2.20.1 Channel x — Application
Options:
The parameter is used to specify the logic function that is allocated to channel x.
Depending on the selection, individual parameters appear for the respective logic function.
– Inactive: The logic functions are not active. No additional parameters available.
– Logic gate: If the function is specified with AND, OR, NAND, NOR, XOR or XNOR, up to ten
input communication objects can be enabled per logic function. The size of the inputs can
be specified either with 1 bit or with 1 byte. At the receipt of a new telegram at the input,
they are switched according to the selected function. The inputs can also be individually
inverted.
Each function has an output object on which results determined from the inputs can be sent.
The size of the output object can, depending on the parameterization, be 1 bit or 1 byte. The
default value that is to be sent at a positive result can be adjusted.
The following parameters are displayed:
Name of channel:
Options:
Naming of the channel. The length of the name is limited to 30 characters.
Logic function:
Options:
The parameter is used to specify the logic gate the communication objects are to be linked
with. See the explanation above.
Number of input objects:
Options:
The parameter is used to set number of input objects that are to be linked in the logic
function. See the explanation above.
Notice
If the parameter is set on "1", the "logic function" parameter is specified on
"NOT".
