200PLC能在零下20度工作吗?
西门子还提供S7-200的宽温度范围产品(SIPLUS S7-200):
工作温度范围:-25°C-+70°C
相对湿度:55°C时98%,70°C时45%
其他参数与普通S7-200产品相同

双字寻址由存储区标识符、双字标识符及字节起始地址组合而成。如VD100,其双字寻址方式如图所示。
双字寻址的格式:[区域标识][双字标识符].[字节起始地址]
为使用方便和使数据与存储器单元长度统一,S7-200系列中,一般存储单元都具有位寻址、字节寻址、字寻址及双子寻址4种寻址方式。寻址时,不同的寻址方式情况下,选用同一字节地址作为起始地址时,其所表示的地址空间是不同的。
在S7-200中,一些存储数据专用的存储单元不支持位寻址方式,主要有模拟量输入/输出、累加器、定时器和计数器的当前值存储器等。而累加器不论采用何种寻址方式,都要占用32位,模拟量单元寻址时均以偶数标志。此外,定时器、计数器具有当前值存储器及位存储器,属于同一个器件的存储器采用同一标号寻址。
I/O中断包括外部输入上升/下降沿中断、高速计数器中断和高速脉冲输出中断。S7-200用输入(I0.0、I0.1、I0.2或I0.3)上升/下降沿产生中断。这些输入点用于捕获在发生时必须立即处理的事件。高速计数器中断指对高速计数器运行时产生的事件实时响应,包括当前值等于预设值时产生的中断,计数方向的改变时产生的中断或计数器外部复位产生的中断。脉冲输出中断是指预定数目脉冲输出完成而产生的中断。
(3)时基中断
时基中断包括定时中断和定时器T32/T96中断。定时中断用于支持一个周期性的活动。周期时间从1毫秒至255毫秒,时基是1毫秒。使用定时中断0,必须在SMB34中写入周期时间;使用定时中断1,必须在SMB35中写入周期时间。将中断程序连接在定时中断事件上,若定时中断被允许,则计时开始,每当达到定时时间值,执行中断程序。定时中断可以用来对模拟量输入进行采样或定期执行PID回路。定时器T32/T96中断指允许对定时间间隔产生中断。这类中断只能用时基为1ms的定时器T32/T96构成。当中断被启用后,当前值等于预置值时,在S7-200执行的正常1毫秒定时器更新的过程中,执行连接的中断程序。
