Migrating from a legacy controller
Consider the following when migrating an application from a legacy controller
(POL400 / 600).
● Hardware IO mix: Evaluate ways to migrate hardware IO mix including
extension IO modules since C400 only supports 1 extension module. Consider
the IO types as well. For example, C400 analog input only supports NTC10K
and 0…10 V.
● Communication: Evaluate ways to migrate communication. C400 does not
support COM modules but has an inbuilt Ethernet port for BACnet, IC Cloud
and Modbus. The RS485 port supports Modbus and BACnet MSTP, process
bus is not supported.
● System features: C400 controllers do not support Eventlog. You can use
logged event in Climatix IC as an option, or consider Eventlog as Alarmlog.
Alarm snapshot is not supported.
● Application and object limitation: Check that there is enough memory (512 kB
for code and 1,200 objects) for previous applications to run on C400
controllers. Delete unneeded objects as applicable.
● Parameter save function: C400 does not have the parameter auto save
function upon power failure, application save function must be triggered by the
application to save parameters to persistent memory.
● Real time clock (RTC): As POL461.45/STD does not have an RTC, related
functions such as archive trend, archive and alarm history are not fully
supported. The clock needs to be re-adjusted upon power failure to support
these functions. POL467.75/STD and POL468.65/STD have on-board RTC.
5.1.3 ApplicationSave parameter
Application parameter storage concept
C400 controllers do not support object storage at power failure due to hardware
limitations (without super cap). If you need to store the object parameters, trigger
the ApplicationSave member in aoDiagnostic system object.
Refer to SAPRO Online help, SBT Climatix>Application>Storage and memory
concept for more information.
ApplicationSave Member
Use member 0x001B in aoDiagnostic to trigger ApplicationSave.
The member can be edited in Scope tools, in the SAPRO application of AccessDB,
or accessing the relevant object by an HMI.
