Description of parameters
Polarity
– defines how the channel logic state will change in response to a change of state of
the communication object selected in the field “Channel virtual input”:
Polarity Object (input) state Channel logic state
0 0
NO
1 1
0 1
NC
1 0
Time of button long pressing
– object monitoring time selected in the “Virtual input” field
(0 - 65535 [seconds]). If value “0” is selected, the long button press event cannot be
generated in the channel.
Channel virtual input
– select the communication block that will be a virtual input of the
channel (changing the object state will generate channel event). You can select the
“Virtual input A…H” object or communication object of function block which has been
activated in the program (e.g. “FB 1…20: switch”).
Only a 1-bit communication object may be a virtual channel input.
4.4.3 Logic channels
You can define 3 logical links in each logic channel. Using the available logic functions AND,
NAND, OR, NOR, XOR, XNOR, you can create a combination function in which the state of
different module channels can be linked (see
Fig. 7
, where: “Input 1…4” = state of physical /
virtual / logical / timer channel). Changing the logical value (0 / 1) resulting from these links
changes the channel logic state. These changes generate the channel events which are
handled by the module. The event generating scheme is shown in
Fig. 8
, where: change in
channel logic state from 0 to 1 = rising edge, from 1 to 0 = falling edge,
