Adjustment on Input Terminal Response Time

Number D1020, D1021
Contents:
1. D1020 can be used for setting up the response time of receiving pulses at X0 ~X7 for ES2
series MPU. Default: 10ms, 0~20ms adjustable.
2. D1021 can be used for setting up the response time of receiving pulses at X10~X17 X7 for
ES2-E V3.48 /28SS2 V3.42 /28SA2 V3.0 /26SE with firmware V2.0 or later versions. Default:
10ms, 0~20ms adjustable.
3. When the power of PLC goes from "OFF" to "ON", the content of D1020 is set to 10
automatically.

4. If the following programs are executed, the response time of X0 ~ X7 will be set to 0ms.
However, the fastest response time of input terminals will be 50μs due to that all terminals are
connected with RC filters..

normally ON contact
5. It is not necessary to adjust response time when using high-speed counters or interrupts
6. Using API 51 REFF instruction has the same effect as modifying D1020 and D1021.

X6 pulse width detecting function

Number M1083,M1084, D1023
Contents:
When M1084 = ON, X6 pulse width detecting function is enabled and the detected pulse width is
stored in D1023 (unit: 0.1ms)
M1083 On：detecting width of negative half cycle (OFFON)
M1083 Off：detecting width of positive half cycle (ONOFF)

Communication Error Code

Number M1025, D1025
Contents:
In the connection between PLC and PC/HMI, M1025 will be ON when PLC receives illegal
communication request during the data transmission process. The error code will be stored in
D1025.
01: illegal instruction code
02: illegal device address.
