Ethernet connection via TCP protocol3
Principles3.1
The data of the TCP connection is transmitted as a data flow, i�e� there is no
defined start or end character on the protocol level�
The returned data is received byte for byte and stored in the receive buffer�
For communication via Ethernet, all TCP protocol compatible Ethernet CPs can be
used�
However, the different selection of the Siemens communication blocks when using
controllers of the 300 or 400 series is to be taken into account�
The communication was tested with a CPU 414-2DP and a CP 443-1�
Set-up of the multicode reader3.2
Select Global device settings → Process interface → Selection of the process ►
interface → TCP/IP.

Setting parameters on function block FB503.4
Indicate ID and LADDR as set up in Net-Pro�►
(Are forwarded to the communication function blocks�)
The parameter RECV_BUF must be declared as absolute, because with
some controller types the width of access may not be transmitted correctly
in case of symbolic declaration�
Description function block FB503.5
The function block establishes the telegrams to be sent to the multicode reader
and creates a character string from the received data flow�
The "trigger" input sends a trigger command to the multicode reader with each
positive edge� In addition the receive buffer is deleted�
The "change_group" input sends a change group command to the multicode
reader with each positive edge� The selection is indicated at the "group_nr" and
"conf_nr" inputs� In addition the receive buffer is deleted�
The "read_conf" and "read_stat" inputs send the corresponding status query to the
multicode reader with each positive edge� In addition the receive buffer is deleted�

11
The received data is read byte-by-byte from the data flow and then stored
consecutively in the receive buffer�
The length of the receive buffer is defined variably as ANY pointer and can be
extended or reduced according to the respective requirements�
The character string received from the configuration software after the start and
end characters have to be evaluated externally�

Serial connection via ASCII driver4
Principles4.1
The received data is received byte for byte and stored in the receive buffer�
All PtP CPs with ASCII protocol driver can be used for serial communication� In
that case, however, the transmitting and receiving function blocks used in FB49
have to be adapted accordingly�
The communication was tested with a CPU 414-2DP, a CP 440 and an RS-485/
RS-232 interface converter�
Set-up of the multicode reader4.2
Select Global device settings → Process interface → Selection of the process ►
interface → "Serial".

Set-up in step 74.3
Set up an ASCII coupling for the corresponding CP and define the telegram►
length 1 byte�
All other settings depend on the CP used�
Below as an example the setting of a CP 440 with interface converter:

Setting parameters on function block FB494.4
Enter parameters for the CP address�►
(Are forwarded to the communication function blocks�)
The parameters SEND_DB_BUF, SEND_DBB_NO, RECV_DB_BUF und
RECF_DBB_NO are the start addresses for an intermediate buffer needed for this
coupling�
The parameter RECV_BUF must be declared as absolute, because with
some controller types the width of access may not be transmitted correctly
in case of symbolic declaration�
Function block description FB494.5
The function block establishes the telegrams to be sent to the multicode reader
and creates a character string from the received data flow�
The "trigger" input sends a trigger command to the multicode reader with each
positive edge� In addition the receive buffer is deleted�
The "change_group" input sends a change group command to the multicode
reader with each positive edge� The selection is indicated at the inputs "group_nr"
and "conf_nr"� In addition the receive buffer is deleted�

The "read_conf" and "read_stat" inputs send the corresponding status query to the
multicode reader with each positive edge� In addition the receive buffer is deleted�
The received data is read byte-by-byte from the CP and then stored consecutively
in the receive buffer�
The length of the receive buffer is defined variably as ANY pointer and can be
extended or reduced according to the respective requirements�
For the serial coupling there is an additional intermediate buffer for the telegram
to be sent and the telegram to be received� Stored here in DB200, parameters
can be set at the inputs SEND_DB_BUF, SEND_DBB_NO, RECV_DB_BUF and
RECF_DBB_NO�
The character string received from the configuration software after the start and
end characters have to be evaluated externally�
