IP-Quadrature是艾默生过程控制有限公司的一种计数器。

IP-Quadrature是用LS7166集成电路实现的，每个通道有一个IC；每个IP-Quadrature LS7166个IC。LS7166集成电路包含以下内部组件：在Match上也可能产生中断。这个预设/比较寄存器可以编程为任何值，包括或FFFFFF或000000（至模拟“溢出”时的中断）。下溢和上溢都有专用的触发器，可以通过读取计数器的控制寄存器来读取。

IP-Quadrature提供了高密度、高性价比的灵活实现解码器通道。通道也可以用作通用计数器。四个独立通道提供24位分辨率，可编程模式，可编程极性，中断能力，差分或单端（RS-422或TTL/CMOS）输入，实时读取能力，和计数频率为0~10MHz2。

IP-Quadrature提供一个RS-422级缓冲的8MHz时钟输出。这个连续的时钟可以由用户连接到任何通道的X或Y计数输入。然后，用户可以使用Z控制输入作为门，有效地使该通道成为具有分辨率的门控24位定时器当正确编程时为125纳秒。

IP-QUADRATURE每个计数器通道的X和Y输入的极性都是可无识别结果inxLCA中实现了可编程极性。有一个默认的极性，称为两种输入的“标准”。标准极性由每个计数器的通道配置寄存器。下面的时序图显示了标准极性如果通道配置寄存器中的极性位设置为“1”，则“反转极性”。除非另有说明。标准极性信号由RS-422输入模式下的“正”电平、脉冲或边沿组成。(这个意味着+输入具有比-输入更高、更正的电压。）单端逻辑电平输入模式，标准极性由“负”电平、脉冲或边缘组成。(这意味着输入在逻辑0处，大约0.7伏或更小。）这种极性的定义是惯例。TTL信号在历史上一直是“低电平有效”传感器和光耦合器处于“低激活状态”RS-422信号的极性反转可以通过反转+和-输入信号来实现，或者通过将通道配置寄存器中的极性位编程为“1”。这些不是具有完全相同的效果，因为浮动输入将具有不同的效果。一般来说标准极性，浮动〈(断开连接）输入进入最良性的状态。这通常不是浮动输入的情况，其中极性已被编程为“反向”。

IP-Quadrature is a counter of Emerson Process Control, Inc.

IP-Quadrature is implemented using LS7166 integrated circuits with one IC per channel; Each IP-Quadrature LS7166 ics. The LS7166 integrated circuit contains the following internal components: Interrupts may also be generated on Match. This default/compare register can be programmed to any value, including

Or FFFFFF or 000000 (interruption to simulation "overflow"). Both underflows and overflows have dedicated triggers that can be read by reading the counter's control register.

IP-Quadrature provides a high density, cost-effective flexible implementation decoder channel. Channels can also be used as universal counters. Four independent channels provide 24-bit resolution, programmable mode, programmable polarity, interrupt capability, differential or single-ended (RS-422 or TTL/CMOS) input, real-time read capability, and count frequencies from 0 to 10MHz2.

IP-QUADRATUR GE module

IP-Quadrature provides an RS-422-level buffered 8MHz clock output. This continuous clock can be connected by the user to any channel of X or Y count input. The user can then use the Z control input as a gate, effectively making the channel a gated 24-bit timer with resolution to 125 nanoseconds when properly programmed.

IP-QUADRATURE The polarity of the X and Y inputs for each counter channel is unrecognizable as a result programmable polarity is implemented in inxLCA. There is a default polarity, called the "standard" for both inputs. The standard polarity is configured by the channel register of each counter. The following timing diagram shows standard polarity. If the polarity bit in the channel configuration register is set to "1", the "polarity is reversed". Unless otherwise stated. The standard polarity signal consists of a "positive" level, pulse, or edge in the RS-422 input mode. (This means that the + input has a higher, corrected voltage than the - input.) Single-ended logic level input mode, where standard polarity consists of "negative" levels, pulses, or edges. (This means that the input is at logical 0, about 0.7 volts or less.) This polarity is defined by convention. TTL signals have historically been "low active" sensors and optical couplers in a "low active state" Polarity reversal of the RS-422 signal can be achieved by inverting the + and - input signals, or by programming the polarity bits in the channel configuration register to "1". These do not have exactly the same effect, because floating inputs will have different effects. In general, the standard polarity, floating < (disconnected) input enters the most benign state. This is not usually the case with floating inputs, where the polarity has been programmed to "reverse".
