3.2.2.3 Query pasteurization progress

Introduction

The following steps show you how to control the conveyor depending on the progress of the

pasteurization process. When the milk in a bottle has been pasteurized, the conveyor is set

into motion and the bottle transported to the end of the conveyor. The information about the

progress of the pasteurization process is stored in the "milk_pasteurized" tag and queried

with the help of a normally open contact.

Requirements

● The organization block "Main [OB1]" is open.

● The conditions described in the sections "Querying the status of the machine (Page 95)"

and "Querying the position of the bottle and the status of the heating ch

amber (Page 97)"

have already been programmed.

Procedure

To control the conveyor depending on the progress of the pasteurization process, follow

these steps:

1. Insert a branch in the rung between the first and second normally open contact.
