IO Devices

Tascus stations can connect to physical inputs and outputs through an IO device, giving operators hardware controls and visual status indicators at the workstation. Push buttons let operators run a sequence without touching the screen — continue, abort, or step back — while a light stack shows production status across the station at a glance.

Both run through the same IO device and are set up in the same place: Settings > System IO. This article covers enabling inputs and outputs, the default push-button configuration, light stack setup, and the supported hardware.

What you'll need

A Tascus IO device at the station. There are two standard options:

Both connect to Tascus the same way and are configured using the steps below.

Station Push Buttons

Station push buttons replace some of the touchscreen interaction when running Tascus sequences, so operators can drive a sequence with physical buttons at the workstation.

The following table lists the configuration of the push buttons:

DI Function

Function

Sequence Continue

Start sequence / Complete step / Next / Pass

Sequence Abort

Abort sequence / Cancel / Fail

Sequence Back

Back one step (when running a sequence)

Step Functions

Used is certain step types

To enable this functionality, all you need to do is check Inputs Enabled, then select which input is used for which button.

Light Stack

A 4-way light stack can be added to a Tascus station IO device, it will light up with the following status:

State

Light Status

Non Production

All Off

Production Running

Green

Production Slow (behind standard time)

Amber

Planned Downtime

Amber

Unplanned Downtime

Red

Configure this under Settings > System IO

Enable Outputs, then configure output channels to lights.
