Precautions on Setting the Connection Parameters
The following restrictions apply to the input values of connection parameters:
• Duplication of the Local Station's Port Number
The local station port number and connection type combination set in the connection
parameters must not be used for any other connection parameters.
• Duplication of the System Port
When Connect Type is set to TCP in the connection parameters, the local station's port
number must not be the same as the diagnostic port number.
• Open Mode
When DST. IP Address is set to all zeroes in the connection parameters, DST. Port must
be set to zero and Target Ethernet Address must be set to all zeroes.
