难道LoadDriver必须在将CP341放置在主站上才能做?
手册上有一段话:
During CPU startup and each time you switch between STOP mode and
RUN mode, the module parameters of the CP are automatically transferred
to the CP as soon as it can be reached via the S7-300 backplane bus.
在et200上进行load driver,是手册里面明确说明可以的。
但奇怪的是,为什么我用315挂et200+cp341搞不通?而且一开始315挂的时候,341的txd都不亮。改成ascii后txd就亮,再改回modbus master后txd也亮了,这期间没有断过电。
