IS220UCSAH1A通用电气模块,GE使用过程上的输入/输出连接到VMEbus P2连接器。MVME712X转换模块连接到MVME187通过电缆和P2适配器板。
串行端口接口CD2401串行控制器芯片（SCC）实现了四个串行端口。串行端口支持标准波特率（110至38.4K波特）。这四个串行端口功能不同，因为P2输入/输出连接器上的引脚数量有限。所有四个串行端口使用EIA-232-D驱动器和接收器，位于MVME187和所有信号线均路由至输入/输出连接器。
IS220UCSAH1A通用电气模块❏ 串行端口1是最小功能异步端口。它使用RXD、CT、TXD和RTS。
❏ 串行端口2和3是全功能异步端口。他们使用RXD、CT、DCD、TXD、RTS和DTR。
❏ 串行端口4是全功能异步或同步端口港口城市它可以以高达64k位/秒的同步比特率运行第二它使用RXD、CT、DCD、TXD、RTS和DTR。它也与同步时钟信号线的接口。串行接口编程注意事项
❏ MVME187板硬件连接来自CD2401连接到接头P2上标记为RTS的引脚。同样，RTS从CD2401连接到P2上的DTR。因此，当编程CD2401，在需要RTS时断言DTR，当您需要DTR时，可以使用RTS。
❏ PCCchip2提供的接口允许16位CD2401出现在连续地址。
❏ 对CD2401的访问必须为8位或16位：32位访问不允许。
❏ CD2401支持对本地内存的DMA操作。
❏ 因为CD2401不支持重试操作为了打破VMEbus锁定条件，CD2401DMA控制器不应编程为访问VMEbus。
❏ 硬件没有将CD2401限制为板载DRAM。有关详细编程，请参阅CD2401数据表
It has changed from the backward situation of manual and semi-automatic labeling to the pattern of automatic high-speed labeling machines occupying the vast market. 2、 Working principle the system uses maintenance control 700L touch screen and lx1s-20mt PLC. The optical fiber amplifier on the machine base irradiates the object, and the signal is fed back. If the signal exists for a certain period of time, the roller on the machine base is pressed down and rotates at the set speed. At this time, the output motor of the feeding side rotates a labeling width, and after the set time, the material slides to the loading box. 3、 Introduction to HMI engineering screen 1. Home page: click start in the lower left corner to jump to the screen option. (1) System parameters: jump to the installment payment interface of the touch screen to encrypt the installment to protect the interests of customers. (2) Operation screen: jump to the operation screen. (3) Parameter setting: stepper motor parameter setting, delay setting, formula upload and download. (4) Manual operation: jump to manual screen (5) monitoring information: plCi / O monitoring (6) recipe record: record recipe upload and download information
(7) Alarm information: record system alarm information
2. Operation screen: the operation screen includes the current working state of the equipment, the output monitoring of PLC, the display of material output, manual / automatic switching and the selection of labeling operation mode.
3. Parameter setting and formula: This screen can set the speed of two stepping motors, as well as the setting of standard stopping delay and pressing delay. After setting these parameters, click Save to pop up the sub screen of formula upload and download. You can save the newly set parameters to the formula or download the parameters originally existing in the formula to the PLC. The parameters in the formula are saved at breakpoints.
