SNAP PAC S-series Programmable Automation Controller for Ethernet Networks - REST API

Now developer and IoT ready with a built-in HTTP/HTTPS server and RESTful API. See Programming, below.

** Compatible with groov EPIC. You can control groov EPIC I/O units with a SNAP PAC S-series controller running PAC Control R10.a or higher. **

The SNAP-PAC-S1 programmable automation 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 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-S1 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. SNAP PAC S-series controllers are also compatible with Opto 22's groov products and groov View HMI tool.

Networking
The controller is compact and industrially hardened. It includes two independent Ethernet network interfaces with separate IP addresses, which can be used to segment the control network from the company network or for redundant Ethernet links. 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 or higher.

The SNAP-PAC-S1 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. (Note: If you are using the S1 with mistic I/O units, use the legacy versions of the PAC Control, PAC Display, and PAC Manager guides.)

If you need Factory Mutual approval, see the SNAP-PAC-S1-FM.
If you need additional serial ports, see the SNAP-PAC-S2.
To compare controller features, see the SNAP PAC Controller and Brain Comparison Chart.
