I am using a Siemens S7-1200 with VTScada and the Siemens TCP driver. Occasionally, certain tags will be modified fine in VTScada, but they are not written to the PLC program (although they should be). Other times they are changed correctly. It seems to be somewhat random. Would appreciate any advice anyone could give that might be causing this.
Thanks.

We are trying to configure a firewall between the primary and the DMZ (Pivot) server. The DMZ (Pivot)server will provide read-only remote access to operators. We are licensed for 25K tags. What is a good estimate for throughput between the primary and dmz server?

Still new to VTScada.

I have an I/O tag of length word in VT scada with an output address to a register in the PLC. I want to set/reset a bit at a desired position in that tag if an alarm status tag is true. What is the best way to do this?

Thanks

I've created a Custom Type that contains five analog tags - Value, EU_Max, EU_Min, L_Alarm, H_Alarm. Their PLC addresses are based on a custom Parameter called 'BaseAddress'. Address expression example:

\baseaddress + ".Value"
I've also tried:

Pickvalid(Concat(..\baseaddress, ".Value), "")
and

Concat(getphrase(..\baseaddress), ".Value")
etc

Have also tried checking and unchecking

If I open the Historical Data Viewer page and turn a tag's trend visibility off by clicking the eyeball icon and then close the page, the trend visibility is set to disabled globally. You go to a page showing that tag's value and click on it to open the plot and it is not visible. Not only that, but any other user will also have that tag's plot not be visible.

How can I configure the plot vis

Hello, I am new to VTScada. I have an Alarm Word from the PLC, where each bit represents an individual fault. I'd like to read the entire Alarm Word as a single tag in VTscada and create alarms for each individual bit. I have found the expression Bit([HMI Alarm Word],2) for example to work as an expression, but I'm not sure where/how to enter this to create the Alarm. Thanks.

Hi,

I am having an issue connecting to a Koyo DL330 PLC via serial. I have it setup with the correct station addresses and COM port parameters, and it appears to be reading my register R16 correctly. However, writing to the tag fails. Sniffing the serial packets, it appears that the driver is trying to pull data from 2 8-bit registers when I only want to pull from one and I believe this is w
