Communication System Manual
3.5.3.4.1 Position of cyclic part of message
Because applications such as WinCC can only access SIMATIC S5 data blocks via FDL link, for
example, the cyclic part of the message must be inserted in the DB. The cyclic input bytes are stored in
DW96 and 97 of DBAT and the output bytes in DW98 and 99. These can be used to poll the cyclic
messages and to switch the circuit-breaker on and off. The program resets the bits for switching on/off
after 250 ms.
3.5.3.4.2 Enabling and priority assignment of acyclic requests for
operational data to be read cyclically
