Page 15: Chapter 2: Installation
2: Installation If you already know how you will use the SNAP PAC R-series controller and want to get it running quickly, follow the sections in this chapter. To learn about communication options and networking, start on page 13. Specifications are listed on page WHAT YOU WILL NEED You’ll need the following items to install a SNAP PAC R-series controller:... - Page 16 INSTALLING HARDWARE Modules snap into position in the row of connectors on the SNAP PAC rack. Each module connector has a number. NOTE: R-series controllers with serial numbers lower than 600,000, and all SNAP-PAC-R1-B controllers, are limited to eight 4-channel digital modules per rack, located in the first eight positions. Place the rack so that the module connector numbers are right-side up, with zero on the left.

Page 17: Removing A Module
CHAPTER 2: INSTALLATION Removing a Module If the modules are held in place with screws, remove them. Holding the SNAP module tool (provided) as shown in the illustration at right, insert it into the notch at the base of the module. Squeeze the module tool against the module to open the release latch, and pull straight up on the module to remove it. -

Page 31: Attaching The Controller To An Existing Ethernet Network
CHAPTER 3: SYSTEM INFORMATION NOTE: Make sure you put 3 and 6 on the same pair, or you may experience noise and distance limitations. Also, make sure to include all pairs, since they are required for 100 Mbps. Attaching the Controller to an Existing Ethernet Network The first rule in attaching SNAP PAC R-series controllers to an existing network is to work closely with your system administrator, who must determine network topology and hardware. -
Page 32: Using The Controller In An Independent Network
NETWORKING Using the Controller in an Independent Network The third way SNAP PAC R-series controllers can be used is by developing an independent network. An independent network gives a high level of communication speed and volume, as well as high security. If you have no existing Ethernet network, you can use off-the-shelf Ethernet components to build one. -
Page 33: Network Architecture Diagrams
CHAPTER 3: SYSTEM INFORMATION Network Architecture Diagrams Because SNAP PAC R-series controllers have two Ethernet interfaces and an RS-232 serial interface—and Wired+Wireless PACs add a wireless LAN interface—these controllers are suitable for use in a variety of system layouts and architectures. For example, the independent Ethernet interfaces let you configure a network for link redundancy or segmented networking. -
Page 34: Network Segmenting: Wired And Wireless Networks
NETWORKING Network Segmenting: Wired and Wireless Networks The network shown in this diagram requires a Wired+Wireless R-series controller (SNAP-PAC-R1-W or SNAP-PAC-R2-W). The PAC runs a PAC Control strategy and controls one or more remote I/O units via a wireless access point. The controller is also connected to a separate, wired enterprise network through one of its wired Ethernet network interfaces. -

CHAPTER 3: SYSTEM INFORMATION Dimensions for Wired+Wireless Models This diagram applies to Wired+Wireless R-series PACs (SNAP-PAC-R1-W and SNAP-PAC-R2-W). INFORMATION ON FEATURES All SNAP PAC R-series controllers offer many features, described in the following sections and summarized in the table on page Digital Point Features To configure digital point features, see the PAC Control User’s Guide. -
Page 42: Analog Point Features
INFORMATION ON FEATURES Watchdogs—You can set a watchdog to monitor communication with the PC or other host device. If the host does not write data to the controller for the length of time set in the watchdog, the controller automatically sets digital and analog I/O points to values you have chosen. This action makes sure the process is brought to a safe state if communication fails. -
Page 43: Serial Communication
CHAPTER 3: SYSTEM INFORMATION Offset and gain—The controller can calculate offset and gain for analog input points. If a -50 mV to +50 mV input receives signals that are slightly off (not exactly -50 mV at the lowest point, for example), the offset and gain can be calculated so that values will appear accurately when read. -
Page 44: Additional Features
INFORMATION ON FEATURES Each SNAP PAC R-series controller can run up to 96 PID loops. PID loops run on the I/O side, independently from a PAC Control strategy. To use PID loops, configure them in PAC Control or PAC Manager, and use PAC Control tuning tools for ease in debugging. -

Page 69: Troubleshooting I/O Modules: Frequently Asked Questions
A: Failure of SNAP digital I/O modules is very rare and normally caused by misapplication, miswiring, or using the module at the wrong logic voltage. As with Opto 22’s other digital I/O module families, there is no one way in which SNAP I/O modules fail. Output modules normally fail in a different way than inputs. -
Page 70: Snap Analog Troubleshooting
This causes the load to behave as a half-wave rectifier. Opto 22 output modules have a built-in R-C snubber circuit in parallel with the output. The capacitor in this circuit charges up but cannot discharge through the series diode, causing a voltage to appear across the output terminals. - Page 71 Opto 22 offers DIN-rail-mountable power supplies for use with SNAP I/O systems. Keep in mind that unless you purchase an isolated module, the channels on a SNAP input or output module are not isolated from one another.
