Hello Everyone..
I have been working on Fanuc Robodrill alpha T14ia with 16iMA control.
The mahcine is having problem with the I/O link.
There is 1 main I/O board behind the operator panel, then I/O cable JD1A runs to back of machine to basic module of connecting I/O module JD1B.
1. now my first confusion- if we remove JD1B connector from the connecting I/O module, should machine alarm for "Bad I/O Link"
but there is no alarm in machine when we remove this connector.
2. now second thing when we connect the connector back the Inputs/Outputs connected to this connecting I/O module doesn't show in PMC status.
The CONNECTING MODULE consists of Basic Module and Expansion Module as shown in the picture. These modules are connected to the Fanuc wiring PCB.
I have checked the 24V connected to this module, that is Okay.
Please help me out here...
