Operator Panel OP3
Edition 11/99
In recommissioning, the configuration loaded on the OP3 is replaced with
another. This can be done either by using the RS232 interface or the MPI. For
the MPI, the configuration computer – that is, a PC or PU – must be equipped
with an MPI card.
To recommission the OP3, proceed as follows:
RS232 MPI
1. Connect the RS232 interface of
the OP3 to the COM1/2 serial
interface of your PC or PU. Interconnect the MPIs of the OP3
and the PC or PU.
To do this, use the serial
connecting cable supplied with
the OP3. To do this, use the MPI
connecting cable supplied with
the OP3.
2. When connecting via the S7 bus connector, connect the power supply
to the OP3. To do this, use either the 24-V power supply cable
supplied with the OP3 or one of the two plug-in power supply units
referred to in Section 15.2.
3. Call standard screen System
→
OPMode and select the mode
Transfer MPI-Trans
The OP3 prompts you to enter the system administrator’s password
(default: 100) and waits for a download operation from the PC or PU
after you type it in.
If this standard screen is not available in your configuration,
press the following three keys simultaneously while turning on the
OP3’s power supply
ESC
This key combination deletes the current configuration. The OP3
loads the English-language standard screens.
You use them to enable Transfer mode.
4. Start the download operation on the PC or PU. With a proper
connection, downloading of the configuration commences to the OP3.
If the connection is not in order or if a connection has not been made,
a corresponding system message is issued.
The settings required in ProTool for the download operation will be
found in the User’s Guide ProTool – Configuring Text-based Displays.
5. If the download operation is successful, the OP3 re-starts and goes to
message level.
