Description: A specific GSD file is allocated to every device operating mode. If the
configuration of your PROFIBUS PA path does not match the set
device operating mode, the device cannot accept the cyclic data
exchange. The station number and the device operating mode can‐
not be modified during ongoing communication with a master of
class 1.
A successfully established connection with a cyclic master can be
detected when the positioner responds to the setpoint of the master.
A blinking decimal point in the top line of the positioner display indi‐
cates communication with an acyclic master.
Factory setting: 1
