Purpose
Following a restart, the configuration in the operating unit is replaced by a different
one. The new configuration is downloaded from the configuration computer to the
operating unit.
The following options are available for downloading a configuration:
Start downloading manually during the operating unit initialization phase
Start downloading automatically while the operating unit is in operation
Start downloading via a correspondingly configured operating element while the
operating unit is in operation (refer to the Chapter 6.1)
Start downloading manually during the operating unit initialization phase
Step Procedure
1 Connect the interface IF1A (RS232) or IF1B (RS485) on the operating unit to the
configuration computer, according to the setting in the Configuration menu
(Figure 3-2, Page 3-5), using an appropriate standard cable.
2 Switch on the power supply for the operating unit.
3 In the operating unit initialization phase, the menu illustrated in Figure 3-1
appears briefly. Touch the
Download button to set the operating unit to Download
mode before it is initialized.
The operating unit displays the message
Connecting to host
until it receives
data from the configuration computer or the button Cancel is pressed.
If the message
Connecting to host
does not appear, it is possible that the
option for Download mode has been set incorrectly (refer to the note on Page
3-6).
4 If downloading should be performed via an MPI connection, set the OP address
and transmission rate valid for the operating unit on the configuration computer
(refer to the note on Page 3-4).
Start data transfer to the operating unit from the configuration computer.
The configuration computer checks the connection to the operating unit. If the
connection is not available or defective, the configuration computer issues the
corresponding error message.
If downloading from the configuration computer is interrupted due a compatibility
conflict, please proceed according to the description in the Chapter 10.
If the connection is correct, the new configuration is downloaded to the operating
unit. Following successful downloading, the operating unit restarts and displays
the start screen of the configuration that has just been loaded.
