Two-Wire Connection
The two-wire connections states are shown in Figure 3.
Figure 3. Two-wire input connections.
Operation
A two-wire connection requires a jumper between
ON
and
COM
, which results in a default value of
ON
. If the switch
(AB) is open the state is
ON
and if it is closed the state is
OFF
.
Momentary Inputs
The following rules apply to momentary inputs:
• All state-changing pulses must be sustained for 100
milliseconds or more.
• A multistate (MI) object must be used to determine
which of the two states the input is in.
• This input configuration can generate two valid and
distinct states using digital values 0 and 4096,
representing 0 V and 5 V. A transition from
OFF
to
ON
state of the MI object toggles the corresponding
BV object. For example, changing the MI115 object
from
OFF
to
ON
toggles the BV115 object.
Maintained Inputs
A multistate object (MI) can be used to capture the
ON
and
OFF
states.
Viewing and Editing Switch
Status
The handheld LCD Programmer, cat. no. GLCHPK, can
be used to view and manually edit switch status. See
DEH41088, LCD Programmer Quick Start Guide, for a
description of the operation and menu sequence.
The available switches are listed in Table 2.
