Acyclic Data
SITRANS Probe LU supports up to four simultaneous connections by a Class 2 Master
(C2 connection). It supports one connection by a Class 1 Master (C1 connection).
In order for a Class 1 Master to read parameters from an instrument, it needs to know the
slot and absolute index of the parameter.
The parameters are all listed in SIMATIC PDM under Help. If you do not have SIMATIC
PDM, you can download the DD and reference the HTML help file directly.
