In the table above, while there are only two LEDs, the LED labeled BF acts as both the Active and BF LED.
C445 Cyclic (Polling)
The most common way of exchanging data with the C445 is
via cyclic messages from a PROFIBUS master. The master
sends control data to the C445 and reads monitoring data
from the C445. Typically the control information involves a
single or more bytes to instruct the C445 to run the motor or
reset a fault. Data read from the C445 typically involves
running status and fault state, along with motor parameters
such as motor current, voltage, power and so on. The GSD
file for the C445, available from the Eaton website defines
the cyclic modules used to read and write to a C445 by the
PROFIBUS master. The GSD file is installed into the
PROFIBUS master’s programming software and used to
configure the master for the data it will exchange with the
C445.
The following are the various modules from the C445
GSD file:
Select a maximum of 2 cyclic modules, as long as only one of
them includes output/control words. A maximum of 8 control
words from any one cyclic module containing output data is
allowed.
Each module contains a different number of input and output
bytes. There are 15 different Modules, where any 1 or 2 of
these modules may be selected for each C445.
Module 1
: Motor Management Profile as per IEC 61915-2,
Command format 200 and Monitor Format 200
This profile is the only one that does not have
selectable data. The I/O data is fixed. This profile
includes the following:
Output data: The Motor Control Word (2 bytes).
Input data: The Motor Status word and Average
Current Scaled (4 bytes total).
The Motor Control Word is defined as follows.
Bit 0: Run Reverse
Bit 1: Reserved
Bit 2: Run Forward
Bit 3: Reserved
Bit 4: Reserved
Bit 5: Reserved
Bit 6: Reset
Bit 7: Reserved
Bits 8-15: Reserved
The Motor Status Word is defined as follows:
Bit 0: Running Reverse
Bit 1: Reserved
Bit 2: Running Forward
Bit 3: Overload Warning
Bit 4: Reserved
Bit 5: Reserved
Bit 6: Fault
Bit 7: Warning
Bits 8-15: Reserved
