5. Programming on the device
5.4 Working with contacts and coils
SN-RN combination for bit exchange on the NET
l
Writing via SN
The NET operand SN (Send NET) is used for sending bit data from one NET station to
another. To do this you select the SN operand in a coil field.
l
Reading using RN
The RN (Receive NET) NET operand is used to receive the bit data that another NET sta-
tion has sent. To do this you select the RN operand in a contact field.
As the RN and SN must always be used in pairs, the following rule applies:
l
on the sending station and receiving station use the same operand number for each
SN/RN pair to be formed.
l
in the circuit diagram of the sending station you set for the SN operand (coil) the sta-
tion number (NET ID) of the receiving station.
l
in the circuit diagram of the receiving station you set for the RN operand (contact)
the station number (NET ID) of the sending station.
SN-RN example
NET station 2 sends the status of the P button P01 via SN1 to NET station 1.

The relevant circuit diagram is as follows:
On NET station 1 the status of P1 is associated via RN01 as a count pulse for the
counter relay C01.
