9. Release list of foreign devices
In general all PROFIBUS DP slaves can be actuated
wireless. Some older Simatic S5 we find incompatibilities
which
causes in unexpected bus errors, or hanger loop of the
PROFIBUS interface in the PLC. Here only cold starts of
the PLC can help.
For Simatic S7 there are no incompatibilities known.
If you connect Simatic HMI like OP or TP keep in mind that
there is a big difference in amount of PROFIBUS telegrams
which are generated and transferred via the radio link, where
your data are located in the PLC. W e recommend to place all
transferred data on a common block which could be
transferred in one telegram via the radio. Otherwise the
actualization time will be very slow.
