Part of a plant SCADA upgrade, they are wanting to change IP addresses for security reasons. So could someone tell me how I would make these changes without breaking everything? Is there a way to change the IP in one spot and everything follow suite or is it going to be more complex than that? -
If the VFD is being controlled by the PLC then no, if will not be that easy. The PLC has a very specific network configuration that allows it to control the VFD, and likely other devices such as remote I/O, vision inspection systems, weighing scales, etc... It can be done but it would need to be planned out. I'm guessing these devices are on your corporate network? If so, is IT trying to isolate these devices from the corporate network? That would be a good plan. -
After some more research I found out the Weintek mTV-100 is designed for this. It links to your HMI and creates a HDMI output for your TV/monitor. I will quote my project with the mTV-100 and keep you up-to-dateif the customer want to go for this option. Rene -
Hello, I am being told by IT to set new IP addresses for many devices, starting with some VFDs and later PLCs. Is this as simple as changing the IP address with the keypad on the VFD, and in the settings of the PLC? Will the PLC programs that use VFD tags need modified or will they see the changed IP address?

Definitely use a buffer tag and make sure the tag the HMI reads is always a valid value. Do all of your intermediate calculations and then write the HMI tag once with the final result. I ran into this when building a message display to switch between active alarm messages. When transitioning from "no message" to a newly active message, it would sometimes flicker to the last message (which was no longer valid). An intermediate holding tag is what sorted it. You'd be surprised how often it will display incorrectly. -

Thanks @BE! Somewhy it only shows the black box when double clicked, so it did not notice that! Thanks for helping! -
Hi guys, I need a software to test an old Schleicher PLC system. There is a P03-CPU/20 unit in it. As far as I know, I need Prodoc 5 or Multiprog. Does anyone have an idea where to get any of these? Zsolt Horváth
