Initial Startup

Procedure
When the operating unit is started up for the first time, there is no configuration
loaded. Proceed as follows, observing the sequence, in order to download a
configuration from the configuration computer to the operating unit which is
necessary to put the unit into service:
Step
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.
Since no configuration has been loaded at this point, the operating unit
automatically switches to Download mode. 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).
3 If data is to be transferred via an MPI connection, set the following parameters
on the configuration computer:
OP Address: 1
Transmission rate: 187.5 kBaud
Start the 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, it 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 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.
