Getting Familiar With Your BASIC Interface Software 27
If you select a DH-485 port, the following four pieces of information
are displayed:
• Availability of the BASIC software DH-485 connection
• DH-485
• RSLinx function return code
• DH-485 connection return code
For example, DH-485 0 0 indicates that the BASIC software is
connected to a BASIC module via the DH-485 network, and that there
are no problems. If a non-zero value is ever displayed for either the
RSLinx function return code or the DH-485 connection return code,
then the BASIC software has lost the connection to the BASIC module.
Further, X DH-485 0 0 indicates that the BASIC software was not able
to open a connection to a BASIC module.
