Introduction

This section describes the specifics of the LL984 Editor referring to modifying LL984 network properties.

For standard features please refer to Accessing Sections.

Protection

The Protection property is not available at the moment.

Localization

You can only attach an LL984 segment to a functional modules. The networks of a segment are implicitly attached to the functional module of their segment.

Condition

You can modify the Condition of an LL984 network in the Condition tab of its properties dialog.

When you configure a boolean variable in this tab, the state of this variable is checked at the beginning of the LL984 network's code execution.

When the variable´s state is 0, the variable and its networks are not executed.

When the variable´s state is 1 or when no condition variable is defined for the network, it depends on the condition variables of the networks whether the networks are executed or not.

You can define a condition variable for each network.

NOTE: Condition variables do not have influence on the execution of an L9_SKP block, that means when you have a skip over 4 networks, you skip the remainder of the current network and the next 3 networks independent of their condition variables.

Remote I/O

You can synchronize the Remote I/Os only for LL984 segments and not for LL984 networks.

Comment

You can enter a comment to an LL984 network in the Comment tab of its properties dialog.

The maximum size of a comment is 1024 characters.

User Directory/Hyperlink

For LL984 networks you can add hyperlinks by selecting Add Hyperlink from the network´s context menu.

For details please refer to chapter Hyperlinks.

You can not add user directories to LL984 networks.

LL984 Networks in Subroutine Segments

The properties dialog of an LL984 network in a subroutine (SR) segment only provides the General and the Comments tabs.

The Is called check box in the General tab is greyed and not checked, because in LL984 subroutines can be called via a memory word and so you only know at run time whether a subroutine is called or not.

You can not define a condition variable for an LL984 network in a subroutine (SR) segment.
