Troubleshooting with the DeviceNet Unit Indicators Section 9-1

Verification Error: Unsupported Connection

Remote I/O Communications Error

DeviceNet Unit Response

Records the error in the error log.

The master will periodically attempt to reconnect with the slave with the verifi- cation error.

Flags Allocated for C200H DeviceNet Master Unit (CIO n+24)

Bit 14 (Error Flag) and bit 07 (Comparison Error Flag) will be ON.

CIO Area Flags Allocated to DeviceNet Unit

Bit 00 of n+12 (Comparison Error Flag) and bits 00 and 01 of n+10 (Unit Error Flag and Master Function Error Flag) will be ON.

Correction

Inspect the slave and then create the scan list again.

7-segment	MS indicator	NS indicator	Error log (Hex)
d6	---	Red (flashing)	0344

Likely Cause

The device does not support the I/O service specified in the scan list. (Occurs with the scan list enabled.)

DeviceNet Unit Response

Flags Allocated for C200H DeviceNet Master Unit (CIO n+24)

Bit 14 (Error Flag) and bit 07 (Comparison Error Flag) will be ON.

CIO Area Flags Allocated to DeviceNet Unit

Bit 00 of n+12 (Comparison Error Flag) and bits 00 and 01 of n+10 (Unit Error Flag and Master Function Error Flag) will be ON.

Correction

Inspect the slave and then create the scan list again.

7-segment	MS indicator	NS indicator	Error log (Hex)
d9	---	Red (flashing)	0345

Likely Cause

A timeout occurred during remote I/O communications using the master func- tion. (The response from the slave timed out 6 consecutive times.)

DeviceNet Unit Response

Records the error in the error log.

The master will periodically attempt to reconnect with the slave with the error, but remote I/O communications will stop if the master is set to stop communi- cations.

Flags Allocated for C200H DeviceNet Master Unit (CIO n+24)

Bit 14 (Error Flag) and bit 06 (Communications Error Flag) will be ON.

CIO Area Flags Allocated to DeviceNet Unit

Bit 02 of n+12 (Remote I/O Communications Error Flag) and bits 00 and 01 of n+10 (Unit Error Flag and Master Function Error Flag) will be ON.
