APPENDIX A: SNAP ETHERNET-BASED BRAIN MEMORY MAP Digital Point Write—Read/Write Although this area is read/write, you would normally write to it. See “Digital Point Data” on page 43 for help in formatting data. For information on using counters, see page 21. NOTE: To turn points on and off, you can also write to the point state address in the Digital Point Read area (page 121). 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 F090 0000 4 B Point 0: Turn on (Boolean) 0 = no effect; non-0 = turn on point FFFF F090 0004 4 B Point 0: Turn off (Boolean) 0 = no effect; non-0 = turn off point FFFF F090 0008 4 B Point 0: Activate counter (Boolean) 0 = no effect; non-0 = activate FFFF F090 000C 4 B Point 0: Deactivate counter (Boolean) 0 = no effect; non-0 = deactivate FFFF F090 0040 4 B Point 1: Turn on (Boolean) 0 = no effect; non-0 = turn on point FFFF F090 0044 4 B Point 1: Turn off (Boolean) 0 = no effect; non-0 = turn off point FFFF F090 0048 4 B Point 1: Activate counter (Boolean) 0 = no effect; non-0 = activate FFFF F090 004C 4 B Point 1: Deactivate counter (Boolean) 0 = no effect; non-0 = deactivate FFFF F090 0080 4 B Point 2: Turn on (Boolean) 0 = no effect; non-0 = turn on point FFFF F090 0084 4 B Point 2: Turn off (Boolean) 0 = no effect; non-0 = turn off point FFFF F090 0088 4 B Point 2: Activate counter (Boolean) 0 = no effect; non-0 = activate FFFF F090 008C 4 B Point 2: Deactivate counter (Boolean) 0 = no effect; non-0 = deactivate (Additional points follow in order on even 40 hex boundaries.) FFFF F090 0FC0 4 B Point 63: Turn on (Boolean) 0 = no effect; non-0 = turn on point Last valid address for this area: FFFF F090 0FCF 122 SNAP Ethernet-Based I/O Units Protocols and Programming Guide
Analog Point Read—Read Only See “IEEE Float Data” on page 43 for help in interpreting 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 F0A0 0000 4 F Point 0: Analog input/output data (float—Engineering Units) FFFF F0A0 0004 4 F Point 0: Analog input/output data (float—counts) FFFF F0A0 0008 4 F Point 0: Analog Min Value (float—Engineering Units) FFFF F0A0 000C 4 F Point 0: Analog Max Value (float—Engineering Units) FFFF F0A0 0040 4 F Point 1: Analog input/output data (float—Engineering Units) FFFF F0A0 0044 4 F Point 1: Analog input/output data (float—counts) FFFF F0A0 0048 4 F Point 1: Analog Min Value (float—Engineering Units) FFFF F0A0 004C 4 F Point 1: Analog Max Value (float—Engineering Units) FFFF F0A0 0080 4 F Point 2: Analog input/output data (float—Engineering Units) FFFF F0A0 0084 4 F Point 2: Analog input/output data (float—counts) FFFF F0A0 0088 4 F Point 2: Analog Min Value (float—Engineering Units) FFFF F0A0 008C 4 F Point 2: Analog Max Value (float—Engineering Units) (Additional points follow in order on even 40 hex boundaries.) FFFF F0A0 0FC0 4 F Point 63: Analog input/output data (float—Engineering Units) Last valid address for this area: FFFF F0A0 0FCF SNAP Ethernet-Based I/O Units Protocols and Programming Guide 123
