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.
