10. Troubleshooting

Slide 21 of 23

Technique of Troubleshooting

• Make sure Network option is ON• For MX150/250 -- can be set in user menu• For MX200 – Must be set in factory mode


10. Troubleshooting

Slide 22 of 23

Technique of Troubleshooting

• Make sure cable is less than 3000ftOtherwise add repeater.

• Perform local communication1 master – to – 1 slave device

• Perform global communicationa. Configuration via 50P-1111b. EnerVista:

b.1 – Setupb.2 – Plug-n-play

• Have spare (good) devices(I.e. Converter, Modbus card)


11. Q&A

Slide 23 of 23

• Terminating Resistor – For noise cancellation

• Noise issue due to EMI effect (I.e. Motor drive)

• Typically chassis ground one (master) end of shield but not both.(use Belden shielded pair)

• Network length –• up to 3000 feet• More than 3000 feet will need a repeater

• Need to understand the register map

• Modbus’ connection is polarity specific

• LonWork’s connection is non-polarity specific

• Conversion of Half-to-full duplex or vice versa: Use 50W-1225
