142 System Manual, 07/2009, C79000-G8976-C222-07
Default: Function deactivated
Explanation: Important process data can be given higher priority than the messages
waiting in the send buffer. If you activate the
High priority
function, the
messages of this object are given a higher priority and sent before the
other buffered messages.
Note: In dial-up networks, the
High priority
function does not necessarily
lead to immediate connection establishment. This happens only when the
Conditional spontaneous
function has been deactivated for this object.
Volatile storage mode
output box:
The
Volatile storage mode
output box indicates that a message already stored in the send
buffer of the TIM will be deleted if the subscriber is not available. As long as a subscriber is
disrupted, no new non-retentive messages for this subscriber can be entered in the send
buffer of the TIM. The
volatile storage mode
applies only to the send messages of the
following objects:
-
Cmd01B_S
-
Set01W_S
-
Par12D_S
By deleting command, setpoint and parameter messages, you avoid out-of-date commands,
setpoints all parameters being sent to the destination subscriber when a connection is re-
established following a failure.
The messages of all other send objects are not deleted when there is a connection failure
and further messages can be entered in the send buffer of the TIM during a disruption.
Name: Read cycle
Range of
values:
1:
Normal cycle
2:
Fast cycle
Default: Normal cycle
Explanation: Each data object that sends data must be assigned to one of the two read
cycles. The
normal cycle
is the most suitable selection for most process
data. Data that must be acquired quickly such as alarms and pulse
messages are suitable for assignment to the
fast cycle
.
Command, setpoint and parameter objects for which a 1-out-of-n check is
required, must be assigned to the
fast cycle
. If these objects are acquired
in the normal cycle, they are not included in the 1-out-of-n check.
All send channels of a data object are included in the same read cycle.
The parameters of the read/write cycle themselves are set in the basic
settings of TD7onTIM.
1.10.9 Channel overview and functions of channel parameter assignment
Overview of the channel types
Each data object has a defined number of channels with default parameters. The number of
channels and the data type cannot be changed for an individual data object. Apart from the
