According to the documentation in the "Mango ES" heading there is a picture showing the Mango ES with the connections and on The DIP-switches it say "RS-485 Biasing and termination"
But in another thread in the forum it is stated:
"The DIP switches on the MangoES should always be in the down position. These are for future expansion so all down is the only valid config for now."
So if I am 100% of the up time is getting errors like:
"Modbus RS 485': Boost ON/OFF Device name: Modbus RS 485: Illegal data address" in spite of that it does respond in the data source menu when setting up the Modbus registers on the very same data address.
Could it be that I do need a 120 Ohm termination on the Mango ES terminals ?
Is it a noise thing or problem due to lack of termination or should I look for SW issueS?
If I delete this Data point then the next one pop up as "illigal data address"
