UMG 96RM-P/-CBM
Profibus interface (only UMG 96RM-P)
Profibus profiles
A Profibus profile contains the data to be exchanged
between a UMG and a PLC. It is possible to read out
measurement values and statuses via eight user-defined
and four factory pre-configured Profibus profiles.
A Profibus profile can:
• Retrieve measurement values from the UMG.
• Set the digital outputs in the UMG.
• Query the status of the digital inputs in the UMG.
Each Profibus profile can hold a maximum of 127 bytes
of data. If more data has to be transferred, simply create
additional Profibus profiles.
• Every Profibus profile has a profile number.
The profile number is sent by the PLC to the UMG.
• The 8 user-defined Profibus profiles (profile
numbers 0...7) can be edited with the GridVis
software.
• Factory pre-configured Profibus profiles (profile
numbers 8...11) cannot be changed.
Activate outputs/tariffs via Profibus
To set the outputs or the tariffs an appropriate profile must
be selected. Alongside the 1st byte used for the profile
selection three further bytes can be used to:
• Switch outputs
• Control tariffs and energy meters
Profile number selection (1st byte):
Byte 1 enables the selection of the Profibus profile
number 0 to 11. The output range of the PLC must
contain this byte as a minimum. Within the byte, bits 0
to 3 describe the profile number, bits 4 to 7 are unused.
Switching digital outputs (2nd byte):
Setting or clearing the bits in byte 2 ("Profibus remote"
type) enables the setting of the digital outputs 1-6. Bits
6 and 7 are not used.
Example:
Profile number 8 selected
