ABB PP846 3BSE042238R1 工控DCS系统备件
您可以在阵列的一端或两端配置空白区域（例如，如果阵列对于应用程序来说太长）；或者在数组中间有一个空白区域（如果中间的某个区域太被忽略）。要激活示教功能，必须打开DIP开关3（并重启控制器电源）以启用远程示教。启用远程教学后，通过打开离散输入IN 1来启动教学过程。中断要忽略的波束/区域，并关闭输入IN 1。IN 1从ON变为OFF时中断的波束确定消隐区域。可以使用DIP开关8或再次执行示教过程来重置空白区域。教学过程中的注意事项：•单个空白区域中不能有任何孔，所有光束必须中断才能定义该区域。•第一消隐区从第一中断射束限定为小于未被阻挡的第一射束。（DIP开关6确定波束计数方向，默认标准波束计数从阵列的电缆端开始。）如果（且仅当）第一个消隐区以波束1开始，也可以创建第二个消隐区域。该区域定义为从下一个中断波束开始（在第一个不中断波束之后）一直到阵列末端，而不管其他波束被中断。•为获得最佳结果，请确认空白区域中的所有光束均已完全阻断。此外，如果正在创建两个空白区域，则确认第一区域包括光束1（基于DIP开关6确定的光束计数方向）。功能描述-I/O模型图5-I/O模型该控制器模型扩展了45MLA控制器的功能，以提供四个附加输出信号和一个示教功能。这些输出可以分配给光阵列上的特定区域或单个光束。引脚列表表12显示了主连接器J2上的引脚分配。表13显示了I/O扩展PCB。状态指示器表14显示了I/O扩展PCB上状态指示器D10…D14的含义。
You can configure blank areas at one or both ends of the array (for example, if the array is too long for the application); Or there is an empty area in the middle of the array (if a certain area in the middle is too ignored). To activate the teach function, you must turn on DIP switch 3 (and restart the controller power) to enable remote teach. After enabling distance learning, start the learning process by opening discrete input IN 1. Interrupt the beam/area to be ignored and turn off input IN 1. When IN 1 changes from ON to OFF, the interrupted beam determines the blanking area. The blank area can be reset using DIP switch 8 or by performing the teach process again. Precautions during teaching: • No holes can be found in a single blank area, and all beams must be interrupted to define the area. • The first blanking area is limited from the first interrupted beam to less than the first unblocked beam. (DIP switch 6 determines the beam counting direction, and the default standard beam counting starts from the cable end of the array.) If (and only if) the first blanking area starts with beam 1, a second blanking area can also be created. This area is defined as starting from the next interrupted beam (after the first uninterrupted beam) to the end of the array, regardless of other beams being interrupted. • For best results, make sure that all beams in the blank area are completely blocked. In addition, if two blank areas are being created, confirm that the first area includes beam 1 (based on the beam counting direction determined by DIP switch 6). Function Description - I/O Model Figure 5-I/O Model This controller model extends the functions of the 45MLA controller to provide four additional output signals and a teaching function. These outputs can be assigned to specific areas on the optical array or to a single beam. Table 12 of the pin list shows the pin assignments on the main connector J2. Table 13 shows the I/O expansion PCB. Table 14 of status indicators shows the meaning of status indicators D10... D14 on the I/O expansion PCB.
