4.1.3 Relays, function relays
easy has nine different types of relay for wiring in a circuit diagram.
You can set the switching behavior of these relays by means of the coil
functions and parameters selected.
The options for setting output and marker relays are listed with the
description of each coil function.
The coil functions and parameters are listed with the description of each
function relay.
￫
In order to ensure compatibility with the easy400 and easy600
devices, each easy500 and easy700 logically supports all relay
types internally. If a relay type is not supported by the device,
the switching state of the contacts is always set to zero, i.e.
• devices without a clock. The contacts (N/O contact) of the
time switches are always set to logic 0.
The advantage of this process is that you can use the same
circuit diagram on all easy500, easy700, easy-AB, easy-AC,
easy-DA and easy-DC devices. Furthermore, you can use
outputs that are not physically present as markers.
