Distribution of data exchange address between operation station and control station: the data communication between operation station and control station is completed by reading and writing internal register of PLC. In order to realize real-time communication between operation station and control station, enough internal register address must be configured for PLC to store these data; For example, dm0232 is defined as the internal register of exchanging LT-101 data between the operating station and the control station, and the PLC stores the liquid level signal collected from LT-101 in dmo232 after preprocessing, while the operation station reads the data of LT-101 to the dm0232 of PLC to establish its own database; In this system, 184 points of such addresses are defined.
The allocation of intermediate address: during the operation of PLC, a large number of intermediate registers are needed to store the temporary data in the operation process. In order to improve the readability of the application, it is necessary to define and comment these registers.
2.4.2. prepare ladder diagram for control strategy
Automatic adjustment: three pid03 modules are selected to form 6 regulating circuits to complete the automatic control of the production process. In order to facilitate the management of the control process by the operator in the operation station, SW2 of pid03 should be set to on and corresponding ladder diagram shall be written to realize the data exchange between PLC and pid03. For example, the adjustment return Pic11 is completed by the second circuit of pid03 with unit number 5, When a program shown in Figure 2 is executed, the data in the address dm0060 in the PLC is defined as the given value of the regulating circuit Pic11（ Complete ladder)
Three out of two voting: in order to ensure safe production, the pressure of atmospheric tank must be controlled within the specified range. When the pressure rises (decreases) to a certain range, the corresponding equipment must be started (stopped); Therefore, three pressure gauges are used to measure the pressure in the field. The PLC compares the three pressures. Only when two of the three pieces have the conditions at the same time, the interlock can act; When writing ladder, the control strategy can be realized by comparing instructions, adding with, or, non logical instructions（ Ladder diagram)
