TCP
Parameter
Possible values
Default
Description
IP address
xxx.xxx.xxx.xxx
192.168.0.43
Available only in "Client" mode.
IP address of the TCP/IP communication partner (server)
with which the reader (client) is to set up a TCP/IP con-
nection. For SIMATIC controllers, "active connection
establishment" must be disabled.
Port
Device-specific
8020
"Client" mode: Port of the TCP server.
"Server" mode: Port on which the reader waits for an
incoming connection from a TCP client.
Time limit
0 ... 3600
0
•
0: There is no transfer of cyclic monitoring frames to
test the connection to the TCP/IP connection partner.
•
Otherwise: Time in seconds after which a monitoring
frame is sent to check the connection to the TCP/IP
connection partner. The check is implemented by
sending the "Idling string" to the recipient at the con-
figured interval. If the test fails, an error is output (only
when the reader is in "Start" or "Save program" mode)
and the connection is reestablished.
Idling string
Characters whose
ASCII equivalent is
between 01H and
FFH or the format-
ting instruction %b
for generating the
binary result.
\r\n (carriage re-
turn, line feed)
Binary result of read procedure:
Byte in which the bits "IN_OP", "TRD", "RDY", "READ",
"MATCH", "N_OK" are coded according to the status
byte. The assignment is as follows:
