ExternalI/Olink

This fault can be caused by pressing the Reset pushbutton while the link is

 

failure

operating. If that is not the cause, inspect all cabling and examinecarefully

 

 

each link device. Reset the link. If the problem persists, remove devices

 

 

from the link one at a time to isolate the defective unit. This error code may

 

 

also be caused by a hardware problem on the I/O Link Interface Module.

Configuration error

Try to reinitialize the link interface. If the problem persists, contact the GE

 

 

Fanuc PLC service hotline (phone number: 1±800±978±5747).

Link interface is not

Check that the I/O Link Interface Module is installed in the rack and slot

 

responding

location specified in the %P configuration data. Also determine if the

 

 

module is inserted completely in the backplane, and the VME bus is

 

 

operating to other modules in that rack. Make sure that the Logicmaster

 

 

configuration has been correctly completed for the module as described in

 

 

chapter 4. Reset the module by cycling power on the rack. If the problem

 

 

persists, replace the link module.

 

 

 

6

Link Reset

This code indicates that a reset has occurred, or that the application program

 

 

has reset the link by writing a 1 to control bit 13. The fault bit (status bit 12)

 

 

is not set. The I/O Link Module automatically resets control bit 13 to 0 to

 

 

acknowledge that it has received the command.

 

 

 

9

Invalid Number of

This code means that the number of I/O Link Interface Modules is not in the
