6.5 Parametrization
6.5.1 FC/SFC 216 - SER_CFG - Parametrization PtP
The parametrization happens during runtime deploying the FC/SFC 216 (SER_CFG). You
have to store the parameters for STX/ETX, 3964R, USS and Modbus in a DB.
6.6 Communication
6.6.1 FC/SFC 217 - SER_SND - Send to PtP
This block sends data via the serial interface. The repeated call of the FC/SFC 217
SER_SND delivers a return value for 3964R, USS and Modbus via RETVAL that con-
tains, among other things, recent information about the acknowledgement of the partner
station. The protocols USS and Modbus require to evaluate the receipt telegram by
calling the FC/SFC 218 SER_RCV after SER_SND.
