6.4.4 Submodule Preset (adjustment function)
Danger of physical injury and material damage due to an actual value
jump during execution of the adjustment function!
 The adjustment function should only be executed when the measuring
system is stationary, or the resulting actual value jump must be
permitted by both the program and the application!
6.4.4.1 Structure of the cyclic process data
With the submodule Preset, a 32-bit adjustment value can be transmitted and set as new actual
position value via the cyclic I/O output data. The adjustment value must be within the programmed
measuring range –1. If an invalid adjustment value is transmitted, the adjustment is not accepted and
error code 0x80 is indicated in the status byte. The error code in the status byte is deleted again with
control byte = 0x00.
The adjustment value is set with a rising edge 0->1 of bit 2
0
(0x01) in the control byte. Execution of the
adjustment is acknowledged in the status byte by setting bit 2
0
(0x01). By resetting bit 2
0
(0x00) in the
control byte, bit 2
0
(0x00) in the status byte is also reset automatically.
