Available outputs: HI, LO, GO, and alarm output.
This example reads the HI output from the sensor amplifier of ID01.
(1) The output from the sensor amplifier is brought into the remote input device by cyclic transfer.
Available external inputs: External inputs 1 - 4
This example illustrates how to enter a External input 2 into the sensor amplifier of ID01.
(1) The value of the remote output device which is assigned an external input request is linked by cyclic
transfer, so that the external input of the sensor amplifier is turned on or off.
(2) The input status of the sensor amplifier can be checked with the external input response (except for
small-memory mode 1).
• If either the external input via communication or the input signal line
of the sensor amplifier is ON, the amplifier unit recognizes that the
external input is ON and thus executes input operation (ORing).
Example: Suppose that the external input n is set to "reset input." The
reset input is executed if the external input via communication or the
input signal line of the sensor amplifier is ON.
• In cases of using the BANK change function, set the "BANK change
method" parameter of the amplifier unit to "external input change."
