Derivation of parameter values for free slave assignment
41587
The following table shows the derivation of parameter values for a free assignment of slaves within the
analogue areas.
A free assignment of analogue slaves in slots 9...12 can only be applied if the parameters
[C.Analogue channels IN] and [C.Analogue channels OUT] are set to the value
4 channels !

AS-i 2 AS-i 1 Reserved Slave address (1...31)
Legend:
Master:

AS-i Master 1 = 0x40

EDS-file
41503
The EDS file ( E lectronic D ata S heet)is used to easily integrate the AC1423/24 in a fieldbus projecting
software. The EDS supplies a profile of the fieldbus device in form of an ASCII file. It describes all
features of the device such as communication parameters and objects.
The EDS file is saved in the device. It can be downloaded directly to the configuration PC via the web
interface (
