Supplementary Documentation IFC 090, IFC 090 i with PROFIBUS-PA General These Instructions are supplementary to the “Installation and Operating Instructions IFC 090 K / F“ dated 12/96. The details given there, in particular the Safety Information, are valid and should be observed. These Supplementary Instructions provide only additional information for device operation and connection to a PROFIBUS-PA fieldbus.

“PROFIBUS-PA networks”. 1.1 GSD All available GSD files of KROHNE devices – including those of the IFC 090, of course - are supplied together with each device. The GSD contains information that is needed for project planning of the PROFIBUS-DP/PA communication network.

If the device has been detected an error additional diagnostic information will be send to the master. The meaning of the additional information is described within the GSD file under UNIT_DIAG_BIT(i). KROHNE Messtechnik GmbH & Co. KG · Ludwig-Krohne-Str. 5 D-47058 Duisburg ...
In “Ex“ systems an adequate equipotential bonding in the hazardous and non-hazardous location along the entire fieldbus installation is strongly recommended. Multiple grounding of the shield is also of advantage. Note: The use of twisted and shielded cables is strongly recommended, otherwise EMC protection of the IFC 090 cannot be assured.
(see Section 4 in the Installation and Operating Instructions) The following settings need to be made for operation of the IFC 090 on a PROFIBUS-PA network. Note that the address can be set by the service “set slave address” as well.
