Auto Open Processing - Panasonic FP2 ET-LAN Technical Manual

10.1.3 Auto Open Processing

What is Auto open processing?
-
Based on the information set by the setup tool (Configurator ET), the open processing is automatically
conducted to each connection of the ET-LAN unit when the power is supplied. When using the auto
open processing, open processing for each connection by the ladder program is not necessary.
In the auto open processing, open information for each connection as shown below is set using the
-
setup tool (Configurator ET).
Before using the auto open processing, confirm that the auto connection function is ON and a check
-
mark is not placed in "The connection 1 to 8 are set by ladder program" check box (Auto open
processing is valid.).
The check mark is not placed in this check box in the initial setting.
Setup window with the setup tool (Configurator ET)
-
In the auto open processing, the open processing is automatically conducted when the auto
initialization processing is completed. Therefore, the open request signal does not need to be ON for
each connection.
-
Whether the auto initialization processing is completed or not can be checked using the open complete
signal and the open error signal in the conventional I/O handshake area or in the shared memory
handshake complete signal area.

Note:
When the auto open processing is valid, the open processing using the ladder program is invalid.
-
Only the settings set by the Configurator ET is valid. At this time, the close processing cannot be
conducted.
When the auto open processing is valid by not selecting the check box for "The connection 1 to 8 are
-
set by ladder program" using the Configurator ET, the auto open processing is applied to all
connections. Therefore, the open processing cannot be set to "Valid" or "Invalid" for each connection
using the ladder program.
