Communication Troubleshooting

Generally

1.Check the following:

•There is power at the unit

•The LCD is showing the relevant data

•The device can be programmed using the hand programmer

2.Check the wiring pin outs and verify that the connection is correct.

3.Verify that values in the set-up parameters (P770 to P779) match the settings in the computer used to communicate with the unit.

4.Check that the port on the computer is correct. Sometimes trying a different Modbus driver will solve the problem. An easy stand-alone driver called ModScan32 is available from Win-Tech at www.win-tech.com. This driver is helpful for testing communications.

Specifically

1.The MultiRanger is set to communicate via a modem but no communication is returning to the master.

•Check that the parameters are set up correctly and that the correct port is configured

•Verify the wiring diagram. Note that there is a difference between wiring directly to a computer and wiring to a modem.

•Verify that the modem is set up correctly. Siemens Milltronics has a series of Application Guides that may help. Please contact your local Siemens Milltronics representative for more information on Application Guides.

2.A MultiRanger parameter is set via remote communications, but the parameter remains unchanged.

•Some parameters can only be changed when the device is not scanning. Try putting the device in program mode, using the operating mode function.

•Try setting the parameter from the keypad. If it can not be set using the keypad, check the lock parameter and set it to 1954.
