This Technical Note describes the hardware requirements for updating firmware on obsolete SCADAPack models that include the 5203 & 5204 CPU boards. The 5203 contains 2 RS-232 communication ports and the 5204 contains 1 RS-485 port and 1 RS-232 communication port. Both hardware boards where manufactured as part of SCADAPack, SCADAPack Light, SCADPack Plus and Micro 16 models.
Older versions of the 5203/5204 board has a place for 4 40-pin integrated circuits. These are labelled as U13, U14, U15 and U10 from left to right. There are also 2 jumper pins J3 and J4. These components determine the flash and RAM that is currently installed on the SCADAPack. In order to update the firmware on a 5203/5204 board to the latest released version, the SCADAPack must have 1024 bytes of RAM (OS & APP) installed.
U15 & U10 along with the jumper pins J3 and J4 determine how much RAM is installed. These chips can range from 128K - 512k each. Refer to to the table below to determine how much RAM is installed
|Total RAM||OS RAM (U10)||Jumper J4||APP RAM (U15)||Jumper J3|
If jumpers J3 and J4 are currently in the "Right" position, then you will need to update one or both of the RAM chips in U15 and U10. Contact your Schneider Electric Telemetrey & Remote SCADA Solutions Sales representative for part numbers and pricing or email SalesTRSS@Schneider-Electric.com
If the RAM installed is not 1024K, then 1.65 is the highest version of firmware that can run on the controller. Please contact Technical Support at firstname.lastname@example.org to obtain firmware version 1.65.
If you are updating a SCADAPack with the latest version of Realflo, IEC-61131 programming environment or simply updating the firmware, then ensure you have both U15 and U10 chips installed and they are both 512K each.
|RISK OF UNEXPECTED OPERATION |
Installing the latest firmware on a controller that does not have the full 1024k of memory will cause the controller to become unresponsive.
The part number to upgrade OS RAM (U10) is TBUM297232. The part number to upgrade APP RAM (U15) is TBUM297230. SCADAPacks that contain firmware 1.32 and older will require a flash memory upgrade (U13 & U14) with TBUM327035 in conjunction with the RAM memory upgrade.
