产品内容介绍
A -B 1784-PCIC通信接口
I/O电源通过M8接头C和D连接。I/O电源通过接头连接C（男）。接头D（内螺纹）用于将I/O电源路由至其他模块。
除了寄存器说明中列出的寄存器外，模块还有其他更通用的数据点。这些寄存器并非特定于模块，但包含一般信息，如序列号和硬件版本这些通用数据点列在X67系统的“附加信息-通用数据点”一节中用户手册。使用总线控制器上的模块功能模型254“总线控制器”默认情况下仅由不可配置的总线控制器使用。所有其他公交车根据使用的现场总线，控制器可以使用额外的寄存器和功能。有关详细信息，请参阅X67的“附加信息-在总线控制器上使用I/O模块”一节用户手册（3.30或更高版本）。
13.4.2 CAN I/O总线控制器该模块占用CAN I/O上的2个数字逻辑插槽。配置IOMask01通道配置为此寄存器中的输入/输出。它还确定输出监控还是过滤应用于通道。输出被监控，但不被过滤。该寄存器可用于指定所有数字输入的滤波器值。
滤波器值可按100μs的步长配置。但是，按步骤2输入值是有意义的，因为输入信号每200μs采样一次。
事件计数器操作下降沿记录在计数器输入上。
计数器状态以固定偏移量收集到网络周期中，并在同一周期中传输。
闸门测量信息：一次只能使用一个计数器通道进行选通测量。
门输入上升至下降沿的时间使用内部频率进行记录。检查结果用于溢出（0xFFFF）。
测量之间的恢复时间必须大于100µs。测量结果与下降沿一起传输到结果存储器。输入状态以固定偏移量收集到网络周期中，并在同一周期中传输。
已筛选过滤状态以固定偏移量收集到网络周期中，并在同一周期中传输。过滤以200µs的倍数与网络异步发生，网络相关抖动高达50µs。在模块上，输出的输出状态与目标状态进行比较。输出驱动器的控制用于目标状态。
输出状态的更改将重置对该输出的监视。可以读取每个单独通道的状态。监视状态的更改会生成错误消息。
状态数字输出01到状态数字输出16该寄存器用于指示数字输出1至16的状态。
The I/O power supply is connected
via M8 connectors C and D. The I/O power supply is connected via connector C (male). Connector D (female) is used to route the I/O power supply to other modules.In addition to the registers listed in the register description, the module also has other more general data points. These registers are not specific to the module but contain general information such as serial number and hardware version. These general data points are listed in section "Additional information - General data points" of the X67 system user's manual.Using the module on the bus controller Function model 254 "Bus controller" is used by default only by non-configurable bus controllers. All other bus controllers can use additional registers and functions depending on the fieldbus used. For detailed information, see section "Additional information - Using I/O modules on the bus controller" of the X67 user's manual (version 3.30 or later). 13.4.2 CAN I/O bus controller The module occupies 2 digital logical slots on CAN I/O.ConfigIOMask01 Channels are configured as inputs/outputs in this register. It also determines whether output monitoring or filtering is applied to the channels. Outputs are monitored but not filtered.
This register can be used to specify the filter value for all digital inputs. The filter value can be configured in steps of 100 μs. It makes sense to enter values in steps of 2, however, since the input signals are sampled every 200 μs.Event counter operation The falling edges are registered on the counter input. The counter status is collected with a fixed offset to the network cycle and transferred in the same cycle. Gate measurement Information: Only one of the counter channels at a time can be used for gate measurement. The time of rising to falling edges for the gate input is registered using an internal frequency. The result is checked for overflow (0xFFFF). The recovery time between measurements must be >100 µs. The measurement result is transferred with the falling edge to the result memory.On the module, the output states of the outputs are compared to the target states. The control of the output driver is used for the target state. A change in the output state resets monitoring for that output. The status of each individual channel can be read. A change in the monitoring status generates an error message.
