Hello !
I connect to a wago device using modbus TCP connection. When I try to perform write operation after this connection is idle (no read/write) for certain period of time, I get the “Broken Pipe” error.
As I am using wago for the first time, I don’t know how I should configure it to maintain a healthy connection, even after the connection is idle for some time.
I just had one doubt, does the KeepAlive probe resets TCP connection timer?
Suppose, Keepalive probes are being sent every 5 minutes.
The TCP timeout is 20 minutes.
Suppose I did a write at 10:00 and then the connection was idle for 20 minutes.
So, Keepalive probe was sent 4 times.
So, if no read or write was performed between 10:00 to 10:20, would the connection be considered idle and break due to TCP timeout, or would it consider Keepalive probes as some activity?
