Special information and instructions for configuring
the control system
Private range
Provision is made in the event configuration (see Section 2.3) for the user to enter
his own private IEC 60870-5-103 definition for each REB500 signal.
The input fields for REB500 signals covered by the public part of the standard (see
Section 3.2) have a bright yellow back-ground their default setting ‘0’ for both IEC
function type and in-formation number. All other signals receive the presetting 0
for the IEC function type and the information number. A signal de-fined for
protocol 60870-5-103 that is not in the public range and has ‘0’ set for function
type and information number is transmit-ted via the generic part of the protocol.
