Basic HIO OperationsThe HIO unit has Prizm (Operator interface) as well as programmable logic features. The user can implement logic, specific to application using standard Ladder programming. The HIO unit has four 32-bit High Speed Counters(Normal and Quadrature Mode), Rate measurement capability (max. up to 25kHz), Timers and Counters, Internal Coils, retentive and non-retentive memory and PID functionality. A PLC logic task can be programmed for continuous scanning, or only when a specific screen is showing. The user can also include a Programmable logic task in power on as well as Global task. The HIO operator interface functions revolve around Screens and Tasks that can be assigned to keys, screens and application. The HIO can also display an Alarm conditions.
Supported Tasks are listed below: 

Digital I/O
The HIO Keypad series can have up to 16 digital inputs and 12 digital outputs on the unit. Digital inputs are high impedance 24 V DC and outputs are either relay (NO), open collector or a combination of both. The Digital I/O capability of HIO units can be expanded using external add on I/O Modules.
Analog I/O
The HIO controllers can have up to 4 analog inputs and 2 analog outputs. Analog inputs are mA, mV and RTD. Analog outputs are 4-20 mA. The Analog I/O capability of HIO units can be expanded using external add on I/O Modules.
PID 
The built-in PID controller can process 12 independent inputs in addition to the Analog inputs of the unit. The input to the PID Controller is a data register, which can hold an analog input or any other value.

Keys Task
Keys in HIO can be assigned Tasks for three instances: when the key is pressed , while the key is pressed and when the key is released. Multiple tasks can be assigned to a key. Also different screens can have different key definitions. In addition to above-mentioned tasks, Key’s specific tasks can be defined for keys. These include tasks for data entry, alarm management etc. These definitions allow complete flexibility in cursor control and key operations when changing data.
Screens
Up to 65535 screens can be defined in HIO. Screen Tasks can be assigned before showing a screen, while showing a screen and after hiding a screen. Various types of objects such as plain text objects, Data display (coil status, register value, register dependent text), Data entry objects and Alarm objects can be defined on screen. Two screens can be associated to avoid duplication of screens and objects.
Data entry objects can have limits and math associated. Various types of data formats are available which help the user to edit data easily. Floating Point data entry is supported.
Alarms
Alarms can be defined in HIO. Alarms can either be consecutive or discrete. User-friendly alarm object can be defined on the display. Alarms can be real time or historical. Keys can be assigned to acknowledge alarm, view and scroll.
Dual Port Support
HIO units (except HIO010) have two communication ports. Both ports can be configured as RS232, CMOS, RS485 / RS422 programming port or to connect a Printer / PLC / SCADA / Drive etc. Drivers can be downloaded in HIO units for Dual Port application
Configuration Software
Prizm Setup Software is a compact, Windows® based software to configure the HIO Series Interfaces. Prizm configuration tools and easy approach can help you create your applications quickly and easily. By using Prizm Setup Software features, you can be more effective in presenting your application. Whether you need a small application to monitor data or a bigger application for both monitoring and control, Prizm Setup Software has it all.
