Frequently Asked Questions
如何使用RS-232连接控制器？
DOP接线端应将Controller的RXD (2)接至9 pin D-sub male의 RXD，TXD应接至TXD。GND则需同时连接于(5)和(8)。
PLC的模拟输入和输出范围是多少？
模拟输入（Analog Inputs）地址范围是 %AI1 – %AI8192；模拟输出（Analog Outputs）地址范围是 %AQ1 – %AQ8192。
如果我的控制器型号是Series 90-70 PLC，如何接线？
对于该特定型号（IC697CPU731与 IC697CPU771），导联(9) RD(*)必须与 (11) RD(B)串接，其他型号则RD(*)需与(10) RD(A)串接。
使用RS-422连接时需要注意哪些事项？
通过RS-422连接需根据DOP和Controller的特定系列（如DOP-AS/AE）选择相应的接线图进行，并遵循图示上的引脚分配确保正确连通。
