execution
● In order to use analog output, set 1 to bit 3 of the operand [S1].
● The output lower limit [S4+1] and the output upper limit [S4+2] should be set according to the
output range of the analog output unit.
● The value of the control interval (Ts): [S4+4] should be modified according to the input
updating interval (normally 0.1 seconds or more) of the analog input unit.
Example) If the value of [S4+4] is K10, Ts is 100 ms.
● Modify other parameters such as the control mode as necessary.
● The manipulated value (MV) stored in the operand [S4] is transferred to the digital value
output area WY that corresponds to the manipulated value of the analog output unit.
● In the manipulated value (MV) of [S4], the output internal calculated value (K0 to K10000) is
converted by the following formula, and stored.
