AAC20 - Points - Random change of digital outputs state

Issue

AAC20 digital outputs change their state to default at random time intervals.

Possible cause and solution

The cause to this problem is an activated Watchdog function in the ModbusTCPSlaveNetwork, which automatically sets the DO to the default state, when the TCP communication is interrupted or the client device in the network stops responding.

Solution

In the case of the unstable communication, which results in often interruptions of the connection, the most effective solution is to switch the Watchdog function in the ModbusTCPSlaveNetwork (set 0 in the Watchdog slot).
