Hello,

I'm currently at the end of a project for work where I've created a simple stop start program within a LOGO where I can change the speed of a motor using a KTP700.

I can choose the amount of cycles I want the motor to run using increase/decrease buttons and these are stored in a counter which I can retain but the network inputs I use for choosing the speed will always reset to 0 when the machine is powered off. 

I'm trying to find a simple way of storing these speeds within the LOGO so that when they power it back up they can carry on from where they left off.

Thanks in advance

Shaun

Hi ixo65,

Ah right I see, that's the reason why I couldn't find a retentivity setting, no problem then, I'll try doing it this way, thank you for the quick reply.

So I've got an analog amplifier which reads in the network analog input directly from the HMI which is then transferred to a mathematic instruction which does the scaling calculation so it converts to 0-10V correctly.

I've added both to the VM memory as shown in the screenshot but when powering down and back up they figure in them stays at 0.

I'm assuming after powering down and back up the figures in AQ of both B018 and B016 should be reinstated or am I missing something?

Thanks again

I've just figured it out I cant believe I've been struggling with network inputs for so long 

Thank you very much for your help it's very much appreciated.

Shaun
