Remote I/O Scanner Installation Be sure the rack is powered-down. Grasp the module firmly and insert it into the card guide. Align the module s printed circuit board with the connector on the rack backplane. Slide it towards the connector until it begins to seat. Place one thumb on the left of the top plastic flange and the other thumb on the left of the bottom plastic flange. Push the board into the connector until the top and bottom latches click onto the rack rails. Be sure the module has seated properly. If the rack is in a high-vibration area, use screws to secure the module in the rack. Remote I/O Scanner Removal Be sure the rack is powered-down. Grasp the module firmly at the top and bottom of the board cover with your thumbs on the front of the cover and your fingers on the plastic clips on the back of the cover. Squeeze the rack clips on the back of the cover with your fingers to disengage the clip from the rack rail and pull the board firmly to remove it from the backplane connector. Slide the printed circuit board along the card guide and remove it from the rack. IC66* Bus Connections For single (non-redundant) bus installations, the IC66* bus cable is connected to the upper four terminals of the Remote I/O Scanner (1 - 4 in the diagram). The lower eight terminals are not connected. CONNECT BUS STUB CABLE HERE TERMINALS FOR BUS A TERMINALS FOR BUS B NOT USED CONNECT BUS TO TOP FOUR TERMINALS SHIELD OUT For dual (redundant) bus installations, the serial bus cable from the Bus Controller on bus A connects to the center four terminals on the terminal strip (5 - 8 in the diagram). The cable from the Bus Controller on Bus B connects to the lower four terminals (9 - 12). The Remote I/O Scanner contains an integral bus switching relay; there is no need to attach an external Bus Switching Module for dual bus configurations. If there is a bus stub from the Remote I/O Scanner to additional devices which are controlled by its bus switching action, it connects to the top four terminals (1 - 4); otherwise the top four terminals are unused. The maximum exposed length of bare wires should be two inches. For added protection, each shield drain wire should be insulated with spaghetti tubing to prevent the Shield In and Shield Out wires from touching each other or the signal wires. On a bus, connect Serial 1 to the Serial 1 terminals of the previous device and the next device. Connect Serial 2 to the Serial 2 terminals of the previous device and the next device. Connect the Remote I/O Scanner s Shield In terminal to Shield Out of the preceding device. Connect Shield Out to Shield In of the next device. If the Remote I/O Scanner is the first de5 Remote I/O Scanner GFK-0539C Bus Expansion Modules August 1997 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 65-5 vice on a bus, Shield In can be left unconnected. If it is the last device on a bus, Shield Out can be left unconnected. Note that the IC66* bus connections for a Remote I/O Scanner are not the same as the connections for an IC697 bus controller, even though the terminals are physically identical. SHIELD OUT a44755 SER1 SER1 SER2 SER2 SHIELD IN IC66* BUS CONTROLLER SHIELD OUT SHIELD IN REMOTE I/O SCANNER IC66* Bus Termination If the Remote I/O Scanner is at either end of a bus (electrically), connect the appropriate terminating resistor across the Serial 1 and Serial 2 terminals. Impedance for the IC66* bus will be 75, 100, 120, or 150 ohms. Chapter 2 of the I/O System User s Manual (for IC660*) lists the correct impedance to use for each approved type of bus cable. In a redundant bus application, if either cable of the dual bus ends at the Remote I/O Scanner, it must have its own terminating resistor. The upper four connectors are never terminated in a dual bus configuration. Note If the Remote I/O Scanner will be powered up when not connected to a properly-terminated bus, connect a 75-ohm resistor across its Serial 1 and Serial 2 terminals to assure proper powerup. Serial Port Connections The Remote I/O Scanner s serial port can be used for connection to a multidrop communications network or for direct connection of a programmer running the serial version of IC641 Programing Software. Serial Port Termination If the Remote I/O Scanner will be at the end of a communications network, or if a programmer will be connected directly to it, the serial port must be terminated by connecting a 220 ohm resistor across pins 10 and 11 and another 220 ohm resistor across pins 8 and 15. These connections must be made inside the connector s D-shell. At the other end of the cable, terminate the SD and RTD pins in the same way. Direct Programmer Connections If the programmer is equipped with the parallel version of MS-DOS programming software and a Workstation Interface board, connection is made to a Bus Transmitter module in rack 0. If the programmer is equipped with the serial version of MS-DOS programming software and a Workstation Interface board, connection is made to the serial port on the Remote I/O Scanner module. If the programmer does not have a Workstation Interface board, connection must be made via an intermediate RS422/RS485 to RS232 converter. If the serial port is needed for connection to a multidrop communications network, an intermediate connector can be used. See the Remote I/O Scanner User s Manual for details. Programmer Grounding For proper operation, the programmer must have a ground connection in common with remote drop rack 0. Normally, the common ground connection is provided by connecting the programmer s power cord to the same power source (with the same ground reference point) as the rack. If a common ground cannot be established, use the RS-422 Isolated Repeater/ RS-232 Converter IC655CCM590, or an equivalent product to protect the equipment. Configuration A Remote I/O Scanner must be configured to: Assign its Device Number (serial bus address). Assign its baud rate. Specify starting references and lengths for discrete inputs and outputs, and for analog inputs and outputs. Specify the Remote Drop ID. GFK-0539C Remote I/O Scanner 6 Bus Expansion Modules August 1997 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 65-6 Configuration can be done with: MS-DOS programming software release 3.0 or later. This software provides full configuration of I/O modules and allows selection of module options. An IC66* Hand-held Monitor, version 4.0 or later. The HHM automatically assigns I/O references to the modules in the remote drop. The I/O modules in the remote drop operate in default mode if a Hand-held Monitor is used to enter or change configuration. If the remote drop includes any analog expanders, a Hand-held Monitor cannot be used for configuration. IC697 PLC Configuration If the system host is an IC697 PLC, each Remote I/O Scanner must be added to the PLC configuration. With MS-DOS programming software release 3.0 or later, a separate program folder should be created for each remote drop. The folders should be organized so that the remote drop folders are located in the central PLC folder. The Remote I/O Scanner User s Manual gives complete configuration instructions.

I/O Link Interface Module IC697BEM721 Bus Expansion Modules GFK-0645C August 1997 1 66 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 66-1 I/O Link Interface Module (IC697BEM721) datasheet GFK-0645C Module Features IC697 PLC interface to CNC-compatible serial I/O link. I/O Link master or slave. Occupies single slot in PLC rack. Three status LEDs I/O Link reset pushbutton. 1.5 MHz serial port transmission rate. Overview The Fanuc I/O Link is a serial interface that provides high-speed exchange of I/O data between a master device and up to 16 slaves. The maximum distance between individual devices on an I/O Link is 10 meters (33 feet). If greater distances are required between modules, optional fiber optics cable and Optical Adapters can be used to increase the maximum distance between individual devices to 100 meters (330 feet). Up to four I/O Link Interface Modules can be installed in an IC697 PLC. Each I/O Link Interface Module can be used in either master or slave mode. Usually, when there are multiple I/O Link Interface Modules in the same PLC, they are on separate I/O Links. However, it is possible to have more than one I/O Link Interface Module in the IC697 PLC connected to the same link, if that suits the needs of the application. When used as a master, an I/O Link Interface Module can exchange up to 1024 discrete inputs and 1024 discrete outputs with slave devices. Potential slaves include the IC693 PLC, Series 0 CNC, and Power Mate CNC. When used as a slave, the IC697 I/O Link Interface Module can exchange up to 64 discrete inputs and 64 discrete outputs with the master. The master may be another IC697 PLC, a Series 15, Series 16, or Series 18 CNC, a Series 0 Model C CNC, or an F-D Mate CNC. The IC697 PLC and Series 0 CNC can be used as either master or slave. a45005 MODULE OK LINK ACTIVE LINK CFG I/O LINK The I/O Link Module is configured using the MS-DOS programming software. Application software, supplied on diskettes with the I/O Link Module, can be used to set up and control the I/O Link. This application software can also be used to assign the location of the input and output data to and from the I/O Link, and to provide diagnostics capabilities for the I/O Link. The MS-DOS programmer is used to integrate this application software with the rest of an application program. MS-DOS is a registered trademark of Microsoft Corporation. GFK-0645C I/O Link Interface Module 2 Bus Expansion Modules August 1997 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 66-2 Module Description The I/O Link Interface Module occupies one slot in the IC697 PLC rack.

Module OK: indicates the module s operating status. Link Active: indicates the module s communications status. Link Cfg: indicates whether I/O Link configuration has occurred. Reset Pushbutton The Reset pushbutton provides a convenient means of reset if a failure occurs. If the module is being used as a master, pushing the Reset button resets both the module and operation of the link. The application program must be used to re-initialize the link. If the module is being used as a slave, pushing the Reset button resets the module, if a fault has caused the module to stop operating while the rest of the link continues to function. Serial Ports The front of the I/O Link Interface Module has two 20-pin, D connector, RS-422/485 serial ports. These ports are used for connection to the Fanuc I/O Link. Application Software The IC697 I/O Link Interface Module is provided with an application software diskette. Program logic on the diskette can be used to integrate up to four I/O Link Interface Modules into the PLCs application program. It will transfer I/O data between the module and the PLC, perform diagnostics functions, and transfer application program commands to the module. Additional application program logic can be created to perform the following functions: 1. To specify the number of I/O Link Interface Modules present in the PLC. 2. To specify, for each I/O Link Interface Module: A. A rack and slot location. B. Master or slave operation. 3. And, for each I/O Link Interface Module that will be a master: A. To assign a data length and I/O addresses for each slave on its link. B. To control operation of the link and monitor module and link status. The I/
