 CONTACT INPUTS

The present status of the contact inputs is shown here. The first line of a message display indicates the ID of the contact
input. For example, 'Cont Ip 1' refers to the contact input in terms of the default name-array index. The second line of the
display indicates the logic state of the contact input.
