When one of the above errors occurs (except D3, protected mode), the NIM reports
a module error to the INTERBUS network master. The user can then initiate an
appropriate action.
Global Diagnostics (Selector 01h, 02h)
Global diagnostics provide the error/status information for internal island bus
operations. The global diagnostics array is composed of a low byte and a high byte.
When the selector value is 01, global diagnostics low byte information is transmitted
as the status word’s low byte value:
D7 1 = Advantys configuration software is controlling the output data of the island’s
process image
0 = fieldbus master is controlling the output data of the island’s process image
Bit Meaning of Value
Bit Meaning
D0* fatal error—Because of the severity, no further communications are possible on the island bus.
D1* module ID error—A standard CANopen device is using a module ID reserved for the Advantys STB modules.
D2* Auto-addressing (see page 44) has failed.
D3* Mandatory module configuration error.
D4* process image error—Either the process image configuration is inconsistent or it could not be set during auto-
configuration.
D5* auto-configuration error—A module has been detected out of order and the NIM can not complete auto-
configuration.
D6 Island bus management error detected by the NIM.
D7* assignment error—The initialization process in the NIM has detected a module assignment error, possibly the
result of application parameter mismatches.
