Function Group
Input points time delay
Number D1020~D1021
Contents:
1. ELC-PB/PC/PA/PH, ELCM-PH/PA controllers X0~X7: 10ms (factory default), 0~20ms
adjustable. Refer to the usage of special registers D1020.
2. ELC-PH controllers X10, X11: 0 times (factory default), 0~20 times adjustable (Scan cycle is
the base). Refer to the usage of special registers D1021.
3. D1020 can be used for setting up the response time of receiving pulses at X0 ~X7 for ELC-
PV controllers. (Setup range: 0 ~ 60; Unit: ms)
4. D1021 can be used for setting up the response time of receiving pulses at X10 ~X17 for ELC-
PV controllers. (Setup range: 0 ~ 60; Unit: ms)
5. When power to the ELC goes from OFF
→
ON, the content of D1020 and D1021 will become
to 10 (default) automatically.

6. When setting the X0~X7 response time to 0ms to execute following program, the faster
response time input terminal will be 50 μ s due to input terminal connection to an RC filter
circuit in series.

7. It is not necessary to adjust response time when using high-speed counter or an interrupt in
the program.
8. It is the same to use instruction REFF or change the content of D1020 and D1021.

ELC-PB/PA/PC/PH, ELCB-PB X0 input point can detect pulse width
Number
M1084
、
D1023
Contents:
X0 input point of ELC-PB/PA/PC/PH V1.4, ELCB-PB controllers can detect pulse width. Whenever
X0 turns from ON to OFF, the value will be updated once and stored in D1023 (unit: 0.1ms). The
minimum detectable width is 0.1ms and maximum 10,000ms.
