• Reading the State of Function Keys
The HG1P reads the state of the function keys once approximately every 20 ms, and those states are applied to the
HMI Expansion Inputs (LI).
When the state of a function key is ON two consecutive times, the HG1P recognizes that the key has been pressed,
and it processes the read result and makes an ON judgment. When the state of a function key is OFF even once, the
HG1P recognizes that the key has been released, and it processes the read result and makes an OFF judgment.
Time to judge the state of the function key
The time from reading the state of the function key to when the result is judged is as follows.
Time to apply the read results to HMI Expansion Inputs (LI)
For function key inputs, the latest read results when the scan for the screen ends are applied to HMI Expansion
Inputs (LI) at that time.
When there is a change in the state of a function key, the time until the read result is applied to the HMI Expansion
Input (LI) is as follows.
Minimum: 21 ms
Maximum: 39 ms + Scan time (HMI Special Data Register LSD4)

Read result of the
function key
While executing transmitting and receiving processing for user communications, the time required for the
HG1P to process the read result and make an ON judgment will increase because the read processing for
function keys is executed after communication processing has completed.
The longer it takes for display processing and part processing, the longer it will take to apply the read
results to the HMI Expansion Inputs (LI).
CAUTION
• Use the emergency stop switch through the HG1P optional cable as a control signal for external
devices.
• Consider counter-measures for switch bouncing because bouncing will occur during reset
operation.
• Be careful with the switch. If the switch is subjected to excessive shocks or vibrations, it may
deform or become damaged, chattering may occur, operation may fail, or performance may
become degraded.
