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

checked.

Upload Config. Image

GXDP tries to connect to a master module of the type set in the current project, using the selected

transfer setup. If the connection is established, the current configuration is read from the master

module and stored in binary format in the file, which the user has selected. Information stored in

the PLC CPU like autorefresh settings or POU code is not retrieved.

The configuration image can be used to configure another master module, if the original GXDP

project file is not available. The configuration image is downloaded a master with the

'Download

Config. Image'

function.

Note:

The information read from the master module cannot be used to create a GXDP project

file.

Download Config. Image

The user must first select a file with configuration image created by a previous upload ( see

'Upload Config. Image'

) or the corresponding export function of GXDP (see

'Export -> Config.

Image'

). This configuration must be compatible to the module type set in the current project.

GXDP tries to connect to the master module, using the selected transfer setup. If the connection

is established, the configuration image is written to the master module.

Command Start/Stop PROFIBUS

This item is used to manually start or stop the PROFIBUS DP cyclic data transfer of DPV0.

The current status of the connected PROFIBUS master is checked. If there is no active data

transfer, the user is asked to confirm starting the transfer.

If the data transfer is active, the user is asked to confirm stopping the transfer.

The cyclic data transfer is started and stopped by setting respectively resetting the Y0 (+ starting

I/O number) device of the master. If a PLC program, which starts the data transfer, is running,

while the user tries to stop the data transfer, the operation fails. An error message is displayed

and the user is informed of the possible access conflict between PC and PLC program.
