司钻台控制程序工作流程大致可描述为：当控制程序启动，初始化端口对PLC的端口Port1进行初始化，以实现与LED显示控制板的数据通信，然后读入开关量并存入到发送缓冲区，然后读取A/D结果并存入到发送缓冲区，调用泥浆密度、粘度、失水调节子程序，再调用XMT子程序，发送数据到LED显示控制板，如接通左猫，则输出800到D/A，让左猫显示正常工作压力值；否则输出0到D/A，然后判断右猫是否接通，若接通则输出800到D/A，让右猫显示正常工作压力值；否则输出0到D/A，然后调用按钮指示灯控制子程序，而后调指重表控制子程序，根据指重表的悬重值来输出步进脉冲，控制步进电机转动，以使悬重指针指到对应值，最后返回端口初始化，如此循环。
泥浆密度调节子程序工作流程大致可叙述为：子程序开始运行，读入开关量，如果选择增大按钮被按下，则密度值增加0.01，否则执行减小按钮是否被按下操作，若是则密度值减小0.01，然后返回子程序开始状态，如不是也返回子程序开始状态，如此循环。 泥浆粘度和失水调节子程序流程与泥浆密度调节子程序流程类似。
指重表控制子程序，根据指重表的悬重值来输出步进脉冲，控制步进电机转动，以使悬重指针指到对应值，其工作流程大致可描述为：子程序开始运行，从接收缓冲区读取指重表悬重值，如果悬重值为0并且悬重指针本身也处在零点时，直接返回；如果悬重值为0而悬重指针不在零点时就控制步进电机逆时针转动直至悬重指针到零点，当悬重值不为0时，首先判断是否发生了变化，如果没有变化则直接返回，如果有变化时，再判断悬重值是变大还是变小，如变大的话则置步进电机方向控制标志为1（顺时针转），如变小则置步进电机方向控制标志为0（逆时针转），然后计算悬重变化差值，输出1个步进脉冲悬重差值减1直到0后返回。
司钻台侧面控制面板主控程序工作流程大致为：程序开始，初始化就绪指示灯，读入开关量并存入到发送缓冲区，读入A/D结果并存入到发送缓冲区，判断内防喷器是否关闭，若是内防喷器指示灯亮，然后判断液压泵是否运行，如是则液压泵运行指示灯亮，如不是则灭，再判断回转头是否锁紧若是则回转头锁紧指示灯亮，否则灭，然后调转速设定子程序和扭矩设定子程序，若转速设定标志为0（该标志值是在转速设定子程序中被设定）则从接收缓冲区读转速数据输出到D/A，若不为0则转速表就显示从主机PC发送过来的转速值，再判断扭矩设定标志是否为0，若为0则从接收缓冲区读扭矩数据输出到D/A，然后返回，否则直接返回。
钻井扭矩设定程序，工作流程大致为：子程序启动，读取A/D结果，判断设定旋钮是否在被调节，当有变化时表示操作人员正在设定钻井扭矩上限值，此时，仪表就实时显示当前调节值，在3秒内没有再发生变化的情况下，就视为已设定，之后该仪表将显示来自主机PC发送过来的钻井扭矩值，最后返回子程序。 转速设定程序流程图与钻井扭矩设定程序流程图类似。
