Compatibility
Harmony rack I/O devices are fully compatible with existing INFI 90 OPEN systems. The controller can communicate with Harmony rack I/O and INFI 90 OPEN I/O simultaneously. Communication is over an I/O expander bus.
Rack I/O Components
As mentioned previously, the main components of Harmony rack I/O are I/O modules, termination units, and I/O expander bus (Fig. 1 and 2). The following sections provide further explanation.
I/O Expander Bus
The I/O expander bus is a high speed, synchronous, parallel bus. It provides a communication path between controllers and I/O modules. The I/O expander bus parallel signal lines are located on the MMU backplane. Inserting a rack-mounted controller and I/O modules into the mounting unit connects them to the expander bus.
I/O Module
An I/O module interfaces and processes field device input and output signals. There are several different I/O module types available. Table 1 lists the available module types and gives a brief description. All I/O modules share the same layout and connection, configuration, and mounting methods. Refer to the Harmony Rack Input/Output data sheets for individual I/O module
