4.5 PHASE 3 - HMI-HMG-BHP / VMF 485LINK RECOGNITION
Having correctly wired the components and set the dip switches SW1, the sequence of operations to be performed to start the recognition of the FCWI unit to the VMF-485LINK
accessory is as follows:
1.
Power the HMI/HMG/BHP unit;
2.
Supply voltage to the expansion VMF-RS485LINK;
3.
Keep the T1 button of the VMF-RS485LINK expansion pressed until the DL6 (red) and DL5 (white) LEDs flash simultaneously;

DL6 - DL5
4.
Wait for the end of the recognition procedure of the HMI/HMG/BHP units' control card. During this phase, the VMF-RS485LINK expansion sends read commands to the
slave device connected to it, if a correct response follows the read command, the recognition procedure of the unit ends, otherwise, it continues with the sending of other
read commands in which the modbus address associated with the node is increased;
5.
If the unit recognition procedure is completed correctly, the expansion will start continuously sending/receiving modbus commands; this normal operating condition will
be indicated by the expansion with the red LED DL6 off and the white LED DL5 flashing.If we are in this condition, the VMF-RS485LINK gateway is ready to be connected,
through the slave port (M3), to a supervision system such as the VMF-E5 and VMF-E6 panel. If the VMF-RS485LINK expansion fails to establish a serial communication
with the unit, it automatically goes into an error condition (failed communication with the slave device) which will be indicated by the flashing of the red DL6 LED only.
