(1) The mnemonic, instruction code, operand and program steps of the complement instruction are listed in Table 6-27.
(2) The command ladder diagram is shown in Figure 6-44(a). (3) Instruction description:
1 This instruction is to invert the number of D10 in the target component and then add 1 to it. The result is stored in the same target component, as shown in Figure 6-44(b). Therefore, the pulse execution type should be used when using this instruction; otherwise, when xlo is turned on, a complement operation is performed for each scan cycle.
2 The complement instruction is a variable number operation with absolute absolute values, so the positive numbers are complemented by their opposite numbers, and the negative numbers are complemented to obtain their absolute values.
For example, when D10=7, D10=7 when doing the complement operation. The operation process is shown in Figure 6-45.
Pressure Type Liquid Level Sensor
It is suitable for liquid level measurement of various media in petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage, environmental protection and other systems and industries. The exquisite structure, simple adjustment and flexible installation provide convenience for users to use easily. Standard signal output modes such as 4 ~ 20mA, 0 ~ 5V and 0 ~ 10mA are optional by the user according to needs. Using the principle of hydrostatics to measure liquid level is an important application of pressure sensor. The special cable with ventilation duct in the middle and special sealing technology are adopted, which not only ensures the water tightness of the sensor, but also connects the reference pressure chamber with the ambient pressure, so as to ensure the high precision and high stability of the measurement.
