Execution - Honeywell SLG 700 Option Manual

Execution

CYCLE TYPE
The parameter CYCLE_TYPE is a bit string that defines the types of cycles that are available for the
resource and supports scheduled and block execution. CYCLE_SEL allows the person doing the
configuration to indicate that one or more of these execution types can be used by the device.
MIN_CYCLE_T is the minimum time to execute a cycle; the minimum cycle time supported is
100ms.
MEMORY
MEMORY_SIZE is the size of the resource for configuration of function blocks; it is represented in
kilobytes. SHED_RCAS and SHED_ROUT set the time limit for loss of communication from a
remote device. These constants are used by each function block and are configurable values.
MAX NOTIFY
The MAX_NOTIFY parameter value is the maximum number of alert reports that this resource can
send without getting a confirmation, and to control alert flooding, adjust the LIM_NOTIFY parameter
to a lower value. If LIM_NOTIFY is set to zero, no alerts are reported. The CONFIRM_TIME
parameter is the time for the resource to wait for confirmation of receipt of a report before trying
again.
FEATURES
The bit strings FEATURES and FEATURE_SEL determine optional behaviour of the resource.
FEATURES bit string defines the available features; it is read only. FEATURE_SEL is used to turn
on an available feature by configuration.
REPORTS
If the Reports option is set in the Features bit strings, the transmitter actively sends alerts to
host/master. If it is not set, the host/master must poll for alerts.
