Ethernet Error:801

Ethernet Error:801

Category : 

Answer

This error occurs when there is no physical continuity between the TS/V8 LAN port and a network device (PLC, hub etc.).

 

<Cause>

The most common causes are listed below.
  • The LAN cable is not connected.
  • The LAN cable is broken.
  • A straight cable is connected directly without passing through a switching hub. (Only V8)
  • The LAN cable is connected to the MJ1 or MJ2 port on the TS/V8 series unit.
  • A self-made LAN cable is wired incorrectly.
  • RJ45 connector contacts are defective.
  • The hub is faulty.

 

<Solutions>

  • Check that the LAN cable is connected correctly.
  • Use a cross-cable to directly connect the V8 series unit to a network device.
  • Check that network devices, such as the hub, and the LAN cable are not faulty.

 

Procedure for checking LAN cable continuity

Check the status of the [Connect] lamp on the Ethernet screen accessible from [Main Menu] on the TS/V8 series unit.

For details on the main menu, see below.
