6.7 Watch and Receipt Manager

6.7.1 Watch and Receipt Manager

With the help of the Watch and Receipt Manager you can view the values of selected variables. The Watch and Receipt Manager also makes it possible to preset the variables with definite values and transfer them as a group to the PLC ('Write Receipt'). In the same way, current PLC values can be read into and stored in the Watch and Receipt Manager ('Read Receipt'). These functions are helpful, for example, for setting and entering of control parameters.

All watch lists created ('Insert' 'New Watch List') are indicated in the left column of the Watch and Receipt Manager. These lists can be selected with a mouse click or an arrow key. In the right area of the Watch and Receipt Manager the variables applicable at any given time are indicated.

In order to work with the Watch and Receipt Manager, open the object for the

Watch and Receipt Manager in the Resources register card in the Object Organizer.

6.7.2 Watch and Receipt Manager in the Offline Mode

In Offline Mode, you can create several watch lists in the Watch and Receipt Manager using the 'Insert' 'New Watch List'.

For inputting the variables to be watched, you can call up a list of all variables with the Input Assistant, or you can enter the variables with the keyboard, according to the following notation:

<POUName>.<Variable Name>

With global variables, the POU Name is left out. You begin with a point. The variable name can, once again, contain multiple levels. Addresses can be entered directly.

Example of a multiple-level variable:

PLC_PRG.Instance1.Instance2.Structure.Componentname

Example of a global variable:

.global1.component1
