APPENDIX A: SNAP ETHERNET-BASED BRAIN MEMORY MAP<br />
Starting Address Length Type Description<br />
FFFF F110 00E0 4 UI Alarm 1: Address of value to check. Use to set multiple alarms on<br />
one point. See brain user’s <strong>guide</strong> for information.<br />
FFFF F110 00E4 4 UI Alarm 1: Is value a float? Yes = 1; no = 0. Yes is default.<br />
FFFF F110 00E8 18 -- Pad for alignment<br />
(Additional alarms follow in order on even 80 hex boundaries.)<br />
FFFF F110 1F80 80 -- Alarm 63<br />
Last valid address for this area: FFFF F110 1FFF<br />
Event Message Configuration—Read/Write<br />
(Does not apply to SNAP Simple I/O) See page 34 in this <strong>guide</strong> <strong>and</strong> the ioManager User’s Guide<br />
for information on configuring messages as reactions to events or alarms. Only the first two<br />
messages are shown. Other messages follow the same pattern.<br />
Starting Address Length Type Description<br />
FFFF F120 0000 4 UI Message 0: Current message state. Messages become active when<br />
Scratch Pad conditions are met. To acknowledge receipt of an active<br />
message, write a 2 to this address. The message will not be sent<br />
again until the conditions are met again.<br />
0 = Inactive, 1 = Active, 2 = Acknowledged<br />
FFFF F120 0004 8 M Message 0: Scratch Pad bits on? (mask)<br />
FFFF F120 000C 8 M Message 0: Scratch Pad bits off? (mask)<br />
FFFF F120 0014 4 B Message 0: Enable streaming (Boolean). Be sure to fill in streaming<br />
configuration section. (See page 118.)<br />
FFFF F120 0018 4 UI Message 0: Stream period in seconds<br />
0 = send once, 604800 = maximum<br />
FFFF F120 001C 4 B Message 0: Enable email (Boolean). Be sure to fill in email<br />
configuration section. (See page 138.)<br />
FFFF F120 0020 4 UI Message 0: Email period in seconds<br />
0 = send once; 604800 = maximum<br />
FFFF F120 0024 4 B Message 0: Enable SNMP trap (Boolean).<br />
0 = disable; non-0 = enable<br />
FFFF F120 0028 4 UI Message 0: SNMP trap period in seconds<br />
0 = send once; 604800 = maximum<br />
FFFF F120 002C 4 UI Message 0: SNMP trap type<br />
FFFF F120 0030 4 UI Message 0: Priority. 0 = high; 1 = low. High is default. Applies only if<br />
you are using SNMP with a modem connection, <strong>and</strong> the brain is<br />
dialing out.<br />
FFFF F120 0034 4 -- Reserved<br />
