Auto Initialization Processing - Panasonic FP2 ET-LAN Technical Manual

10.1.2 Auto Initialization Processing

What is Auto initialization processing?
Based on the information set by the setup tool (Configurator ET), initialization processing is
-
automatically conducted when the power is supplied. When this processing is performed, initialization
processing using the ladder program is not required. Even if the initialization processing is set using the
ladder program, the setting is ignored.
In the auto initialization processing, initialization information and routing information as shown below
-
are set using the setup tool (Configurator ET).
- Under the condition that the auto connection function is valid, the initialization processing is
automatically conducted when the power is supplied to the programmable controller and the setting of
the initialization processing has been changed. Therefore, the initialization request signal does not
need to be ON.
-
Whether the auto initialization processing is completed or not can be checked using the initialization
complete signal and the initialization error signal in the conventional I/O handshake area or in the
shared memory handshake complete signal area.

Note:
When the auto connection function is valid, the initialization processing can be set only with the
Configurator ET. (The initialization processing cannot be set with the ladder program.) At this time, the
termination processing cannot be conducted.
