Program example
This example explains a program for open processing/close processing when
Active open is selected in the Open system setting.
(1) Execution environment for the program example
(a) The Ethernet module is connected to the second special module. (The unit
number is setting 1)
(b) The unit number specified at the sequence program and FX Configurator-EN
is 1.
(c) Make Operation settings in the following manner.
Communication data code : Binary code (BFM#24 b1 : OFF)
Initial timing
IP address
(d) Make open settings in the following manner.
Protocol
Open system
Fixed buffer
Fixed buffer communication
procedure
Pairing open
Existence confirmation
Local station Port No.
Transmission target device
IP address
Transmission target device
Port No.
(e) The following contact signals are used in the program.
Ethernet module status
Connection No.1 open/close status and instruction
(f) The area enclosed with
the [Open settings] Ethernet module parameters are not set for
FX Configurator-EN.
This part of the program is not required when the [Open settings] parameters
are used for FX Configurator-EN.
(2) Outline of the program example
(a) After each parameter is set in FX Configurator-EN or the sequence program
and written to the Ethernet module, re-initialize or power ON the module
again and confirm the completion of the initial processing via buffer memory
operations.
(b) The Ethernet module performs the open processing for connection No. 1 to
the external device set in the [Open settings] or control data.
(c) The close processing for connection No. 1 is performed according to the
close instruction to the Ethernet module or the close request from the
external device.
