SNAP PAC S-series Wired + Wireless Automation Controller

Ref: SNAP-PAC-S1-W

The SNAP-PAC-S1-W programmable automation controller (PAC) provides all of the same features as the SNAP-PAC-S1 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-S1-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.

Networking
The SNAP-PAC-S1-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.

The SNAP-PAC-S1-W also has three serial ports: an RS-232 port with full hardware handshaking, ideal for PPP communication using a modem; another RS-232 port for connecting directly to serial devices; and an RS-485 port for connecting to SNAP PAC Serial brains or to legacy mistic I/O units.

Programming and Protocols
The SNAP-PAC-S1-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. The controller has 128 MB of RAM and can run up to 32 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-S1-W provides communication. Because it is based on the Internet Protocol (IP), the SNAP-PAC-S1-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.

If you need additional serial ports, see the SNAP-PAC-S2-W.

If you do not need a wireless LAN interface, see the SNAP-PAC-S1.

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.

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.

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.

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.
