Should we assume CMORE?

Sorry guys its a c-more micro 4 "

What plc driver, and what address? The helpfile should show this. Typical is that these are read only: Input Bits, Analog Inputs, and System Registers.

My issue as I have found is that I am trying to address the push button on the HMI to an X input. I was told it needs to be a C input. I re-addressed the button and programmed my DL06 processor to have the C inputs in parallel to my X inputs. But it still didn't work.
Any ideas guys?

What PLC driver are you using???????
As a test I just created a new 4 " micro project using k-sequence to an AD plc, added a pushbutton object addressed to C0 and an indicator light object addressed to X1, and both showed up in the tag database as R/W and I didn't see any way to change either to read only.
Does it work right in Cmore simulator?

I think the Read Only or Read/Write status is inherent in the type of data in the PLC and the display software is just showing that fact.
iadapt - please zip and post your display and PLC projects for help.

Agreed Bernie. I made another test project with AD Modbus and both addresses showed R/W.
I then created a project with Modicon Modbus, and that one had to pick a Modbus address type, and then you could get a "read only " type to show up in the tag database.

You should be able to write to X or C bits with no issue. There is something else going on.

Update guys, I solved the HMI issues by parallel programming my X inputs with C instructions. Apparently the HMI a C-More cannot function the inputs properly when connected to a DL06 processor. I odnt know if any other processors react the same as this one to the HMI. Whne I used an AB Micrologix 1000 I didnt have any issues like this. Curious to me why I do wiht Auto Directs processor?

You shouldn't try to write to the inputs or outputs from an HMI with any PLC. It's just asking for trouble.
