<strong>2704</strong> Controller St<strong>and</strong>ard IO<br />
17.6. STANDARD DIGITAL IO PARAMETERS<br />
This page allows access to parameters which set up the fixed digital IO connected to<br />
terminals D1 to D7 <strong>and</strong> DC.<br />
The st<strong>and</strong>ard digital IO1 to 7 can either be input or output as set up in configuration level, see<br />
Engineering h<strong>and</strong>book HA026933. The choices are:-<br />
1. Digital Input IO configured as a digital input<br />
2. On/Off IO configured as a digital output<br />
3. Time Proportion IO configured as a control output<br />
4. Valve Lower IO configured to raise the output of a motor valve <strong>controller</strong><br />
5. Valve Raise IO configured to lower the output of a motor valve <strong>controller</strong><br />
The parameters are accessed in the same way as the sections above. When the logic outputs<br />
are configured as time proportioning outputs, they can be scaled using the same procedure as<br />
the fixed relay output, described in 17.5.<br />
.<br />
The logic IO parameters are listed in the following table:-<br />

This page allows you to set up the Digital I/O<br />
Parameters. The parameters which appear<br />
depend upon the type of I/O configurated<br />
