C–2

The block transfer signature is for user information only. The CVIM places
the signature in each block sent to the PLC for identification and does not
care if the PLC changes the signature prior to sending a block back to the
CVIM.

Bits 0–7 designate the block number:

00000000 = Not Valid
00000001 = Block #1
00000010 = Block #2
. . .
11111111 = Block #255

Bits 8–10 designate the toolset:

000 = Not Valid
001 = Toolset #1
010 = Toolset #2
011 to 111 = Reserved

Bits 11 and 12 designate the block type:

00 = Results
01 = Configuration
10 = Templates
11 = Statistics

Bits 13–15 specify the module thumbwheel number:

000 to 111
