NOTIFICATION/REQUEST MESSAGE BLOCK
8-70
19 Send Source (SENDINP)...................................................................................................C – R
Discrete logical source pointer to trigger source. Source of signal that triggers the
notification/request transaction. Signal is edge triggered.
Trigger
NONE No Send Source; message can only be triggered by an operator write to the
Send Command. If configured as NONE, reading this attribute will
give an invalid attribute error.
LSP A change is this attribute’s value from 0 to 1 triggers the message transaction.
Reading this attribute gives the current value of the LSP.
20 Maximum Response Time (RTIMEINP) .......................................................................... CWR
Timeout value for operator response to message. Reading this field gives the msec-time
value or the current msec-time value of the LSP.
NONE No time out (infinite). If configured as NONE, reading this attribute will give
an invalid attribute error.
msec-time Specifies the maximum time operator has to return requested data. A setting
of 0:0:0.000 implies no time out (infinite response time).
LSP Time limit (in msec-time) retrieved from LSP attribute.
21 Acknowledge Source (ACKINP) ......................................................................................C – R
Remote acknowledgement flag.
NONE No remote acknowledgement. If configured as NONE, reading this attribute
will give an invalid attribute error.
LSP Acknowledged remotely when the LSP attribute changes from NO to YES.
Reading this attribute gives the current value of the LSP.
22 Requested data will be accepted (RCV).......................................................................... CWR
Specifies when writes to the Requested Data field are allowed.
ALWAYS 1 Writing to the Requested Data field is always allowed.
ACTIVE 2 Writing to the Requested Data field is allowed only when Active.
ON_TIME 3 Writing to the Requested Data Field is allowed only while Active and
not Timed Out.
23 Initial Requested Data (Result) (R)................................................................................... CWR
During startup, this is the initial data value. Initial data, if entered, must be same type as data
type selected. The initial value is used if requested data is not received before timeout. This
field can always be written to when in DEBUG state. While in RUN or HOLD, this field can
only be written to as specified in the configuration of the Requested Data Accepted (RCV)
field.
