2 Integrating the Module in PROFIBUS-DP

Function blocks for SIMATIC S7

Function blocks for
SIMATIC S7

The FBSENDRSXXX, FBRECVRSXXX and
FBSRRSXXX function blocks are designed for the
SIMATIC S7 (Siemens) PLC system and
PROFIBUS-DP. The function blocks control the
data exchange between the PLC and the
XN-1RS232 module. The transfer format is 8 bytes
in length, consisting of 2 bytes of control data and
6 bytes of user data.

The data range of the data bytes to be transmitted
or received within the Siemens S7 PLC is optional.

Data sets of up to 65526 data bytes can be trans-
ferred, depending on the capability of the PLC.

The system function blocks SFC14 and SFC15
from Siemens are used in order to ensure consis-
tent data exchange. The return values are trans-
ferred transparently, and the meaning of the error
numbers can be obtained from the manual
“System software for S7-300/400”.
