Hi, Expert

Can I have a Runtime Advanced version?

Thanks

“Simple Samples” are small projects that demonstrate simple features. The target is give a quick overview about the theme and be used as start point for related discussions. Follow there are a short description and the configuration main steps.

Description:

One of news of TIA V14 is the possibility toread and force a connection status by using the variables “@<name of connection> @ConnectionState” and “@<name of connection>@ForceConnectionState”.

These variables should be created manually. The system help (Information system → Visuzalize process → Communicating with PLCs → Network and connections → Configure networks and connections → Setting up switch on / switch off a connection in Runtiime), shows how to configure them. I copy here, part of the configuration steps:

“

Requirement

The "HMI tags" editor is open.

Procedure

To create tags for controlling a connection in Runtime, follow these steps:

Create the tags for connection control in the following text format:

"@< ConnectonName >@ConnectionState", e.g. @HMI_Connection_1@ConnectionState

This tag contains the current state of the connection. You only have read access to this tag.

"@<ConnectionName>@ForceConnectionState", e.g. @HMI_Connection_1@ForceConnectionState

You set the new status of the connection in Runtime using this tag. The start value for @HMI_Verbindung_1@ForceConnectionState is 0 (not connected) or 1 (connected).

Configure the tag according to the following specifications:

Data type: "DWord"

PLC tag: None

Connection: HMI_Connection_1

PLC name: Not relevant

Address: %DB40000.DBD65000 (any unused address)

Access type: Absolute access

“

Requirements:

TIA V14.

Project:

Hi Denilson,

I just tried this approach with a mobile panel (277F) without success. If I use a non-existent PLC address for @PLC@ConnectionStatus HMI tag (PLC is the name of my connection), HMI throws an error about bad tag addressing.

What values the DWord tag is supposed to have? Should it work for comfort and mobile panels as well? 

Thanks,
