NZM-XDMI-DPV1
(PROFIBUS-DPV1 Interface for
DMI)
86
11/04 MN01219002Z-EN
Module 1 conform to PROFIBUS circuit-breaker
profile 1
The following information can be read out of the circuit-
breaker and DMI with the selection of this module:
• Communication to the circuit-breaker (in order, not
present),
• Switching state of the circuit-breaker
(“ON”, “OFF”, “Tripped”),
• Load warning (current
f
70 %),
• Overload zone reached (current
f
100 %),
• Group warning,
• Trip cause (e.g. overload, short-circuit, fault current),
• State of the inputs of the DMI.
In addition, the following functions can be controlled:
• Switch state of the circuit-breaker via connected remote
operator (switch on, switch off),
• State of the outputs of the DMI (for outputs whose switch
signal has been parameterized on the “Bus”).
The information read out are data inputs of the DP master,
the controllable functions are picked up in the DP master as
data outputs.
Format of the data inputs
Reading of the data inputs is implemented directly via the
DPV0 read commands or via the input bytes of the DP master
defined by the PROFIBUS-DP configuration. Note the
documentation of the master device for this purpose. Three
Octets are read as data inputs which contain the following
data:
h
If a motor starter function is parameterized in the DMI
(only possible in conjunction with the intended circuit-
breaker type -ME), please use module 3 or module 4 if you
control the motor via PROFIBUS-DP or if you wish to be
informed concerning the state of the motor control.
