APPENDIX A: SNAP ETHERNET-BASED BRAIN MEMORY MAP
Analog Point Write—Read/Write
Although this area is read/write, you would normally write to it. See “IEEE Float Data” on
page 43 for help in formatting data.
Only the first three points are shown in the table. Each successive point starts on an even 40 hex
boundary and follows the same pattern.
Starting Address Length Type Description
FFFF F0B0 0000 4 F Point 0: Output analog data (float—Engineering Units)
FFFF F0B0 0004 4 F Point 0: Output analog data (float—counts)
FFFF F0B0 000C 4 F Point 0: TPO period (float—units of time in seconds. Valid range:
0.25 to 64.0 seconds, in 0.25 steps.)
FFFF F0B0 0040 4 F Point 1: Output analog data (float—Engineering Units)
FFFF F0B0 0044 4 F Point 1: Output analog data (float—counts)
FFFF F0B0 004C 4 F Point 1: TPO period (float—units of time in seconds. Valid range:
0.25 to 64.0 seconds, in 0.25 steps.)
FFFF F0B0 0080 4 F Point 2: Output analog data (float—Engineering Units)
FFFF F0B0 0084 4 F Point 2: Output analog data (float—counts)
FFFF F0B0 008C 4 F Point 2: TPO period (float—units of time in seconds. Valid range:
0.25 to 64.0 seconds, in 0.25 steps.)
(Additional points follow in order on even 40 hex boundaries.)
FFFF F0B0 0FC0 4 F Point 63: Output analog data (float—Engineering Units)
Last valid address for this area: FFFF F0B0 0FCF
