4.4 Start-up Parameters
The start-up parameters are directly assigned to the respective slots (RG..Ns) and are set during device configuration.
They are transferred automatically on start-up and during re-parameterization. The service data objects with a write
access in the object dictionary can be used during the start-up sequence. This is done by adding the required objects
as start-up parameters in the “Startup” tab of the device in TwinCAT, note that start-up parameters are not added
automatically. The value of the start-up parameters should be written in a little-endian format, i.e. if for example a
value of 660 decimal (02 94 hex) is required to be written, the value written should be 94 02.
Figure 15 Click new to add parameters (and their values) to the start-up sequence
The initialisation time of the NRGC-ECAT (from Pre-OP to OP) increases with the number of objects added to the start-
up sequence. Alternatively, all parameters can be assigned or re-assigned via a service data object. Check
‘Communications’ section for further information. If start-up parameters are left blank, the values saved internally in
the RG..Ns will be loaded.
The below parameters are available for all RG..Ns on the bus chain. The xx in the index represents the position (in hex)
of the solid state relay (RG..N) on the bus chain:
e.g 0x2 01 1 - 1

Note: ‘ TEACH Parameters’ and ‘ Load Running Hours reset’ should not be included as part of start-up sequence.
