Frequently Asked Questions
如何用 RS-232 连接控制器？
使用9 pin D-SUB连接；TXD从DOP的(2)/(7)接到Controller接线的TXD，RXD从(7)/(2)到RXD，GND也需连接。
RS-422 通讯模块默认设定值是什么？
若连接CNET通讯模块，通讯设定量应改为：38400, 8, None, 1。(适用于 RS-422 / RS-485)。
输入图像数据的地址范围是多少？
位数据为 %IXb.s.n (%IX0.0.0 - %IX1.7.63)；字数据为 %IWb.s.n (%IW0.0.0 - %IW1.7.3)。
内部内存的存储范围和类型如何确定？
字（Word）在 %MWn/%MDn，地址范围分别为 %MW0 – %MW4095 和 %MD0 – %MD2047。
