The SNAP-PAC-R2 programmable automation controller provides control, communication, and I/O processing in a compact, rack-mounted package. One of four components of the SNAP PAC System, the SNAP-PAC-R2 is fully integrated with PAC Project software, SNAP PAC brains, and SNAP I/O modules.
Used with the included PAC Project Basic software suite (or PAC Project Professional, purchased separately), the Ethernet-based SNAP-PAC-R2 can handle almost all your industrial control, remote monitoring, and data acquisition needs.
System Architecture
This intelligent, flexible PAC can be used in several ways. The SNAP-PAC-R2 can provide complete cell control on its own rack with I/O modules. It can also control SNAP PAC and groov EPIC I/O units at the same time for a larger system. 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 even be used as intelligent remote I/O for Allen-Bradley Logix PLC systems, such as ControlLogix and MicroLogix.
Networking
Two independent, 10/100 Mbps Ethernet network interfaces are included on each SNAP-PAC-R2. 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. 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.
