9. SOFTWARE UPDATE
9.1 Uploading/updating the software
The following methods can be used to update the fi rmware and acquire
the log fi les on pCO controllers:
•
SmartKey programming key;
•
pCO manager tool, a program installed on a PC.

mart key
The PCOS00AKY0 key is an electronic device used to program and service
the pCO sistema family controllers. PCOS00AKY0 simplifi es data transfer
between the controllers installed and a personal computer by exploiting
the high capacity fl ash memory for storing software applications, BIOS
and variable logs. The pCO is connected directly via the telephone
connector using the cable supplied, while to transfer the data to a
personal computer, the USB adapter code PCOS00AKC0 is required.
The power supply comes either via the USB port on the PC or from the
controller, therefore no external power supply is needed.

Programming the Smart Key via Personal Computer
The operating modes described in the table below can be confi gured
using a program on a PC. The program can also load the software to the
key or transfer logged data from the controller to the hard drive.
Type Function Mode button
B Update software from key to pCO (BIOS,
application program, parameters,...) Disabled
C* Copy software from pCO to pCO (BIOS,
application program, parameters,...) Switches the key from write
mode to read mode
D Read logs Disabled
E Read logged data and software from pCO
(BIOS, application program, parameters,...) Disabled
F Read logs Disabled
G Copy from pCO to pCO and read logs Switches the key to write
mode, read mode and read
logs mode
*: Default mode
Tab. 9.a
The key is factory-programmed in read/write mode (type C) so that it can
be used immediately to transfer software from one controller to another.
When the key is connected to the personal computer, the symbols have
the following meanings:
Flashing Waiting for connection to PC
Alternating
When connected to PC indicates
data transfer in progress
The programming key is compatible starting from BIOS version 3.43 and
BOOT version 3.01. For more detailed information on programming the
key, see to the pCO Manager manual.
Using the Smart Key with the pCO/μPC programmable controllers
Switch off the pCO, remove any peripherals connected in the pLAN
and plug the key into the telephone connector on the controller. When
switching on again, all the symbols light up momentarily and the buzzer
emits a beep. A few seconds later the key becomes operational. This
waiting period is indicated by the fl ashing of
. The controller then
enters programming mode and the start button is on steady; press the
button to start data transfer
Important:
•
if the key is type B, C or G (in write mode) pressing the start button will
immediately delete the software already loaded on the pCO.
•
Do not remove the key while data is being transferred to the key itself,
as the fi le being transferred will be lost and the corresponding space
will not be restored. To restore the original capacity all the fi les will
need to be deleted. If the key is type “C” or “G”, simply perform a new
application read operation.
Meanings of buttons/symbols
Flashing: the key is connecting to the pCO; during this phase, which
may last a few seconds, the start button is disabled
start Flashing: the key has detected the pCO and is checking the access
rights
start+
On steady: pressing the start button will start writing the software to
the pCO
start+
On steady: pressing the start button will start reading the software
from the pCO
start+
On steady: pressing the start button will start reading the logs from
the pCO
mode
On steady: for type C or G keys, pressed for 1 second switches from
read to write mode
Tab. 9.b
If the key is type C or G, pressing mode for 1 s switches from read mode
to read logs (G only) or write mode; the symbols (write to pCO),
(read from pCO), (read logs) refl ect the selected mode. If the key is not
type C or G, the mode key is disabled and the light is off . The start button
starts the read or write operation, which will be indicated by the fl ashing
of the corresponding symbol ( or ), at a frequency proportional
to progress. When the operation is completed, the buzzer will sound
intermittently for 2 seconds. Pressing the start button again will make the
buzzer sound without repeating the operation; to repeat the operation,
the key must fi rst be unplugged. In the event of an error, the symbol
comes on in combination with the other LEDs. The following table can
be used to fi nd the cause of the problem.
