1.1 General
The Profibus DP Module (Mk2) has three versions:
Single Channel Profibus DP plus one analogue input channel
Simple Dual Channel, independent isolated Profibus DP highways for redundant systems
that do not support full RedCom
RedCom Dual Channel, independent isolated Profibus DP highways for RedCom
compliant systems
The two dual channel versions have the same physical assembly, but are configurable to include the
necessary extra messages for RedCom systems. PLCs that cannot accept the extended diagnostic
messages from RedCom slaves should use the Simple Dual channel card. The reporting of RedCom
extended diagnostics can be selected from the GSD file.
