1756-CN2R/B通信模块
PC轮询模块并将值放入输入寄存器（30XXX）由程序员指定。每次模块通电时，它都会执行诊断测试，重置输入锁存器，并且对于每个信道，向控制器呈现值0000。价值通电后约三秒钟。
然后模块将开始根据吞吐量中的计划转换输入费率部分。开关设置模块后部有一个DIP开关。开关1、2和4不习惯于开关3可以设置为模块复位或模块运行。它必须设置为模块运行位置，以便模块运行。确保设置了开关3将模块插入外壳之前。DIP参考下图开关设置。从盒子中取出模块并检查是否损坏。如果发现损坏，请联系您的销售人员或分销商了解正确的退货程序。
将开关3设置为模块运行位置，将开关4设置为数据范围在将模块插入住房（请参阅第171页的开关设置。）
单元特点下图显示了预安装时的B873-012/B875-012模块。模块中包括一个模拟连接器组件（B873的部件号AS-8533-001-012和B875-012的零件号AS-8533-002）。
连接器套件包括两个安装螺钉、一个导线管和其中一个（B873-012）或两个（B875-012）现场接线连接器。每个连接器有18个嵌入式开槽螺钉端子，可接受各种线规，但16至20建议现场接线使用仪表。接头插入模块，现场接线在左侧。可拆卸的连接器允许在不干扰接线的情况下拆卸和更换模块。
有关端子功能，请参阅端子编号图。
导线管保护模拟输入模块的连接移除紧邻其左侧的模块时损坏或松动。
下表介绍了B873-012导线管的安装&B875-012模块：步骤操作
1关闭壳体电源。
2确定模拟模块将使用哪个插槽。*如果存在风管并且它与连接器集合中提供的不同，则必须将其移除。这通过拆除位于然后拉出导管。
3如果此插槽左侧有一个模块，则必须将其拆除，直到安装管道已完成。
4将导线管插入两个插槽之间，螺钉孔位于左侧。（请参阅安装图。）
5使用包装中提供的两个1/4英寸开槽螺钉，将导线管固定至外壳。
6重新安装模块并完成接线连接。
*风管不能安装在壳体最左侧的槽中。因此，使用不建议使用此插槽的。
The PC polls the module
and places the values into input registers (30XXX) designated by the programmer. Each time the module is powered up, it performs diagnostic tests, resets the input latches, and, for each channel, presents a value of 0000 to the controller. The value is present for approximately three seconds after power up. The module will then start converting the inputs according to the schedule found in the Throughput Rate Section.Switch Settings There is a DIP switch located at the rear of the module. Switches 1, 2 and 4 are not used. Switch 3 can be set to either Module Reset or Module Run. It must be set to the Module Run position for the module to operate. Make sure you set Switch 3 before inserting the module into the housing. Refer to the figure below for DIP switch settings.Remove the module from the box and check for damage. If damage is found, contact your salesman or distributor for correct return procedure. Set Switch three to the Module Run position and Switch four to the data range selected for input - either Standard or Elevated - before inserting the module into the housing. (Refer to Switch Settings, p. 171.) Module Characteristics The following figure shows the B873-012 / B875-012 Module at pre-installation.
Included with the module
is an Analog Connector Set (Part# AS-8533-001 for B873- 012 and Part# AS-8533-002 for B875-012). The Connector Set consists of two mounting screws, a wire duct, and either one (B873-012) or two (B875-012) field wiring connectors. Each connector has eighteen recessed slotted screw terminals and can accept various wire gauges, but 16 to 20 gauge is recommended for the field side wiring.The connector plugs into the module with the field wiring to the left. The removable connector permits module removal and replacement without disturbing the wiring. Refer to diagram for Terminal Numbering, for terminal functions. The wire duct protects the connections to the Analog Input Module from being damaged or loosened when the module to it's immediate left is removed.
The following step table describes the installation of the Wire Duct, for the B873-012 & B875-012 Modules: Step Action 1 Turn off the power to the housing. 2 Determine which slot will be used for the Analog Module.* If there is a duct present and it is different from the one provided in the connector set, then it must be removed.This is accomplished by removing the two screws located on the top and bottom of the housing and then pulling the duct out. 3 If there is a module to the left of this slot, it must be removed until installation of the duct is complete. 4 Insert the wire duct between the two slots with the screw holes to the left. (Refer to the Installation Diagram.) 5 Using the two 1/4 inch slotted screws provided in the package, secure the wire duct to the housing. 6 Re-install the module(s) and complete the wiring connections. * The duct cannot be installed for the left-most slot of the housing. Therefore the use of this slot for the Analog Module is not recommended.
