Problem with Point Status in Watch screen

ScadaBR - Dúvidas e Suporte
1

Trying to get ScadaBR to work with Open PLC . Simple ladder logic program running on ESP32. Three outputs (coils) , one input contact . Close input contact to initiate timing sequence for 3 coil outputs. Works fine with OpenPLC with switch and LEDS’ connected .Connecting to ScadaBR via Modbus IP .Scada running on PC with Wifi connection to ESP32 again via Wifi connected to the same network router . In ScadaBR have good connection , can read coils in Data Sources window correctly , however we are not able to see the information being read correctly in the Watch window .Points are configured . We set the update period to 1 second on the Data Source window . We have an on/off switch configured in ScadaBR to control the switch contact . This is working . It starts the timing sequence on the ESP32 correctly . We expect the status of the three coil outputs to be updated in the Watch window ,but this does NOT work . The Points status configured for the 3x coils in the Watch window do not change even when we see the LEDS connected to the ESP32 output turn on or off or the coil data change in the Data Source window .We need to disconnect and re connect the Data Source to get it to update the coil status correctly in the Watch window .User Profile is set to Read all Points ,Why does the Watch window not show the changing state of the 3x coils ? I would be grateful if you can help let me know what the problem is here ?

Please answer these questions so we can help you better:

  1. What version of ScadaBR are you running (1.0, 1.1, 1.2)? And what version of JDK are you using (6, 7, 8…)?

  2. Does this problem only appear for Modbus addresses in the range (3xxxx)? That is, have you tested the other Modbus ranges and did they work as expected?

  3. If you can provide screenshots, they will be very useful to understand the problem you are facing.

  4. Please, if you have not tested other Modbus ranges as asked in item (2), try creating a virtual data point, binary type, with alternating update value and update period of 5 seconds. Check if this data point is updated in the watch list or if the entire list is frozen.
