SN-RN combination for bit exchange on the NET
•
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.
•
Reading using RN
The RN (Receive NET) NET operand is used to receive the bit data that
another NET station 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:
•
on the sending station and receiving station use the same operand
number for each SN/RN pair to be formed.
•
in the circuit diagram of the sending station you set for the SN operand
(coil) the station number (NET ID) of the receiving station.
•
in the circuit diagram of the receiving station you set for the RN operand
(contact) the station number (NET ID) of the sending station.
RN-SN 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.
NET operand GT.. (receive), PT.. (send) and SC.. (set date and time)
The function blocks are of data type 32-bit. They only function if the NET is
operating correctly (
section 10, “Diagnostics possibilities”, page 329).
