Outputs
Outputs are only send packets. The Output devices do not send packets. Therefore
the setup for an Output sensor must be done manually. Some Outputs need to be
“trained” to the packets that it will receive for from the Server.
New and Edit
Create or edit an Output object to manage an Output sensor. The following
describe the parameters necessary to set up an Output sensor.
Type – “Dual Discrete Outputs” or “12 bit Analog Output”. Select the type
of Output sensor. Note changeable only for the Edit Output window.
Serial Number – Some Outputs sensors can “learn” a serial number. Others
have the serial number preassigned and must be entered in the field.
These sensors have the serial number labeled. For those sensors that
must learn their serial number, OWMT-SOFT-OPC creates a default
serial number. Press the “Generate New Serial Number” button to
generate a new serial number.
Label – name assigned for this Output sensor. The label name is used for
the OPC topic name. This name must be unique. For the Edit Window,
the Label field contains a list box. Select the Output to modify from the
list. You can also change the label for the current Output.
Node – This field applies only when using the OMWT-RECIP Receiver.
The Node List box contains a list of the OMWT-RECIP Receivers to
send the output packet to. For the“Send All” selection, OWMT-SOFT-
OPC sends the packet to all the OMWT-RECIP Receivers.
Dual Discrete Outputs
Send when output B is written – If checked, OWMT-SOFT-OPC will only
send the output packet only when the “outputB” item is written to (OPC
poke). Output A is first written to and the output B. If unchecked,
OWMT-SOFT-OPC will send the output packet when either the
“outputA” or “outputB” items are written to (OPC poke). The state of
both outputs is sent in the same packet.
12 bit Analog Output
Scale – the scale to apply to the raw reading (12 bits: 0 to 4095).
Offset – the offset to apply to the reading after the scale is applied.
Engeering Value = Scale * raw + Offset.
Units – units label for the analog output.
