The following table shows the relationship between the SN and RN operands:
The counter function block C1 is assigned the following parameters:
To reset the function block in line 2 to zero, select the coil function RE
(Reset).
Once the counter function block has reached the value 10, we wish to set
output 1 on device 3 (Pico-Link ID 3) to “1”. The existing program must be
extended by one line (see the following figure).
Bit input RN 1 Bit input RN 2
Send bit via 1SN1 from Pico-Link ID 2 Read sent bit via 2RN1 to Pico-Link ID 1
1: Bit is meant for station 1 (Pico-Link ID 1) 2: Bit comes from station 2 (Pico-Link ID 2)
SN: The bit is sent RN: The bit is read
1: Operand number (is between 1-32) 1: Operand number (is between 1-32). Must be identical to
the number of the SN operand.
