Most any HMI program can use OmniServer. The key requirement is that the client program supports either one of the following transports:
- OPC
- DDE
- FastDDE
- Suitelink
If your client supports any of the transports above, then you will be able to talk to OmniServer.
For specific directions on different clients, please see the links above or click on any of the links below:
If you do not see your client listed, please contact us and we will be happy to assist you.
Generic DDE
When using OmniServer with DDE, you will need three pieces of information:
- Application Name: This is sometimes called the EXE file. You will use the name OSRVDDE (note that there is no EXE at the end. Do not append the EXE).
- Topic Name: This will be the name of the topic you defined in OmniServer.
- Item name: This will be a name of an item defined within a protocol that is associated with the topic mentioned above.
You will need to consult your software's documentaion for the exact way to use these three pieces of information. For example, if you were using Microsoft Excel, the formula you would put in a
cell would look like this:
=OSRVDDE | topic_name ! item_name
(Note: Do not use spaces. They are here in order to make the formula readable)
Generic OPC
OPC is an industrial standard method of communicating between clients and servers. When using OmniServer with OPC, you will need three pieces of information:
- Server ProgID: This will be SWToolbox.OmniServer.
- Topic name: This will be the name of the topic your defined in OmniServer.
- Item Name: This will be a name of a item defined within a protocol that is associated with the topic mentioned above.
You will need to consult your software's documentation for instructions on how to use these three pieces of information. Normally (not all the time, mind you), an OPC client will ask for
a Server Name and an Address. Given that, this would be how to setup the connection:
- Server Name: SWToolbox.OmniServer
- Address: topic_name . item_name
(Note: Do not use spaces. They are here in order to make the entry more readable).
