How can you read a 32 bit word address 3244 RTH using the IO scanner on the ATV630 drives with optional ethernet card?

Issue:

Needs to read a 32 bit word in the IO scanner maps

Product Line:

ATV630+Etherent option card VW3A3720

Environment:

All

Cause:

Normal words are 16 bit not 32 bit in the IO scanner table

Resolution:

If the ATV630 Drives firmware version is V2.5IE30 or above then you do not have to skip any words in the input scanner table.

If the ATV630 Drives firmware version is older like V2.5IE27 and below he will need skip a line in the scanner table to allow for the 32 bit word or they would need to update he drives firmware to V2.5IE30 which does NOT require you to skip a word in the scanner table.

Examples below:

Drives firmware is V2.5IE30 or higher no need to skip a word in the table.

Scanner input table

3201 ETA 16 bit

8604 RFRD 16 bit

3244 RTH 32 bit

8606 ERRD 16 bit

Drives firmware version is V2.5IE27 and below you need to skip word in the table after the 32 bit word like address 3244

3201 ETA 16 bit

8604 RFRD 16 bit

3244 RTH  16 bit

(note used) so carry over RTH 16 bit next word

8606 ERRD 16 bit

Its bad practice to skip a word in the scanner table to if you need to read a 32 bit word and your ATV630 Drives firmware is V2.5IE27 or older you need to reach out to the Drives Product Support Group to see about updating the drives firmware to V2.5IE30 or above.
