9.4 Copying the initialization data when replacing a positioner
● Electropneumatic positioners can be replaced in a running system without interrupting the
process.
● By copying and transferring the device and initialization data, it is possible to commission
a replacement positioner without needing to initialize it.
● An electropneumatic positioner uses the communication interface to transfer data.
NOTICE
Deferred initialization
Initialize the replacement positioner as soon as possible. The following properties can
be ensured only after initializing:
• Optimum adjustment of the positioner as per the mechanical and dynamic properties
of the actuator.
• Unrestricted accuracy and dynamic behavior of the positioner.
• Deviation-free position of the hard end stops
• Correctness of the maintenance data
