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 check box:
●
Channel active
Select this option to activate the channel for data transfer.
If certain channels of a data object are not required, they can be ignored. 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.
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
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.
–
Send trigger
Here, you specify whether the data transfer will be triggered and which trigger with
which setting will be used.
●
For receive channels:
–
Output address
Here you specify the destination address in the CPU memory for the received data.
The parameters are described below.
You can see examples of the parameter assignment dialogs in the two figures below.
