Interlock protection: ladder diagram is very similar to electrical interlocking logic diagram. After i/o address is determined, it is easy to operate and readable to write ladder diagram for chain protection. In order to protect equipment and production safety, 21 interlocking circuits are compiled in this system（ Ladder diagram)
2.4.3.i/o module setting and correction:
After the ladder diagram is written, the necessary setting and correction of i/o module must be carried out to make PLC work normally; The analog module shall set the type of input signal corresponding to the field equipment and the pretreatment method for the input signal, and also correct the zero point and range; PID module not only sets the type of input signal and the pretreatment method of input signal, but also sets the contents of the storage area of PID module and its modification mode, the modification mode of the setting value of the regulating circuit, the control function of PID and the control mode. 2.5. configuration of operation station software:
The configuration of the operation station adopts the system software FIX32 of integration as the technical platform: its main contents include: system configuration, database establishment, flow chart drawing, historical trend and report, etc.
The system configuration in this system is actually to install fix system on PC, its main content is to define the installation directory of fix system, install interface device driver to configure SCADA system, configure alarm system, configure network, etc. Fix provides a large i/o interface device driver library. The system is configured with PLC with Omron as the control station. Therefore, it is necessary to choose the PLC which installs i/o driver omr.drv and OMRON to communicate.
Database establishment: database is the basis of SCADA system work, it is composed of a series of data points, each data point is actually a function block, fix provides various functional blocks to meet different needs, these functional blocks or read and write data to interface equipment, or to perform operation and alarm processing for data. To establish a data point in the database is to define a function block, which includes: function block type, data point tag, comment, zero point, range, interface equipment, i/o address, data format, alarm upper and lower limit, etc. For example, add an AI module to the database and define it in its properties dialog box“ The tag number is "LT-101", "description" is "buffer spherical tank f0101a liquid level", "interface equipment" is "OMR", "i/o address" is "d:dm:232", "data format" is "12al", "zero point" is "0", "range"<
