I have an issue with the use of multiple Modbus-Flex-Getter nodes.
I am working with raspberry pi 3b+ and use following software versions:
I have expanded my project to communicate now with 3 solar inverters and 1 energy meter, on basis of modbus-tcp. As I said I use modbus-flex-getter for data collection. For every connection I have configured a separate modbus-server configuration.
My problem is as follows, now that I have increased from 3 to 4 connections, there is always 1 that is not reading data for some reason. Every time I restart node-red. There is only 3 connections reading data, the one not reading data is quit random. I also tried decreasing polling time from 1 sec to 10 sec, but that doesn't seem to be the cause. The connection that's not reading data, cycles through:
->reconnect->initialize->connected->queuing .... and back again.
My question is, is there some sort of limitation on the number of connections you can make, or is there another cause for this problem?
