Entering an external input to a sensor amplifier
Available external inputs: External input 1, External input 2, External input 3, External
input 4
Device assignments: "External Input (5 Words (10 Bytes)) assembly instance
(Instance ID): 65H" (Page 3-16)
This example shows how to enter a External input 2 to the sensor amplifier ID01.
(1)The device value in the OUT area to which an external input request was
assigned is linked via cyclic communication and the external input of the sensor
amplifier is turned on or off.
(2)You can check the input status of the sensor amplifier with the external input
response.
• When at least one of the external input from the communication or the
input signal cable of the sensor amplifier is on, the sensor amplifier
recognizes that the external input is turned on and then executes an
action assigned to the input (OR operation). If, for example, If, for
example, the reset input has been assigned to external input n, and
when either of the external input from the communication or the input
signal cable of the sensor amplifier is turned on, the reset input is
activated.
• To use the external input to switch banks, set "Bank switching method"
of the sensor amplifier settings to "External input".
