[Tweet](https://twitter.com/share) ### Move up to SNAP PAC—and keep racks and field wiring intact [![SNAP-PAC-R1-B](https://blog.opto22.com/hs-fs/hubfs/OptoNews/snap-pac-r1-b_164x224.png?t=1467736113312&width=164&name=snap-pac-r1-b_164x224.png "SNAP-PAC-R1-B")](http://www.opto22.com/site/pr_details.aspx?cid=4&item=SNAP-PAC-R1-B)Have you seen some of our newer high-density, high-speed, or multifunction [I/O modules](http://www.opto22.com/site/pr_selector.aspx?cid=1&qs=1003) and wished you could use them in your legacy SNAP Ultimate or SNAP Ethernet I/O system?  Have you wanted to build an easy-to-use [*groov* mobile interface](http://groov.com/?__hstc=256016212.9ad34b9358316c229587be2701c27335.1458061256007.1467737390693.1467762210924.343&__hssc=256016212.7.1467762210924&__hsfp=3646994070) for your legacy system? Or wanted to log a lot more data locally?  If so, be sure to check out the [SNAP-PAC-R1-B programmable automation controller](http://www.opto22.com/site/pr_details.aspx?cid=1&item=SNAP-PAC-R1-B).  Like our other R-series rack-mounted controllers, the R1-B works with our most up-to-date control and HMI software—[PAC Project](http://www.opto22.com/site/pr_details.aspx?cid=1&item=PACPROJECTBAS)—and handles all the latest SNAP I/O modules: [analog](http://www.opto22.com/site/pr_selector.aspx?cid=1&qs=100310031044), [digital](http://www.opto22.com/site/pr_selector.aspx?cid=1&qs=100310071044), and [serial](http://www.opto22.com/site/pr_selector.aspx?cid=1&qs=100310181044).  But it also snaps into a **B-series rack** (the one with the blue connector), just like your SNAP Ultimate and SNAP Ethernet brains. So you can move up to the latest automation hardware and software and **keep the same mounting racks and field wiring** you already have. - Use the R1-B as a controller or simply as the brain for an I/O unit. - Get local, removable data storage through a microSD slot that takes microSDHC cards up to 32 GB. - Set up link redundancy using the controller's two independent Ethernet network interfaces.  - Move up to an integrated FPU (floating-point unit) and substantially larger battery-backed RAM. - Communicate simultaneously with a variety of systems and equipment using several built-in protocols, including TCP/IP, EtherNet/IP for Allen-Bradley® PLCs, PPP, Modbus®/TCP, SNMP for network management, and SMTP for emailing. - Access data easily with a RESTful API and HTTP/HTTPS server, available with firmware R9.5a or higher (coming soon!). - Use our free integration kits to communicate via serial Modbus, DNP3, and Controller Area Network (CAN). For detailed information about migrating to the SNAP PAC System—options, advantages, and gotchas—see the [SNAP PAC System Migration Technical Note](http://www.opto22.com/site/documents/doc_drilldown.aspx?aid=3149).  [See specs for the SNAP-PAC-R1-B](http://www.opto22.com/site/pr_details.aspx?cid=1&item=SNAP-PAC-R1-B).
