1、本次变频器通讯设定选用的是ABB通讯模块RPBA-011 下图为RPBA-01模块对基本设定以及PZD控制字和状态字的设定细则：2 PZD3 IN 为从变频器发出给PLC的状态字，而PZD3 OUT为从PLC发出的到变频器的状态字，以后依次类推。Par. no.Parameter nameAlternative settingsDefault setting1MODULE TYPE(Read-only)PROFIBS DP2NODE ADDRESSOto 12633BAUD RATE(12000) 12 Mbit/s; (6000) 6 Mbit/s;(3000) 3 Mbit/s; (150

14、AIL-SAFE SPEED为断开后使用FAIL-SAFE里边设定的值运行。 OPERATION MODE须选择VENDOR SPECIFIC。有两种方法可以写入和读取变频器中的参数数据:1. 为写入控制字和读取状态字的方法:通过系统功能块SFC14和SFC15将控制字中从CW以后的10个字写入变频 器中,再在变频器中自定义分配控制字以及状态字的参数号,达到读写的目的. 如下图所示:注:在读取和写入过程中,不必考虑 PKW 的值.因为在此过程中，系统不会读取 PKW中的值.2. 通过PKW来读取变频器中的数据:Example 1： Heading a drive parameter (or a

15、ta set)lb determine the parameter number and subindex for drive parameter reading, multiply the parameter number by one hundred and then convert it to hexadecimal The low byte is the subindex (IND), and the high byte is the parameter number (PNU).
