P5.16 Combination given arithmetic setting
Setting range
LED single digit：Arithmetic 1
0：Addition
1：Subtraction
2：Absolute value（subtraction）
3：Choose Maximum.
4：Choose Minimum.
LED tens digit：Arithmetic 2
0：Addition
1：Subtraction
2：Absolute value（Subtraction）
3：Choose Maximum.
4：Choose Minimum.
5：Operand 3 not be concerned with operation
LED Hundreds & thousands digit: Reserved
Note: only P0.01=7，parameter P5.15、P5.16 are effective.
When P0.01=7, each analog and digital input quantity compounding arithmetic
formula as below:
If P5.16 LED tens digit is set to ―5‖，operand 3 will not participate in the arithmetic，
and only the other two operands 1 and 2 are in operation compounding.
For example first, if P5.15 is set to ―531‖ and P5.16 is set to ―10‖, the operation
compounding is equal to {(digital setting 1+ communication setting)-AI2}
For example second, if P5.15 is set to value ―410‖ and P5.16 is set to ―21‖, the
operation compounding is equal to {(keypad potentiometer – digital setting)-AI1}.
Note:
Algorithm 1: Under any circumstances, the operation process is operating operand 1
and operand 2 according to algorithm 1 to get result 1, then operating result 1 and
operand 3 to get the final result. If operation result 1 of the former two operands is
negative, the negative is defaulted to 0.
Algorithm 2：If the operation result is always negative, moreover algorithm 2 is not
absolute value operation, system will default the result to 0.
