Coil; Negated Coil; Creating Ld - Satec Expertmeter PM180 Reference Manual

3.10.5 Coil

Coil represents a normally inactive coil, energized whenever its rung is
closed. (Inactive at rest)
It has 2 pins:
 Input pin (left pin) - can be attached to contact, negated contact,
built-in function block, input variable, input-output variable.
 Output pin (right pin) – can be attached only to right rail.
Multiple connections are allowed.
Coil can be created only from an output variable or a local variable.

3.10.6 Negated coil

Negated coil represents a normally active ("not") coil, energized
whenever its rung is open. (Active at rest)
It has 2 pins:
 Input pin (left pin) - can be attached to contact, negated contact,
built-in function block, input variable, input-output variable.
 Output pin (right pin) – can be attached only to right rail.
Multiple connections are allowed.
Negated coil can be created only from an output variable or a local
variable.

3.10.7 Creating LD

Let's create a simple ladder diagram that contains several contacts and
coils.
To create a contact you need to drag-and-drop a variable to the
workspace.
