1.6.2 Opto signal properties
Opto Signal
Each opto input can be selected and used for programming in PSL. Activation of the opto
input will drive an associated DDB signal.
For example activating opto input L1 will assert DDB 032 in the PSL.
1.6.3 Input signal properties
Input Signal
Relay lo
gic functions provide logic output signals that can be used for programming in PSL.
Depending on the relay functionality, operation of an active relay function will drive an
associated DDB signal in PSL.
For example DDB 671 will be asserted in the PSL should the active earth fault 1, stage 1
protection operate/trip.
1.6.4 Output signal properties
Outpu
t Signal
Relay logic functions provide logic input signals that can be used for programming in PSL.
Depending on the relay functionality, activation of the output signal will drive an associated
DDB signal in PSL and cause an associated response to the relay function
For example, if DDB 409 is asserted in the PSL, it will block the sensitive earth function
stage 1 timer.

1.6.5 GOOSE input signal properties
G
OOSE In
The Programmable Scheme Logic interfaces with the GOOSE Scheme Logic (see S1 users
manual) by means of 32 Virtual inputs. The Virtual Inputs can be used in much the same
way as the Opto Input signals.
The logic that drives each of the Virtual Inputs is contained within the relay’s GOOSE
Scheme Logic file. It is possible to map any number of bit-pairs, from any subscribed device,
using logic gates onto a Virtual Input (see S1 Users manual for more details).
For example DDB 224 will be asserted in PSL should virtual input 1 operate.
