IC693BEM321 I/O LINK Master Module
The Series 90-30 I/O LINK Master Module (IC693BEM321) allows a Series 90-30 PLC to act as a
master on a proprietary I/O LINK. The I/O LINK is a serial interface which provides
high-speed exchange of I/O data between the master and up to 16 slaves. The master can receive
1024 discrete inputs from slaves, and send up to 1024 discrete outputs.

Figure 8-16. Example of I/O LINK Master System Configuration
The illustration above shows a simple I/O LINK system: a Series 90-30 PLC used as a master, a
Series 90-30 Hand-held Programmer, an I/O LINK, and one slave. In the illustration, the slave is a
Power Mate CNC. Other devices that can be used as slaves include the Series 90-70 PLC, the
Series 90-30 PLC, the Series 0 CNC, Connection Units, and Operator Panels.
The module can be configured using a Series 90-30 Hand-held Programmer (HHP) or the
