Serial Event Configuration—Read/Write
(Does not apply to SNAP Simple I/O) Use this section to set up events for serial communication
modules attached to the SNAP Ethernet-based brain. For more information on serial
communication modules, see Opto 22 form #1191, the SNAP Serial Communication Module
User’s Guide. For more information on serial events and reactions, see page 32.
Before you configure serial events, configure the serial modules. (See page 111.) In the following
table, only the first two events are shown. Other events follow the same pattern.
Starting Address Length Type Description
FFFF F154 0000 4 M Serial Event 0: Serial port mask. Bits 0-31 correspond to ports 0-31.
On bits represent serial ports to monitor for the event string. Event
occurs if any of the ports receives the event string. NOTE: A null
entry here disables this entry and any higher numbered entries.
FFFF F154 0004 4 -- Reserved
FFFF F154 0008 4 UI Serial Event 0: SNMP trap type (if sending an SNMP trap as a
reaction to the serial event)
FFFF F154 000C 4 UI Serial Event 0: SNMP trap period—how often, in seconds, to send
the trap as a reaction to the serial event
FFFF F154 0010 28 S-ZT Serial Event 0: Pattern string for the event.
Wildcards (* and ?) are allowed.
FFFF F154 0038 28 S-ZT Serial Event 0: Reaction string to be sent with the SNMP trap.
Plug-ins allowed ($!_str_ or $!_port_ and others). See page 34 for
more information.
FFFF F154 0060 8 M Serial Event 0: Scratch Pad bits to turn on
FFFF F154 0068 8 M Serial Event 0: Scratch Pad bits to turn off
FFFF F154 0070 4 UI Serial Event 0: Enable email message (0 = Disable, 1 = Enable)
FFFF F154 0074 4 M Serial Event 1: Serial port mask. Bits 0-31 correspond to ports 0-31.
On bits represent serial ports to monitor for the event string. Event
occurs if any of the ports receives the event string. NOTE: A null
entry here disables this entry and any higher numbered entries.
FFFF F154 0074 4 -- Reserved
FFFF F154 007C 4 UI Serial Event 1: SNMP trap type (if sending an SNMP trap as a
reaction to the serial event)
FFFF F154 0080 4 UI Serial Event 1: SNMP trap period—how often, in seconds, to send
the trap as a reaction to the serial event
FFFF F154 0084 28 S-ZT Serial Event 1: Pattern string for the event.
Wildcards (* and ?) are allowed.
FFFF F154 00AC 28 S-ZT Serial Event 1: Reaction string to be sent with the SNMP trap.
Plug-ins allowed ($!_str_ or $!_port_ and others). See page 34 for
more information.
FFFF F154 00D4 8 M Serial Event 1: Scratch Pad bits to turn on
