Data can be transferred
between a PC and MIC 500 or
vice versa
1.3 Connecting the PC
The PC can only be connected to the first current output of the MFC 081/085, i.e. current
output from terminals (5 (–) and 6 (+). The other current outputs that may be available
(depending on options ordered) will not carry the FSK signal and the Smart system will not
work. If another communication protocol option has been ordered, e.g. RS 485 or Profibus,
then the Smart system will be inactive as the processor will only accommodate one
communication protocol at a time.
Note:
This communication protocol is a Krohne designed protocol and for use with Krohne CONFIG
Software package and not intended for use on non-Krohne equipment. The protocol
description is thus also not available for distribution.
