Note that minimum firmware R9.5a and PAC Project R9.5a are required to use the REST API. In addition, two Node-RED nodes are available. For complete API documentation and steps for getting started, see. 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. 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).

You create and debug the strategy on your computer and then download it to the R1, where it runs independently. PAC Control is a flowchart-based tool for developing control applications, or strategies. The SNAP-PAC-R1 is programmed using the included PAC Control software. 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. 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. Two independent, 10/100 Mbps Ethernet network interfaces are included on each SNAP-PAC-R1. It can even be used as intelligent remote I/O for Allen-Bradley Logix PLC systems, such as ControlLogix and MicroLogix.
Or the R1 can be used in a more extensive distributed control system as an I/O unit controlled by a groov EPIC processor or a SNAP PAC S-series controller. It can also control SNAP PAC and groov EPIC I/O units at the same time for a larger system.
The SNAP-PAC-R1 can provide complete cell control on its own rack with I/O modules. This intelligent, flexible PAC can be used in several ways.

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. 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. The SNAP-PAC-R1 programmable automation controller provides control, communication, and I/O processing in a compact, rack-mounted package.
You can control SNAP PAC R-series I/O units with groov EPIC or control groov EPIC I/O units with a SNAP PAC R-series controller running PAC Control R10.a or higher. Now developer and IoT ready with a built-in HTTP/HTTPS server and RESTful API. Build your system with the SNAP I/O Configurator.
