Avatar Definition

TeSys avatars bring ready-to-use functions through their predefined logic and associated physical devices. The avatar logic is executed in the bus coupler. The bus coupler manages data exchanges internally within the TeSys island , and also externally with the PLC.

There are four types of TeSys avatars :

System avatar

Represents the whole island as a system. The System avatar allows setting the network configuration and computes TeSys island level data.

Device avatars

Represent functions performed by switches and I/O modules.

Load avatars

Represent functions related to specific loads, such as a forward-reverse motor. Load avatars include the appropriate modules and operating characteristics to serve the load type. For example, a Motor Two Directions avatar includes two starter modules, accessories, pre-programmed control logic, and a pre-configuration of the available protection functions.

Standard (non-SIL*) Load avatars provide the following:

Local control

NOTE: Local control is applicable for all Load avatars (except PIM avatar ).
Local trip reset (to allow an operator to use a local input to trigger the local trip reset on rising edge of the input. When the input changes from 0 to 1, then the trip reset of avatar is executed)

NOTE: Local trip reset is applicable for all Load avatars (except PIM avatar ).
Bypass (to allow an operator to use a local command to temporarily bypass a trip condition and continue the operation of the avatar )
Process variable monitoring

Application avatars

Represent functions related to specific user applications, such as a pump or conveyor. Application avatars provide the following:

Local control
Local trip reset (to allow an operator to use a local input to trigger the local trip reset on rising edge of the input. When the input changes from 0 to 1, then the trip reset of avatar is executed)
Bypass (to allow an operator to use a local command to temporarily bypass a trip condition and continue the operation of the avatar )
Manual mode override (to allow an operator to use a local input to override the configured control mode and control the avatar from a local command source)
Process variable monitoring

For example, a Pump avatar includes the following:

One starter module
One or more digital I/O modules for local control, local trip, and process variable (PV) switches
Configurable control logic
Pre-configuration of the load and electrical functions

PV inputs receive analog values from sensors such as a pressure meter, a flow meter, or a vibration meter. PV switches receive discrete signals from switches such as a flow switch or a pressure switch.

Operational control (Run and Stop command) of the avatar in autonomous mode is configurable for up to two PV inputs or PV switches. It includes settings for the threshold and hysteresis for analog inputs, and positive or negative logic for both analog and digital inputs for the Pump avatar.

The avatars installed on the TeSys island are controlled by the TeSys island bus coupler. Each avatar includes predefined logic for managing its physical modules, while also providing easy data exchange with PLCs through function blocks. Avatarsinclude pre-configuration of the available protection functions.

Information accessible through the avatar includes the following:

Control data
Advanced diagnostics data
Asset management data
Energy data
