UMG 508Profibus profileA Profibus profile contains data to be exchangedbetween a UMG and an SPS. Four Profibus profilesare pre-configured in the factory.With a Profibus profile, you can:• call-up measurement values from the UMG,• set the digital outputs in the UMG,• request the status of the digital inputs in theUMG.Each Profibus profile can contain a maximum of127Bytes. You can apply further Profibus profilesif more data has to be transferred.• Each Profibus profile has a profile number.The profile number is sent by the PLC to theUMG.• You can directly process 16 Profibus profileswith GridVis (profile numbers 0..15).• Additional Profibus profiles (profile numbers16..255) can be applied using Jasic programs.• Factory pre-configured Profibus profiles canbe subsequently changed.Device master fileThe device master file, abbreviated with GSDfile, describes the Profibus characteristics of theUMG508. The GSD file is required by the PLCconfiguration program.The device master file for the UMG508 has thefile name "0C2C.GSD“ and is contained on thedata carrier supplied with the delivery.Variable definitionAll system variables and global variables 1) canbe scaled individually and converted into one ofthe following formats:• 8, 16, 32Bit integer with and without sign.• 32 or 64Bit float format.• Big or Little Endian.Big-Endian = High Byte before Low Byte.Little-Endian = Low Byte before High Byte.1) Global variables are variables that are defined bythe user in Jasic and are provided to each interfacein the UMG508.76
UMG 508ExampleCollect measurement values using ProfibusYou must transfer at least one Profibus profilewith GridVis and transfer it to the UMG508.A Jasic program is not necessary.Illu. Block switch diagram for data exchange between PLC and UMG508.77
