Download to project module type only

GXDP will allow a download only to the same module type as specified in the project. If the

module found in the specified slot of the target PLC rack does not match that of the project, an

error message is displayed.

If the user wants to download the project to a different module type, the project must first be

converted to the type of the connected module. This is done by selecting the

Change Master

Type

menu item.

For QnPRH redundant systems

If the connected PLC is a QnPRH, GXDP automatically checks whether both PLCs of the

redundant system are accessible by using the tracking cable and also checks the current backup

mode. The procedure for download is adapted according to the result of these tests

1. ‘Backup’ mode and both PLCs connected: the user is asked for confirmation to update both

master modules. If the user confirms, the system is automatically switched to ‘Separate’

mode and default device tracking is turned off. Then the configuration is downloaded to the

master in the control as well as in the standby system. After the download, the system is set

back to the original state.

2. ‘Separate’ mode and both PLCs connected: the user is asked, whether the configuration of

both master modules or only of the one in the locally connected PLC should be updated. In

both cases device tracking is turned off, while the configuration is downloaded to the

master(s). After the download, device tracking is enabled again.

3. ‘Debug’ mode or only one PLC connected: only the master in the connected PLC is

updated.

AutoRefresh Update

If the user has selected 'AutoRefresh (Update of CPU)' or 'AutoRefresh (Update of GID Project)' in

the 'PLC and GID Settings' dialog, the autorefresh settings are updated, after the configuration
