6.14.2 Changing MPI/PROFIBUS DP settings
Introduction
The communication settings for MPI or PROFIBUS DP are defined in the HMI device project.
In the following cases, the transfer settings might have to be changed:
● The first time the project is transferred
● If changes are made to the project but are only applied later
NOTICE
Transfer mode using MPI/PROFIBUS DP
The bus parameters are read from the project currently loaded on the HMI device.
The settings for MPI/PROFIBUS DP transfer can be modified. The following steps
are required:
• Close the project.
• Change the settings on the HMI device.
• Then return to "Transfer" mode.
The changed MP/PROFIBUS DP settings will be overwritten in the following cases:
• The project is started again
• A project is transferred and started
Transfer settings
If the HMI device is in "Transfer" mode while changes are made to the transfer settings,
the settings only go into effect after the transfer function is restarted.
