General
The UMG604 / UMG605 / UMG508 / UMG511 offer a variety of communication options. The following
protocols are offered on the interfaces: Modbus RTU, Modbus TCP/IP, Modbus over TCP/IP (Modbus
Gateway), BacNet or Profibus DP V0. This description of functions is a supplement to the handbook
and describes the necessary setup stages of the respective function step-by-step. More functional
descriptions can be found on

. All measurement values that the Power Analyzer
provides can be incorporated in a profibus profile. Additionally, it is possible to create personally
defined variables through graphic programming; the user-defined variables can be allocated to a
profibus profile. The Power Analyzer provides 255 profiles, whereby the first 16 profiles are prepared
for the fixed configuration. Profiles 16 to 255 can be created and occupied in the graphic
programming. There is read and write access to the profile which makes it possible to describe digital
outputs or user-defined variables from the PLC. The description of functions has been created with
GridVis 1.6.0 and with UMG604 Firmware 1.095 (available from November 2009).
Plug Assignment
The Power Analyzer supports Profibus DP V0 to 12Mbaud. The profibus connection of the Power
Analyzer is designed as a 9-pole sub D socket. We recommend a 9-pole profibus plug (type:
SUBCON-PLUS-ProfiB/AX/SC manufacturer: Phoenix art. no.: 2744380 or equivalent) for connection.

Connecting the Bus Cables
Always connect the incoming bus cable to the 1A/1B connections (including at the start of the bus
system!) The continuing bus cable is always connected to the 2A/2B connections. The terminator
resistors are activated at the start and end of the bus system using the slide switches. The connection
clamps (2A/2B) are simultaneously switched off for the continuing bus cable.
