Mode
This parameter determines which switching values is written into the memory
location of the communication object when the signal state changes at the input.
A rising edge is when the signal state at the input changes from logic “0” to “1”
while a falling edge is a change from logic “1” to “0”.
Options:
Rising ON
Rising OFF
Falling ON
Falling OFF
Rising ON / Falling OFF
Rising OFF / Falling ON
Toggle ON/OFF
Toggle OFF/ON
With this parameter we can program which status we need to send to the bus
(ON/OFF; TOGGLE) when a rising or falling edge is detected in the input signal.
Behaviour:
“Rising On”: A rising edge causes a logic “1” to be transferred to the
communication object. A falling edge does not alter the object value.
“Rising Off”: A rising edge causes a logic “0” to be transferred to the
communication object. A falling edge does not alter the object value.
“Falling On”: A falling edge causes a logic “1” to be transferred to the
communication object. A rising edge does not alter the object value.
“Falling Off”: A falling edge causes a logic “0” to be sent to the communication
object. A rising edge does not alter the object value.
“Rising On, Falling Off”: A rising edge causes a logic “1” to be transferred to the
communication object. A falling edge causes a logic “0” to be sent.
“Rising Off, Falling On”: A rising edge causes a logic “0” to be transferred to the
communication object. A falling edge causes a logic “1” to be sent.
“Toggle ON/OFF”: Each rising edge causes the object value to be inverted. This
means that a logic “1” is sent to the communication object after the first rising
edge. The next one sends a logic “0” and so on. A falling edge does not alter the
object value.
“Toggle OFF/ON”: Each falling edge causes the object value to be inverted.
This means that a logic “1” is transferred to the communication object after the
first falling edge. The next one sends a logic “0” and so on. A rising edge does
not alter the object value.
