Hi,

I know we can set the precision of a value field on the HMI. Is there a way to allow the PLC to control the 'Format Pattern' of a field dynamically?

I am trying to control how the data is displayed on the HMI, so it may or may not have a decimal place.

Thank you.

Hi!

First of all, which software are you using?

Br!

Tiaportal v18

CPU 1214C DC/DC/DC firmware v4.6

HMI KTP700 Basic

HMI KTP700 Basic

What you are thinking of doing is not going to work on the KTP700 Basic.

But there are viable workarounds. Choose between:

1. Have the PLC give the HMI a STRING to display. The PLC then has full control over how the value is displayed. This is more complicated but offers the most flexibility.
   
   
2.  Place multiple IO fields on top of each other. Use the visibility animation to show the IO field that has the correct decimal placement. This is easy to do if there are only a few values with few display variations.

What are your thoughts?

Hi,

Thanks for your reply.

I think I may choose option 1 as a way of controlling how a value is viewd on the HMI.
