SCL"查询每个雇员的情况及其工作部门的情况。"的代码

SCL（Structured Communications Language）是一种用于西门子SIMATIC S7系列PLC（可编程逻辑控制器）的语言，它主要用于编写控制程序。针对你的需求，这是一个基本的SCL代码示例，假设我们有一个包含员工和部门数据的数据结构：

T_EMPLOYEE {
    int emp_id;
    STRING name;
    T_DEPARTMENT department;
}

T_DEPARTMENT {
    int dep_id;
    STRING dep_name;
}

DATA d_employee(0) OF T_EMPLOYEE; // 员工数据块

FUNCTION GET_EMPLOYEE_INFO(emp_id : INT) : T_EMPLOYEE {
    DATA emp = d_employee(emp_id);
    RETURN emp;
}

FUNCTION GET_DEPARTMENT_INFO(dep_id : INT) : T_DEPARTMENT {
    IF (EXISTS(d_employee.dept_id, dep_id)) THEN
        DATA dep = SELECT d_employee WHERE dept_id = dep_id;
        RETURN dep;
    ELSE
        MESSAGE("Department not found", EMERGENCY);
        RETURN NULL;
    END_IF;
}

STARTUP {
    // 查询特定员工信息
    T_EMPLOYEE employee = GET_EMPLOYEE_INFO(1);
    DISPLAY(employee.name + " works in " + GET_DEPARTMENT_INFO(employee.dep_id).dep_name);

    // 可以循环遍历所有员工查询他们的部门信息
    FOR i IN 1 TO COUNT(d_employee) DO
        DISPLAY(GET_EMPLOYEE_INFO(i).name + " works in " + GET_DEPARTMENT_INFO(GET_EMPLOYEE_INFO(i).dept_id).dep_name);
    END_FOR;
}
