Known Bugs

• Modbus Master Poll Time in Comfigurator 3.13.7 has been iactivated in this firmware but the defaylt value is 12 seconds polling cycle so it causes the Polling time for Modbus master to be very slow
• If the Parity does not match the correspodning Modbus device, rubbish characters are received
• Modbus Slave bug - if the external Modbus master polls the slave Holding register very fast, it may hog the Comfort RS485 Bus and prevent proper communication with other modules. Fixed 30/8/22

Bugs fixed

• Fixed Bug did not handle overflow in modbus message
• Fixed bug that modbus master processes the wrong reply after query new line

Changes

• Dont read new modbus message if current message is not processed
• If modbus reply to Master  does not match, turn on ERR LED. If reply matches, turn off ERR LED
• Modbus _master does not query the next line before reply is received
• Added queue  when there is write modbus for master, instead of send to modbus  direct which may cause collissions
