Name Declaration Type Description
CONTROL IN_OUT BYTE Divided byte with RECEIVE handling block:
SEND (bit 0 … 3), RECEIVE (bit 4 … 7).
*) Parameter is available until the FB is called.
Request - Send release:
n With a positive edge on input REQ the transfer of the data is triggered.
n Depending on the number of data, a data transfer can run over several program
cycles.
Synchronous reset:
n For the initialization SEND is once to be called in the start-up OB with every param-
eter and set R.
n At any time a current order may be cancelled and the FB may be set to initial state
with signal state "1" of R. Please regard that the data, which the CP has already
received, are still sent to the communication partner.
n The Send function is deactivated as long as R is statically set to "1".
Peripheral address:
n This parameter is only available in CPUs from VIPA or in S7-300 CPUs from Sie-
mens.
n With LADDR the address of the corresponding CP may be determined. This is the
address, which you have assigned via the hardware configuration for the CP.
HW identifier:
n This parameter is only available in S7-1500 CPUs of Siemens.
n Enter at HW_ID the HW identifier, with which your module can be addressed accord-
ingly.

Data block number:
n Number of the data block, which contains the data to send.
n Zero is not permitted.
Data byte number:
n Number of data byte in the data block, starting from which the transmit data are
stored.
Length:
n Length of the user data to be sent.
n It is: 1 ≤ LEN ≤ 1024.
