TC_SEND: Send data via the GSM network

Meaning
The TC_SEND instruction allows the sending of data via programmed connections of the
following types:
● ISO-ON-TCP connections
● UDP connections
● SMS connections
● Telecontrol connections
You will find more detailed information on the connection types in the description of the
TC_CON instruction.
The ID parameter references the GPRS connection. The value of ID must correspond to the
value used for ID by TC_CON.
The InterfaceID parameter references the GPRS interface of the required local CP. The
value must be the same as that used by TC_CON for InterfaceID.
The amount of data to be sent is specified with the LEN parameter.
The size of the data area specified in DATA must be at least as large as the number of bytes
configured for LEN. Permitted data types in the data area specified in DATA are all except
BOOL and ARRAY of BOOL.
