Data objects: Memory area and triggers of the channels

Enabling the channels of an object
When configuring the send and receive channels, you need to enable the individual channels
so that the transfer of data during operation is enabled for this channel. To allow this, each
channel of an object has the following option:
● Channel active
Select this check box to enable the channel for data transfer.
If you are not sure whether or not you actually require a channel that has already had
parameters assigned or you want to block a channel later (possibly only temporarily), you
can disable it here without losing the parameters that have been entered.
If you do not require certain channels of a data object, ignore them and leave them without a
parameter assignment.
Memory area and triggers
With the two channel classes send channel and receive channel, apart from the object-
specific parameters, the following information is always configured:
● For send channels:
– Input address
– Send trigger
● For receive channels:
– Output address
The parameters are described below.
You can see examples of the parameter assignment dialogs in the two figures below.
200
Here, you specify the source address in the memory area of the CPU for the data to
be sent.
To send data to the communications partner, the TIM accesses this data area of its
local CPU.
Here, you specify whether the data transfer will be triggered and which trigger with
which setting will be used.
Here you specify the destination address in the CPU memory for the received data.
