Hardware and firmware versions of the PCD3.Mxxx0
The firmware versions of the PCD3.Mxxx0 are usually downward compatible in
terms of hardware, so that even old CPUs can be equipped with new firmware to
benefit from new functions. This property is highly valued, and we try to keep it as
long as possible; however, we cannot guarantee it.
The firmware of the PCD3.Mxxx0 is stored in a flash EPROM, which is soldered to
the motherboard. A firmware update is possible by downloading a new version with
the PG5. The procedure is as follows:
● Download the current firmware version from
●
Establish a connection between the PG5 and the CPU, as for the download of
an application (depending on the available options such as serially with PGU
cable, modem
1)
, USB, Ethernet)
● Open the online configurator and go offline
●
In the Tools menu, select Download Firmware, then use the browse function to
select the path to the file of the new firmware version. Make sure only one file is
selected for download
●
Start the download
●
After the download, the power supply of the Saia PCD
®
must not be interrupted
for 2 minutes (CPLD programming sequence). Otherwise it may happen that
the CPU is blocked in such a way that it has to be returned to the factory.
While the Run/Stop LED flashes slowly, the download process is not yet com

pleted. Only when it flashes fast, the programming is finished.
1) A modem connection is not reliable. It may be that a modem is blocked in such a way that remote access is no
longer possible. In such cases, local intervention will be necessary. The other connection options are preferred.
