Trouble ShootingA2Trouble ShootingThis section provides some help on solving common problems that may occur. For details of the MODBUSOrganisation’s web site (www.modbus.org). <strong>Trend</strong> is not responsible for the content of external web sites.For serial variants of the driver the LEDs on the IQ3/XNC’s serial board can be used to check that you are connectedto the right serial port. The LEDs should be illuminated as below if not there is a fault with the connection:TX ON transmitting, and OFF when it is receiving. It flashes during communications.RX ON when receiving, and OFF when it is transmitting. It flashes during communications.RTS/TXEN For RS232 ON when the interface is ready to receive and handshaking is selected.For RS485 4 ON when the interface is enabled to receive.For RS485 2 ON when the interface is in receive mode and OFF when it is in transmit mode.CTS/RXEN For RS232 ON when the connected equipment is ready to receive and handshaking is selected.For RS485 4 wire ON when the connected equipment is enabled to receive.For RS485 2 wire OFFIf the LEDs are as expected then it is necessary to analyse the frames of the messages being sent and received. Thisrequires knowledge of MODBUS protocol.To view the message frames:1. Run SET an display the IQ3/XNC in the System View .2. Display the IQ3/XNC’s web pages.3. Click Modules.4. Click XNC Interfaces, and click t1. A new web browser is displayed.5. In the Alarm Reporting LAN box enter the LAN of the CNC SET is using to connect to the network.6. In the Alarm Reporting OS box enter the network address of the CNC SET is using to connect to the network.7. Click .8. In the Debug Active box select ‘ON’, and click .9. Go to SET’s System View and right click the site containing the IQ3/XNC and select Comms window fromthe displayed menu. The Communications dialogue box is displayed. This will show any communicationsbetween the XNC and the MODBUS devices.IQ3/XNC MODBUS Driver Manual TE201101 Issue 2, 12-Apr-201143
