4.2.6.1 Rules for wiring relay coils
To ensure a clear overview of all relay states only assign the same coil
function once to a relay (
ä, S, R). However, retentive coil functions such as ä,
S, R can be used several times if required by the circuit diagram logic.
Exception: When using jumps to structure a circuit diagram, this coil function
can also be used effectively several times.
4.2.6.2 Relay with contactor function Ä
The output signal follows the input signal directly, the relay operates as a
contactor.

Representation in easy:
• Output relays Q:
ÄQ1 to ÄQ8 (depending on type)
• Markers M, N:
ÄM1 to ÄM16, ÄN1 to ÄN16
• Function relays (Text) D:
ÄD1 to ÄD16
• Output relays S:
ÄS1 to ÄS8
• Jumps:
Ä:1 to Ä:8
