Hi,
I'm using a read_var command on a Schneider M340 PLC to communicate with another M340 PLC in the network.
The communication is working fine most of the time, but once in a while (every hour or so) I get an error (number 0x07 = Generic transmission interruption ) and the read_var fails.
If this error occurs, it remains for several retries, and then after a while (without doing anything special, other than retrying) the communication is back on again.
I must mention the communication channel between the two PLCs is stable all the time with/without the read_var error (a ping test does not show any timeout).
Anyone familiar with this error?
Your help will be much appreciated.
Regards,
Assaf
