Contacts       

A contact represents an action or condition. You can link it to any of the following bit operands:

• Memory Bit

• System Bit

• Network System Bit

• Network System Input

• Inputs

• Output

• Timer

Each contact condition in a net is loaded into the bit accumulator and evaluated to determine the coil (output or expression) condition. There are 4 types of contacts:

• Direct Contact

• Inverted Contact

• Positive Transition Contact (Rise or One Shot)

• Negative Transition Contact (Fall)

Contacts can be connected in series and in parallel on a Ladder net.
