User Instructions

• Stator Winding Temperature

• Stator Current
NOTE:
If some of these operating conditions are not read from Modbus, then
some of the EV Triggers cannot occur. Refer to Section 4.6 for EV Trigger
details.

For each Operating Condition, the following information is needed:

Parameter Notes
The unit being measured; i.e., “MW” or “kA”.
Unit If “disabled” is selected as a unit, then that Operating Condition will not
be read.
The IP address of the Modbus data source.
IP Address
This is supplied by the customer.
The IP port number used to connect to the Modbus data source.
The default value of 502 will be correct in most cases.
Port
If a non-standard port number is needed, then the correct port number
will be provided by the customer.
The communication timeout used when establishing the connection to
Timeout the Modbus data source.
The default value of 500 ms will be correct in most cases.
This determines the function code of the Modbus register.
The default value of F03 Holding Register will be correct in most cases.
Function Code
If a different function code is required, then the correct code will be
provided by the customer.
This determines the data type being read from the Register Address;
Data Format i.e., ‘Signed 16-bit Integer” or “Float”.
This is provided by the customer.
This is used when multiple Modbus slave busses are connected to the
same IP address.
Slave ID
The default value of 1 will be correct in most cases.
If a different Slave ID is required, it will be provided by the customer.
Register Address This is the Modbus register address; it is provided by the customer.
This is the translation formula used to convert the raw Modbus data to
Formula the Unit selected.
This is provided by the customer.

NOTE:
If using a Remote I/O Unit, then the ASIM/DSIM configuration will be a
more collaborative effort; it will depend on the exact Remote I/O Unit
assembly, which analog signals are connected to which inputs, and the
translation from the analog signal to the actual Operating Condition being
measured.
