6-4-2 Debugging with Display Messages
Debugging with Display Messages allows to confirm the send data format of
the SEND/RECV/CMND instruction and the ports to be used.
The samples of Display Messages when debugging network communications
are shown below.
6-4-3 Debugging with Local Communications
Debugging Method
When debugging network communications instructions with actual FINS
communications performed, FINS commands can be sent only within the
same computer. Thus to debug FINS communications, the CPU Unit of Fins-
Gateway will be regarded as a tentative destination.
Restrictions when CPU Unit of FinsGateway Is Specified
When the CPU Unit of FinsGateway is specified, there will be restrictions
caused by the differences of I/O memory. The I/O memory areas of the CPU
Unit of FinsGateway that can be specified by a SEND/RECV instruction are
shown below.
Name The number of I/O points Word Address
CIO area CIO32768 CIO0000 to CIO32767
DM area CIO32768 D00000 to D32767
