Synchronous reset:
n For the initialization RECEIVE is once to be called in the start-up OB with every
parameter 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.
n The Receive 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 are read.
n Zero is not permitted.
Data byte number:
n Number of data byte in the data block, starting from which the received data are
stored.
Size I/O area:
n Enter the size of the I/O area. Depending on the host system the CP occupies for
input and output the following bytes in the I/O areas:
– PROFIBUS: 8byte, 20byte or 60byte selectable
– PROFINET: 20byte or 60byte selectable
– CANopen: 8byte
– EtherCAT: 60byte
– DeviceNET: 60byte
– ModbusTCP: 60byte
Length:
n Length of the user data to be sent.
n It is: 1 ≤ LEN ≤ 1024.
n New received data are ready for the CPU in the CP.
ERROR:
n is set at order ready with error. Here STATUS contains the corresponding error mes-
sage.
