I have an RTU with modbus serial interface and I would like to use Mango to control it. I am a novice with Scada but I have successfully installed and used Mango to flip some binary outputs on the RTU without much problem. I have a couple of issues that I need help with:
- I created 2 data sources, 1 for my RTU and 1 Virtual, and I added some points for both and used a watch list to monitor them. When I set a binary output of the modbus serial device to 1, the value on the watch list changed to 1 and I verified that the output on the RTU is now high. After a short moment, the watch list is automatically refreshed and the value on the watchlist is set back to 0. The output on the RTU remains unchanged. I do not see the same problem with I repeat the same procedure for a point of the virutal data source.
- I installed mango on a PC running linux with 2 serial ports, /dev/ttyS0 and /dev/ttyS1 and the modbus serial device is connected to /dev/ttyS0. When I first created the data source, the port option allowed me to select either /dev/ttyS0 or /dev/ttyS1 and I selected /dev/ttyS0 and the data source is properly created. When I went back to edit it however, the port is now shown as connected to /dev/ttyS1 and the option /dev/ttyS0 is also gone.
The 2 problems above occurred on both versions 1.7 and 1.8. I have also changed from Derby to mysql with no improvements.
I also have a minor problem with 1.8. With first attempt to login, it will complain with
"NOTE: you may have problems with Mango because your browser is not officially supported. Please upgrade your browser". I am using the latest release of Firefox, 3.5.3. I do not have that problem with 1.7
