Hello all,  
I 'm using the ignition version (7.9.9),but i have a problem with a one device ModBus TCP.  
The device always is connecting and disconnecting , but I tryed to change the configuration into the device but it doesn’t change nothing. I saw into the log the device but I have an error of the type “SockedIODelegate”.
