6. Installing the Controller CAUTION Make sure you are using a SNAP PAC rack for your SNAP PAC R series controller Legacy SNAP M series racks can also be used Using the wrong rack will severely damage the controller 1 2 Remove the controller from its packaging Turn off power to the rack assembly Align the controller connector with the mating connector on the mounting rack Seat the controller onto the connector and use the hold down screw to secure the controller in position Do not overtighten Using Category 5 or superior solid unshielded twisted pair cable connect the controller in one of the following ways Recommended for initial configuration Connect to a PC directly using an Ethernet crossover cable NOTE Wired wireless models must be configured using a wired network before they can be used on a wireless network NOTE If you use a crossover cable make sure to assign a fixed IP address to the network card NIC on your computer Otherwise if your network card is configured to get its IP address via DHCP when you unplug the computer from the network the computer will no longer have an IP address When you are finished using the crossover cable you can change the setting back to DHCP Connectto a standard 10BASE T or 100BASE TX Ethernet network that has a PC on the same subnet as the controller and does NOT have a Dynamic Host Configuration Protocol DHCP server NOTE When connecting the contoller to

DC input modules contain a full wave rectifier as opposed to the G1 and G4 modules which contain a bridge rectifier allowing hookup without regard to polarity Unlike output modules an input module s LED normally will not function as expected when the module has failed Failures on the field side of all types of Opto 22 digital O modules occur extremely rarely and are typically the result of misapplication The logic side failures of Opto 22 s I O modules are also extremely rare Usually a failure of the logic side is attributable to using the module at the wrong logic voltage or to miswiring Q I have an input module that seems to flicker when a voltage is applied to it What is happening here A Opto 22 s basic input modules contain full wave rectifiers In an AC application it is possible to destroy one half of the rectifier and still have the module function after a fashion The full wave rectifier turns into a half wave rectifier causing the module to turn on and off at the line frequency when an input is applied This may be seen visibly as flicker on the channel status LED 64 SNAP PAC R Series Controller User s Guide CHAPTER 4 MAINTENANCE AND TROUBLESHOOTING Digital logic devices having much faster detection times than the human eye can have serious problems with this failure mode For example a digital counter attached to a failed module will count at the input frequency This failure occurs most commonly
