Procedure 4 Power Up Sequence - Panasonic MEWNET-F Technical Manual

5.3.5 Procedure 4 Power Up Sequence

Turn on the power to the system after completing the installation of the master and slave stations, wiring
with transmission cables and settings of station numbers and terminal stations.
Once the power turns one, the remote I/O control will be enalbed, and the operation can be confirmed.
(The settings on the CPU such as the I/O number allocation are available.)
Confirming the power up and remote I/O control
Procedure
1. Power up the remote I/O controlled slave stations.
2. Set the CPU on the master unit to PROG. mode.
3. Power up the master station system as the last step.
Note1) When you power up the master station, the COMM. LED (COM. LED) of all teh stations will flash
quickly.Please confirm.
Note2) When teh PROG. LED on the CPU is flashing, the remote I/O map may be already registered.
Confirmation
When a remote I/O map has not been registered in the CPU, I/O numbers are allocated automatically
only for the slave stations which have been turned on. (This is called the remote I/O control using
"Automatic allocation".)
(1)When starting up the system in the above procedure, the I/O number allocation using "Automatic
allocation" is as follows in the "Procedure 1" example.
(2) The operation turning on/off the I/O of each station can be confirmed by writing a sequence program
to the CPU of the master station or performing forced input/output.

-The left example is a case that
various settings such as I/O map and
base word number are the default
values.
-Master station: Master 1
Base word number: 64
* The starting number for the I/O
numbers of slave stations in the
master 1 system is 640.
