communication procedure :
Pairing open
Existence confirmation
Host station Port No.
6) Fixed buffer No.1 receive data.
: Stored in D1000 to D1015
7) Fixed buffer No.1 receive instruction complete status.
: D100
POINT
Make sure to have sufficient device memory according to the maximum data length
sent in order to prevent device areas used for other purposes from being
overwritten by the received data.
(2) Outline of the program example
(a) Send program (Ethernet-1st station side)
1) After setting each parameter with FX Configurator-EN (GX Developer) or
a sequence program and writing to the Ethernet module, power ON the
module again, or confirm that the initial processing is completed via
buffer memory operations.
2) Perform open processing (Active open) for connection No. 1. ( 1)
3) Communicate data from the PLC using fixed buffer communication (no
procedure sending).
4) After data sending is complete, perform close processing for
connection No. 1. ( 1)
1 Use the program example described in Section 5.6.1, "Active open
processing/close processing" for the sequence program that
executes the open processing/close processing.
Make sure to change the "Fixed buffer communication" setting
from "Procedure exist" to "No procedure".
