Create a new device | For creating a new device go to [Tools] - [I/O Devices] or click the The following picture demonstrates the first step for creating a new device.  I/O Device Name: Give a device name. This name will be used in the Tag configuration window of the database accompanied by the Station Name. |
Select a device type | After selecting [OK] on the previous step, the ‘Serial Communication Configuration’ dialog box will be popped up as shown in the following picture.  In this window, select the ‘Device Type’ as ‘DANFOSS VLT AutomationDrive FC-300’ and configure the proper serial communication parameters.

Create a station | Move to the ‘Station’ [Station] tab of the ‘Serial Communication Configuration’ dialog box.  In this dialog box, all the connected PLC stations can be configured and registered to the Xpanel. Each field can be configured as followed: Station Name: Give a name to the PLC. This name will be used in the database window accompanied with by the ‘Device Name’. Station Type: Choose the ‘FC-300’ (no other type can be selected). Network ID: This field has no effect. Station No.: Specify a number between 0 and 9. 16Bits Data Swap: This field has no effect. 32Bits Data Swap: This field has no effect. String Data Swap: This field has no effect. Using ChecksumCheckSum: This field has no effect. Comm. Error Message Pop Up: When this item is checked, Xpanel displays a communication error message box for every Rx and Tx error. Otherwise (unchecked), Xpanel does not display a message for communication errors. This message box will close automatically after a few seconds. |
Address Notation
The address of a Tag tag in Xpanel has the following format:
Tag Type | Format | Example |
Analog | [Symbol][Decimal Number] | P023 |
Digital | [Symbol][Decimal Number][.][Hexadecimal Number] | P000.F |
Symbol | Address | Description | Access |
P | 0001 - 1760 | Parameter Area The address of each tag can be induced from the parameter number of FC 300 or VLT 2800. For example, to monitor the ‘16-17 Speed [RPM]' of FC 300, the address should be designated with 'P1617’. For more parameters, please refer to the ‘How to Program’ section of the “FC 300 Design Guide”. The value written to this address will be transferred to the FC 300 or VLT 2800 directly. That means parameters of the inverter can be modified by writing the desired value to this address. The new value can be stored to not only RAM, but also to EEPROM of FC 300. For storing a set value to the EEPROM, the C002 point must have a non-zero value. | R/W |
C | 000 | Control Code 1 word-sized control data. Each bit has its own control meaning which is shown in the following ‘Control Code’ table. To control FC 300 or VLT 2800, write a value of the combination of the table. Ensure that the reference (C001) is set as the desired value before issuing this control code. |
...
W | |
001 | Reference This point is a signed word data (-32767 - +32767), and the range of data corresponds to -200% to +200% of reference. For example, the value of 16384 represents 100% of reference. This reference value must be set before the actual control by control code (C000). |
002 | EEPROM Writing If this is non-zero, the value written to the parameter area (Pnnnn) will be saved to the EEPROM as well as RAM of FC 300 or VLT 2800. Otherwise, the set value will be stored only in RAM. Ensure that this point is set as the desired value before parameter writing. |
The addresses above can be used in both analog and digital tags.

Example: Monitors the frequency data
Make an analog tag for frequency data. The address can be induced from parameter 16-13. Designate ‘P1613’ as the address of the new analog tag.
Setup the scale factor of the analog tag if needed. The ‘Conversion index’ of parameter 16-13 is -1. Configure the scaling factor of the tag in the database as 0.1.
...
2. Setup the scale factor of the analog tag. In this example, the value of 0.1 was designated as the scale factor. The ‘Conversion index' of the parameter 07-06 is -4. This index is based on the unit of seconds. For convenience, we can use the unit of milli-secondsmilliseconds, such that the index can be thought of as the value of -1.
...
2. To control the FC 300, write the desired reference value to the ‘Reference’ point, C001, first. Then, write a control value to the ‘Control' point. For example. , write the value of 0x047F for issuing a start command.
...
Shielded twisted pair cable must be used for P-N pair.
Ensure that the shield shielded cable is connected to the COM terminal (61) of FC 300.
