The Series 90–70 I/O Link Interface Module (IC697BEM721) is used to interface a Series 90–70 PLC to GE Fanuc and Fanuc products which may also be placed on the proprietary Fanuc I/O Link. 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.

Up to four I/O Link Interface Modules can be installed in a Series 90–70 PLC. They can be located in the CPU rack and in expansion racks. Each I/O Link Interface Module can be used in either master or slave mode.

GFK-0644A

Two I/O Link Interface Modules are shown in the example system illustrated above––one in the CPU rack and the other in an expansion rack. Each module is set up as a master with its own I/O Link. In this example, both of the I/O Link Interface Modules exchange data with P ower Mate CNCs. Usually, when there are multiple I/O Link Modules in the same PLC, they are on separate I/O Links as shown here. However, it is possible to have more than one I/O Link Interface Module in the Series 90–70 connected to the same link, if that suits the needs of the application.

Master or Slave Operation

When used as a master, an I/O Link Interface Module can receive up to 1024 discrete inputs from devices on the I/O Link, and send up to 1024 discrete outputs. P otential slave devices include the Series 90–30 PLC and the Power Mate CNC.

When used as a slave, the Series 90–70 I/O Link Interface Module can receive up to 64 discrete inputs from the master, and send up to 64 discrete outputs. The master may be another Series 90–70 PLC, a Series 15, Series 16, or Series 18 CNC, a Series 0 Model C CNC, or an F–D Mate CNC. The Series 90–70 PLC and Series 0 CNC can be used as either master or slave.

In the example system shown below, the Series 90–70 PLC shown at the top functions as an area controller for three machine cells. The area controller has two I/O Link Interface Modules, each of which operates as an I/O Link master.

In this system, the left I/O Link from the area controller goes to cell 1, where a Series 0 CNC, two single–axis Power Mate CNCs, and a Series 90–30 PLC are the slaves. They control the operations of a large machine and its auxiliary equipment. The right I/O Link from the area controller goes to another Series 90–70 PLC. That PLC serves as a slave on the link to the area controller, and as a master on two other links to smaller machine cells. In cell 2, a Series 0 CNC and a Series 90–30 PLC are the slaves. In machine cell 3, the slaves are a Series 90–30 PLC and two Power Mate CNCs.

Application Software

The Series 90–70 I/O Link Interface Module is provided with two application software diskettes (catalog number IC641SWP708), a 3-inch and a 5-inch diskette. The content of these diskettes is the same.

This application software can be used to integrate up to four I/O Link Interface Modules into the PLC’s application program. There are three Program Blocks on a diskette. Each will transfer I/O data between the module and the PLC, perform diagnostics functions, and transfer application program commands to the module.

One Program Block is selected as being most appropriate for the application, and added to the application program. 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 in the Series 90–70 PLC. B. Master or slave operation.

3. And, for each I/O Link Interface Module that will be a master: A. T o 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.

Chapter 4 explains how to select the best Program Block for your system, and how to incorporate it in an application program.

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 and a fault has caused the module to stop operating, pushing the Reset button resets the module while the rest of the link continues to function.

Note

The Reset pushbutton should not be used if the link is operating normally. Pressing Reset during normal operation causes the link to stop operating. The diagnostic program logic interprets this as an external link failure.

Serial Ports

The front of the module has two 20–pin, D connector, RS–422/485 serial ports. These ports are used for connection to the I/O Link.

8 Series 90t-70 I/O Link Interface Module User’s Manual – February 1993

GFK-0644A

Operation of the I/O Link

The I/O Link consists of a full duplex communications channel. Physically , the link consists of two twisted pairs of wire and a signal ground conductor. These wires are contained in a cable that has an over–all shield. Signals are of the differential type and a wire pair is used for each signal. Signal levels are compatible with specification EIA RS–422/RS–485. The signal baud rate is 1.5 Mbaud maximum.

Input and Output Data

The master on an I/O Link can send 1024 outputs and receive up to 1024 inputs from slave devices. A slave can send and receive either 32 or 64 inputs and outputs. For each link device, inputs and outputs have the same meaning:

Input Data is data received from the link.

Output Data is data sent to the link.

So the same set of data is considered output data by the device that sends it and input data by the device that receives it.

OUTPUTS

For each Series 90–70 I/O Link Interface Module used as a master, %I and %Q references and data lengths for each slave are assigned within the application Program Block, using Logicmaster 90. Instructions for doing this are given in chapter 4. For other types of devices on the link, references and data lengths are assigned differently. For details on how a specific type of device handles its I/O Link data, you should refer to the User’s Manual for that device.
