'Insert' 'Contact' in LD
Symbol: Shortcut: +
Use this command in the LD editor in order to insert a contact in front of the marked
location in the network.
If the marked position is a coil or the connecting line between the contacts and the
coils, then the new contact will be connected serially to the previous contact
connection.
The contact is preset with the text "???". You can click on this text and change it to the
desired variable or the desired constant. For this you can also use the Input Assistant.
Regard the possibility of entering an address instead of the variable name, if this is
configured appropriately in the 'Function Block and Ladder Diagram Options' (see
Chapter 5.4.1: Comments, Linebreaks, 'Extras' 'Options').
Also in the options dialog you can activate the options Comments per Contact and
Lines for variable comment and reserve a certain number of lines for the variable
name. This might be useful, if long variable names are used, to keep the network
short.
Also regard the option Networks with linebreaks, which you also can activate in the
Ladder Diagram Options.
'Insert' 'Contact (negated)' in LD
Symbol: Shortcut: +
This command inserts a negated contact. The same is true as for the commands
'Insert' 'Contact' and 'Extras' 'Negate', which in combination also could be used to
insert a negated contact.
