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.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.

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