IC693BEM320 I/O LINK Interface (Slave) Module
The I/O LINK Interface module (IC693BEM320) provides an interface between a Series 90-30
PLC and a proprietary I/O LINK in a CNC (Computer Numerical Control), or a
Series 90-70 PLC. This module is configured as a slave device only (see the IC693BEM321 for
master applications). The I/O LINK is a serial interface which provides high speed
exchange of data between a master and up to 16 slaves. An example of a Series 90-30 PLC in a
I/O LINK system configuration is shown in the following illustration.

Figure 8-15. Example of a Series 90-30 PLC in a I/O LINK Configuration
The Series 90-30 I/O LINK Interface module is configured as a slave device only and allows the
Series 90-30 PLC to send either 32 or 64 I/O points to the I/O LINK. The I/O LINK module must
be configured as either a 32 or 64 point I/O module during installation by setting a jumper plug
inside of the front cover of the module to either 32 I/O or 64 I/O.
An I/O LINK Interface module can be installed in any model of Series 90-30 PLC, and any
number of I/O LINK Interface modules can be installed in a system within the current limits of the
baseplate and other I/O modules installed in the baseplate. For more details, see "Load
Requirements for Hardware Components" in Chapter 12 of this manual.
