NOTE:
Other switch combinations are NOT ALLOWED.
Profibus termination
Profibus segments should be terminated by a bus termination. The MM200 termination
voltage is +5V and the connections are as follows:
Figure 3-2: Profibus termination
If the bus voltage level is higher, such as 24V, an external device must be used to drop the
voltage to the re5V termination level. The Procentec T1 Terminator or equivalent is
suitable to provide proper termination to the MM200 from a 24V level.
Profibus DP-parameterization
The MM200 relay supports mandatory parameterization. The relay keeps its user
parameter data / setpoints in non-volatile memory and does not need device related
parameterization during startup of the DP master. The EnerVista MM200 Setup software is
the best tool for user parameterization of the MM200 device.
