The S7 Request Decoder module allows the acquisition of up to 1024 digital signals sent as a maximum of 64 words (16 Bit). This module type is suited for applications where large amounts of digital signals have to be acquired and for which the max. 512 directly addressable digital values of the ibaBM-DPM-S are not sufficient.
