Insert a basic network
When developing an LD network, first a basic network consisting of one contact, one coil and two power rails must be inserted. Then, this basic network can be expanded by further parallel/serial contacts/coils or other graphical objects such as functions and function blocks.
FBD/LD code worksheets
- Left-click into the code worksheet at the position where you want to place the network.
- Left-click the
in-place button or the corresponding button on the editor's toolbar. Alternatively, press <F8>.A basic network with a left and right power rail and a contact and coil is inserted. Although the LD objects have identifiers (C001 and C002), no relating variables are yet declared.
- Insert/declare variables for the contact and coil as described in the procedure "Assign variables/constants to an LD object" (see below).
NOLD and SNOLD code worksheets
In NOLD and SNOLD, an entire code section is inserted with a new network, bordered by the horizontal section bar at its top.
- Left-click anywhere below the lowest existing section.
- Left-click the
in-place button or the corresponding button on the editor's toolbar. Alternatively, press <F8>.A basic network with a left and right power rail and a contact and coil is inserted. Although the LD objects have identifiers (C001 and C002), no relating variables are yet declared.
