5.1.1 Precautions of Testing When Using In-house Equipment
When using in-house test equipment for debugging, the test environment may be
different from the target equipment.
● Style of CPU module
When debugging a new system, the FCN-500 or FCN-RTU of the in-house test
equipment used for debugging may be of an older version and its style number of
the CPU may be different from that of the target equipment.
On the other hand, when testing a modification of an existing system, the production
FCN-500 or FCN-RTU may be old and the style code of its CPU may differ from that
of the in-house test equipment.
A control application can be debugging using in-house test equipment whose CPU
style code differs from that of the target equipment or production equipment,
provided some restrictions and precautions to be described later are observed.
• How to check style code of CPU
Connect to the FCN/FCJ Maintenance homepage using a Web browser to
display the Top Page as shown in the figure below.
On the Top Page, check the displayed Type, which is enclosed by a blue box
below.
In the above figure, "S1U" is displayed after the model name (“NFCP502-W05”)
of the CPU module, indicating the latest S1 style CPU.
