Model 2400S Transmitters for PROFIBUS-DP
Connecting with ProLink II or Pocket ProLink Software
4.3 Configuration upload/download
ProLink II and Pocket ProLink provide a configuration upload/download function which allows you
to save configuration sets to your PC. This allows:
• Easy backup and restore of transmitter configuration
• Easy replication of configuration sets
Micro Motion recommends that all transmitter configurations be saved to a PC as soon as the
configuration is complete. See Figure C-1, and refer to the ProLink II or Pocket ProLink manual for
details.
4.4 Connecting from a PC to a Model 2400S DP transmitter
To connect to the Model 2400S DP transmitter using ProLink II or Pocket ProLink, you must use a
service port connection.
4.4.1 Connection options
The service port can be accessed via the service port clips or the IrDA port.
The service port clips have priority over the IrDA port:
• If there is an active connection via the service port clips, access via the IrDA port is disabled.
• If there is an active connection via the IrDA port and a connection attempt is made via the
service port clips, the IrDA connection is terminated.
Additionally:
• Access via the IrDA port may be disabled altogether. In this case, it is not available for
connections at any time. By default, access via the IrDA port is disabled.
• The IrDA port may be write-protected. In this case, it can be used only to retrieve data from the
transmitter. By default, the IrDA port is write-protected.
See Section 8.10.2 for more information or to change these settings.
4.4.2 Service port connection parameters
The service port uses default connection parameters. Both ProLink II and Pocket ProLink
automatically use these default parameters when Protocol is set to Service Port.
Additionally, to minimize configuration requirements, the service port employs an auto-detection
scheme when responding to connection requests. The service port will accept all connection requests
within the limits described in Table 4-1. If you are connecting to the service port from another tool,
ensure that configuration parameters are set within these limits.
