Overview Quick Start When OMWT-SOFT-OPC is run for the first time it displays this help screen. You may view this help screen again by selecting "Help" from OMWT-SOFT-OPC's main window. OMWT-SOFT-OPC is designed to gather data from sensors. OMWT-SOFT-OPC makes available the data it receives from each sensor through OPC tags. The main OMWT-SOFT-OPC Server window will show the total number of devices in the startup list and how many of those that are online. The offline devices will be

Description OMWT-SOFT-OPC is a data acquisition OLE for Process Control (OPC) server that acquires data from devices and passes this data using OPC to a client application. OMWT-SOFT-OPC waits for the device to transmit and then processes the transmission. Any Windows® application that can use OPC can obtain this data from the OMWT- SOFT-OPCServer. Examples of such applications include Wonderware® Intouch, National Instruments® LookOut, Capital Equipment Corp.® TestPoint, and general

If you click that button, OMWT-SOFT- OPC will stop listing devices in the window. When you click on the "Stop" button it becomes a "Receive" button. If you click on that, OMWT-SOFT-OPC will start receiving packets and listing devices again. When you are ready, hit "OK", or "Cancel" to exit.

Polling For a wireless device the polltime has a slightly different meaning. OWMT-SOFT- OPC does not actively poll wireless devices. Rather, it waits to receive a packet from the devices. Therefore, the polltime is how often OWMT-SOFT-OPC expects to receive a packet from the wireless devices. The polltime for a wireless device is configurable during device setup. OWMT- SOFT-OPC will use this time to determine when to mark a device offline. OWMT- SOFT-OPC has a INI file parameter called "T

What is OPC? OLE for Process Control (OPC) is a specific specification of Microsoft’s Object Linking and EmbeOPCding (OLE) and Component Object Model (COM) that is administered by the OPC Foundation (150 member companies including Microsoft Corporation). OPC provides a common interface for devices and applications to communicate. Devices that gather or originate data become OPC servers, providing data to OPC client applications in a consistent fashion. At the heart of OPC is the client/

OMWT-SOFT-OPC Main Window Main Window OMWT-SOFT-OPC displays the number of devices online and offline. It also lists the devices that are currently offline displaying the name and serial number of the device. If OMWT-SOFT-OPC is running with TCP/IP receivers, then for each offline device it will display the node address, name and serial number of the device. Setup OWMT-SOFT-OPC simplifies setup by automatically finding, identifying and beginning to poll devices in a network. OWMT-SOFT-OP

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

Train The Train dialog is used in the processing of training the Output device to output packets (as produced by OWMT-SOFT-OPC). Follow these steps to train an Output device: 1. Select the desired Output from the list of Outputs. 2. Press and hold the button on the Output device (label as “train”). 3. Click the button on the Train window. Repeat until the LED on the Output device is on. The Output device is now ready to receive Output packets from OWMT-SOFT-OPC. 12 x OMWT-SOFT-OPC Main W

Follow the setup procedure to add more devices. The setup screen is the method by which OWMT-SOFT-OPC acquires wireless devices. The default on the setup screen is to accept only packets that are sent in service mode from the device (the packet is sent by pressing the service button on the device.) To change t

OMWT-SOFT-OPC Server .INI File Format OMWT-SOFT-OPC.ini The OMWT-SOFT-OPC.INI file contains the configuration parameters for the server and the devices being polled. When OMWT-SOFT-OPC searches and finds a new device it adds the device to the INI file and assigns default initial parameters. These parameters can be changed by using a text editor and editing the INI file, or by using the included OMWT-SOFT-OPC.ini Editing Utility, which will be discussed later in this Help. (The installat
