Normally Closed Contact
Normally closed contacts are also very common. This is accomplished with the Store Not, or
STRN instruction. The following example shows a simple rung with a normally closed contact.
Contacts in Series
Use the AND instruction to join two or more contacts in series. The following example shows
two contacts in series and a single output coil. The instructions used would be STR X0, AND
X1, followed by OUT Y0.
Midline Outputs
Sometimes, it is necessary to use midline outputs to get additional outputs that are conditional
on other contacts. The following example shows how you can use the AND instruction to
continue a rung with more conditional outputs.
