What do the colors in the I/O Monitor Window of OmniServer mean?
The window called I/O Monitor in the OmniServer Universal OPC and I/O Server allows you to monitor the state of communications using your custom protocol.
This is primarily intended as a debugging and test tool. The data in the window is shown in color codes. What do those color codes mean?
The color codes are as follows:
- Black - Data sent out by OmniServer to the device.
- Blue/Cyan - Data that has been received but not yet processed by OmniServer. Eventually, this data will change to Magenta, Red, or Green.
- Magenta - OmniServer could not match this data with any configured host messages in the protocol. The data has been ignored.
- Red - OmniServer matched the data to the protocol but the checksum failed.
- Green - All of the received data matched with the protocol. This is the ultimate objective, to see all green for data that has been received by OmniServer from the device.
