Communicating with the GT2 Series
Entering an external input to a sensor amplifier
Available external inputs: PRESET, TIMING, RESET, error clear
Device assignments: "External Input (5 Words (10 Bytes)) assembly instance
(Instance ID): 65H" (Page 3-15)
This example shows how to enter a TIMING input 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.
• To use the TIMING input, set "Simultaneous Input Setting" of the sensor
amplifier to "Individual Input".
• To use the TIMING input, set the "Timing Type" of the sensor amplifier to
"External Timing Input".
After the external input is executed, the button operation of the sensor
amplifiers is locked for about 10 seconds. "COM-Lock ( )" is
displayed for about 2 seconds during switching to the locked state or
when an attempt is made to operate a locked button. When button
operation is unlocked, "COM-Unlock ( )" is displayed for about 2
seconds. However, the initialization screen appears when an initialization
reset is executed. If an external input is repeatedly executed when the
initialization screen is being displayed, the initialization screen is retained.
