A -B 1784-PCIC通信接口
I/O電源通過(guò)M8接頭C和D連接。I/O電源通過(guò)接頭連接C（男）。接頭D（內(nèi)螺紋）用于將I/O電源路由至其他模塊。
除了寄存器說(shuō)明中列出的寄存器外，模塊還有其他更通用的數(shù)據(jù)點(diǎn)。這些寄存器并非特定于模塊，但包含一般信息，如序列號(hào)和硬件版本這些通用數(shù)據(jù)點(diǎn)列在X67系統(tǒng)的“附加信息-通用數(shù)據(jù)點(diǎn)”一節(jié)中用戶手冊(cè)。使用總線控制器上的模塊功能模型254“總線控制器”默認(rèn)情況下僅由不可配置的總線控制器使用。所有其他公交車根據(jù)使用的現(xiàn)場(chǎng)總線，控制器可以使用額外的寄存器和功能。有關(guān)詳細(xì)信息，請(qǐng)參閱X67的“附加信息-在總線控制器上使用I/O模塊”一節(jié)用戶手冊(cè)（3.30或更高版本）。
13.4.2 CAN I/O總線控制器該模塊占用CAN I/O上的2個(gè)數(shù)字邏輯插槽。配置IOMask01通道配置為此寄存器中的輸入/輸出。它還確定輸出監(jiān)控還是過(guò)濾應(yīng)用于通道。輸出被監(jiān)控，但不被過(guò)濾。該寄存器可用于指定所有數(shù)字輸入的濾波器值。
濾波器值可按100μs的步長(zhǎng)配置。但是，按步驟2輸入值是有意義的，因?yàn)檩斎胄盘?hào)每200μs采樣一次。

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.
