DEIF GCP3脉冲累加模块
滑动ICT和MPI模块同时沿着模块安装单元的顶部和底部导轨引导电路板的顶部和底边缘。8.推动面板，直到模块的后边缘牢固地固定在背板连接器中。9.转动每个面板的2个锁紧螺钉½圈，将模块锁定到位。当锁紧螺钉上插槽的开口端朝向面板中心时，模块锁定到位。完成第3节中详述的配置和安装步骤后，INFI-NET到计算机接口模块就可以投入运行了。本节提供了INFI-NET到计算机接口模块日常操作的必要信息。通电后，INNIS01网络接口从模块（NIS）微处理器将保持重置模式，直到其相关传输模块（INICT01或INICT03）移除重置模式，并允许固件执行自诊断例程。ICT模块确定NIS模块何时上线。NIS模块在双列直插式开关SW3的位置7和8设置的环路模式下联机，计数器显示由双列直拨式开关SW4的位置4到8设置。使用计数器显示（面板LED）检查NIS模块的操作。如果发生通信错误，主机模块会在模块状态中设置NIS模块通信状态位。使用回路上的监控设备（控制台、计算机等）查看模块状态。
事件计数器
内部计数器维护事件计数，如传输的消息数、重试次数和丢失的消息数。表3-5列出了事件计数器的完整列表。模块面板上的A组和B组LED显示事件计数器的二进制值（LED B-8为最高有效位，LED A-1为最低有效位）。图4-1显示了A组和B组LED的位置。错误计数器错误，如接收错误、具有循环计数错误的消息等，与事件计数器一样，都保存在内部计数器中。有关错误计数器列表，请参阅表3-6。表5-1列出了NIS模块面板LED上出现的错误代码。INICT01 INFI-NET TO COMPUTER TRANSFER MODULE LED和控制器INICT02模块的面板具有以下组件（见图4-2）：•状态LED。•停止按钮。•两个内存状态指示灯。•八个CPU LED。•复位按钮。状态LED是一个双色（红色和绿色）LED，显示ICT模块的工作状态。它有三个州。表4-1列出了状态LED状态的含义。如果状态LED指示存在错误，请参阅第5节了解纠正措施。
Slide the ICT and MPI modules
in while guiding the top and bottom edges of the circuit boards along the top and bottom rails of the module mounting unit. 8. Push on the faceplate until the rear edges of the modules are firmly seated in the backplane connectors. 9. Turn the 2 latching screws of each faceplate ½ turn to lock the module in place. The modules are locked into place when the open end of the slot on the latching screws face the center of the faceplate.After completing the configuration and installation steps detailed in Section 3, the INFI-NET to computer interface modules are ready to be put into operation. This section provides the necessary information for daily operation of the INFI-NET to computer interface modules.On power up, the INNIS01 Network Interface Slave Module (NIS) microprocessor stays in reset mode until its associated transfer module (INICT01 or INICT03) removes the reset mode and allows the firmware to execute self-diagnostic routines. The ICT module determines when the NIS module will go on-line. The NIS module comes on-line in the loop mode set by positions seven and eight of dipswitch SW3, with the counter display set by positions four through eight of dipswitch SW4. Use the counter display (faceplate LEDs) to check the NIS module operation. If communication errors occur, the host module sets the NIS module communication status bits in the module status. View the module status using a monitoring device (console, computer, etc.) on the loop.
Event Counters
Internal counters maintain a count of events such as the number of messages transmitted, retries, and number of messages lost. Table 3-5 has a complete list of event counters. The group A and B LEDs on the module faceplate display a binary value of the event counters (LED B-8 is the most significant bit, LED A-1 is the least significant bit). Figure 4-1 shows the location of the group A and group B LEDs. Error Counters Errors such as receive errors, messages with circulation count errors, etc. are maintained in internal counters just like the event counters. Refer to Table 3-6 for a listing of error counters. Table 5-1 lists the error codes that appear on the NIS module faceplate LEDs. INICT01 INFI-NET TO COMPUTER TRANSFER MODULE LEDs AND CONTROLS The faceplate of the INICT01 module has the following components (see Figure 4-2): • Status LED. • Stop pushbutton. • Two memory status LEDs. • Eight CPU LEDs. • Reset pushbutton.The status LED is a two color (red and green) LED that displays the operating status of the ICT module. It has three states. Table 4-1 lists the meaning of the status LED states. Refer to Section 5 for corrective action if the status LED indicates that an error exists.
