Coolmay L02 Series PLC Programming Manual
0: The output change amount (reduction
side) does not overflow;
1: Output change amount (reduction
side) overflow.
*1: When S3+1 action setting (ACT) bit1=1, bit2=1 or bit5=1, S3+20~24 is
occupied.
5.3.4. Notice
When using multiple instructions： It can be executed multiple times at
the same time (the number of loops is not limited), but note that the S3 and D
devices used in the operation cannot be repeated.
Occupied points of parameter S3. : Step response method
1) ACT setting
：
when bit1,bit2,bit5 are all not "0",occupy 25points Soft
Component starting from the Initial Soft Component specified in S3.
2) ACT setting
：
when bit1,bit2,bit5 are all "0",occupy 20points Soft
Component starting from the Initial Soft Component specified in S3.
Step response mode: The self-tuning mode in the PID instruction has only
a step response mode, and the step value is S0+22, which is the upper limit
value.
When specifying the soft component in the power failure holding
area
：
If D. is specified in the program to hold the data register in the power
failure, needs to clear the specified register at the time of program start-up.
Action flag
：
bit 0=0 of S3+1 is positive action, bit0=0 is reverse action;
When heating, is reverse action.
