Cyclical data traffic

The master class 1 (e.g. PLC) cyclically reads out measured values from the sensor during opera-

tion. The below block diagram below shows which data can be accessed by the PLC.

Module of the PA sensors

For the cyclic data traffic, VEGACAL 62 provides the following modules:

•

AI (PA-OUT)

– PA-OUT value of the FB1 after scaling

•

Additional Cyclic Value

– Additional cyclical value (depending on the source)

•

Free Place

– This module must be used if a value should not be used in the data telegram of the cyclical

data traffic (e.g. replacement of the Additional Cyclic Value)

A maximum of three modules can be active. By means of the configuration software of the Profibus

master you can determine the configuration of the cyclical data telegram with these modules. The

procedure depends on the respective configuration software.

Note:

The modules are available in two versions:

•

Short for Profibus master supporting only one "Identifier Format" byte, e.g. Allen

Bradley

•

Long for Profibus master only supporting the "Identifier Format" byte, e.g. Siemens

S7-300/400

Examples of telegram configuration

In the following you will see how the modules can be combined and how the appendant data tel-
