses in the Sanchinarro area of Madrid. An Ethernet-based industrial automation, data acquisition, and communications system—based on Opto 22’s SNAP PAC platform and implemented by Spanish integrator Optomation Systems—serves as the communications backbone that keeps the Sanchinarro station operating efficiently. The system employs a number of industrial and IT protocols, including FTP, SNMP, OPC, Modbus/TCP, and M-Bus to communicate more than 600 different data values to and from the Sanchinarro station’s equipment, systems, and external databases.

Firmware for all SNAP PAC products

Firmware for all SNAP PAC products (single download)

See the README document for information on changes and fixes in the current version of this product's firmware.


Effective April 2, 2018, some SNAP PAC controllers and brains have new flash components. These units ship with firmware R9.5g (or higher) and new bootloader firmware.

PAC firmware versions R9.5f and lower are not compatible with the new component. If you inadvertently install firmware R9.5f or lower on one of these units, you can recover by using the Failsafe Bootloader Mode to install firmware R9.5g or higher.

For more information about the new flash component, see KB87213.

For details on Failsafe Bootloader Mode, see "Replacing Damaged Firmware" in the PAC Manager User's Guide (form 1704). NOTE: Opto 22 recommends that you always use the most recent release of PAC Manager.

This download is freeware. Before downloading, read the Legal Agreement.

OptoTagPreserve

OptoTagPreserve copies variables from your PAC Control strategy running on a SNAP PAC controller and saves them in a password-protected binary file or a plain-text XML, OptoScript, or init.txt file.

The primary reason you would use this utility is to make it easier to preserve variable states when you need to update firmware on the controller. Updating firmware erases battery-backed data including persistent variables and variables initialized on strategy download. Use OptoTagPreserve before loading new firmware to archive tag values to the computer, and then restore them after firmware is loaded and the strategy has been downloaded.

IMPORTANT:

  • Make sure the strategy is stopped before restoring tag values. If the strategy is running, unexpectedly changing values can cause unpredictable results with strategy operation.
  • Writing to a plain-text file requires that the strategy contain a special variable allowing plain text.

See the technical note included in the download for complete information on using the utility.
