MEWTOCOL
Master/Slave Communication
5.3.2 Precautions When Using TCP Client Mode
Connection request will be performed when data transfer is executed. Please execute
master communication command after confirming the connection status flag (X30) is OFF.
When a connection successfully established, connection status flag (X30) turns ON. If a
connection failed, connection status flag (X30) stays OFF and TCP client connection failure
flag (X32) turns ON. Please reconfirm the conditions of destination or connection.
If it needs to continue data transfer between the same connected equipment , please
execute master communication command after confirming the connection status flag (X30) is
ON.
