Default: In general: Function active
With Cmd01B_S, Set01W_S and Par12D_S: Function deactivated and
setting cannot be changed
Explanation: The basic setting for saving messages in the send buffer of the TIM prior to
transmission is the
image memory method set as default in the Image
memory
parameter. As long as a message has not been sent, the process
data in the message waiting to be sent is updated by current process data
if this changes. This setting is practical for most data. It ensures efficient
use of memory for storing messages on the TIM and produces as little
message traffic on the WAN link as possible.
Generally, the default setting for the
Image memory parameter only needs
to be changed to the
Send buffer method with a few objects whose data
changes must be stored individually on the TIM and sent individually to the
partner, for example alarms with a time stamp or analog values with a time
stamp for entry in archives.
With the
Bin04B_S object, selected individual binary inputs can be
transmitted using the send buffer method even if the
Image memory
function is active. You make this setting during the parameter assignment
of the channel type
Binary send in the Send buffer principle mask
parameter.
Name: Conditional spontaneous
Range of
values:
Function active: Transmission is conditional spontaneous
Function deactivated: The transmission is unconditional spontaneous
Default: Function active
Explanation: If the function is activated (transmission is conditional spontaneous), the
message does not trigger connection establishment in dial-up networks.
When using a dedicated lines or Ethernet, this parameter has no
significance since transmission is then always immediate.
If the function is deactivated (transmission is unconditional spontaneous),
the message triggers connection establishment immediately in dial-up
networks.
In the
Bin04B_S object, even if the Conditional spontaneous function is
activated, selected individual binary inputs can trigger
unconditional
spontaneous
transmission. You make this setting during the parameter
assignment of the channel type
Send binary value in the Alarm mask
parameter.
