15. Descriptions for relevant flags during communication:
TCP MODE:
M1196=ON: Communication port is connected
 Master/Slave mode; communication is working fine.
 M1197 = ON, this indicates the communication is active. Make sure the TCP connection
is ready or is waiting to be connected and checking its relative communication settings
are set, the data length is less than 200 characters and if the slave is responding.
 After data is sent or received, M1197 stays ON and a completion flag will be set to ON.
(You can reset this flag to OFF.)
 If the ETHRS instruction is stopped, the communication will be kept and the setting of
Keep Alive Timeout will not affect the communication status.
 If the ETHRS instruction is executed again, the completion flag will be reset to OFF.
 When you set M1196 to OFF, the communication will be stopped.
 Master/Slave mode; an error occurs during communication.
 M1197 = ON, this indicates the communication is active. Make sure the TCP connection
is ready or is waiting to be connected.
 When an error occurs, M1198 is ON and the error codes will be shown in D1176.
 Execute ETHRS instruction again, after the problem is fixed, and M1198 is reset to OFF.
 If receiving time out is enabled in Master mode, it starts counting after the sending is
done.
 If receiving time out is enabled in Slave mode, it starts counting after the connection is
established.
