你好
Hi,
有人知道在我的第7步程序中,我如何在控制泵时在数字模式和控制泵时的模拟模式之间切换吗。例如,在我的程序中,我在数字模式下执行xyz,但我希望能够在没有数字模式干扰的情况下切换到模拟模式。
Does anyone know how in my step 7 program I am able to switch between digital mode when controlling a pump and analogue mode when controlling a pump. For example in my program I am doing xyz when in digital mode but I want to be able to switch to analogue mode without an interference from the digital mode.

Hi
请提供更多信息。
Please give more information.
泵是由逆变器控制还是通过接触器打开/关闭?
Is pump controlled by inverter or it is on/off via contactor?
你到底想实现什么?
What exactly You want to achieve?
i、 e.需求0…x的脉冲控制和需求x…max的变速控制?
i.e. pulse control for demand 0...x and variable speed control for demand x...max?

Hi,
泵是开/关或通过模拟控制0-10V可变,我可以做到这一点,我想知道当切换到另一个时,是否有可能使它们不相互干扰。
the pump is either on/off or variable 0-10V by analogue control, Which I can do I want to know if its possible to make these not interfere with each other when switched to the other.
嗨,
Hi,
我不确定你想做什么。
I am not sure what do you want to do.
我假设你有一个VFD,你想在手动模式(开/关和用户定义的速度SP)或自动模式(开、关和外部PID给出速度SP)下操作它。您必须使用FB管理电机模式,并向VFD发出启动-停止电报。速度参考可单独发送至VFD。多种多样。您使用什么硬件?
I assume you have a VFD and you want to operate it in either Manual mode(On/Off & user defined speed SP) or Automatic mode(On/Off & external PID give speed SP). You have to use an FB manage the Motor modes, and gives start stop telegram to the VFD. The speed reference can be sent separately to the VFD. Many variation. What HW do you use?
这里有很多应用程序示例。你需要什么帮助,快来问!
Plenty application example up here. Any help you need come and ask!
你好
Hi
是的,这正是我想做的,我已经为开/关和模拟控制编写了一个程序,但我正在努力将它们放入FB,然后两个在我的OB1中调用它们
Yes that is pretty much what I want to do, I have written a program for both ON/OFF and analogue control but I am struggling to put them into FB and then two call them in my OB1.
当做

它不是VFD,只是两种不同的模式:开-关或连续PID
Its not VFD, just two different modes either ON OFF or contineous PID
