5.2 Initial Processing
This section explains the initial processing of the Ethernet module.
5.2.1 Initial processing
The initial processing enables data communication with an external device by setting
the parameters required for data communication via the Ethernet module.
Set the following parameters in the sequence program, write them to the Ethernet
module; the initial processing of the Ethernet module is then performed by one of the
following methods.
• Re- initialization request (Write the re-initialization request (0001
H, 0002H, 0005H or
0006
H) to BFM #1600.)
• Power ON the Ethernet module again.
(1) Parameters required for initial processing
• "Operational settings" :(See Section 4.6.)
• "Initial settings" :(See Subsection 5.2.2.)
(2) Confirmation of initial processing result
If the initial processing does not complete normally, correct the above parameter
setting value and write to the Ethernet module. Then re-initialize the Ethernet
module.
