STATE REPLICATOR (RIO)
The Master modem is fitted with a pair of digital inputs replicated through PLC communication to the selected digital
outputs (bistable relay) of the Slave modem. Using a serial parameterization terminal, you can set which input will
be replicated on which output, or you can define that an input will be negated on a particular output. Once the power
supply is on, the relay remains in the same state as without power and when communication is established the relay
switches to the state corresponding to the particular input within few seconds. When communication is interrupted, the
output relay switches to the state defined as the emergency state. Once communication is re-established, the output
relay switches to the state corresponding to the particular input again.

True value read at IN2 input
True value on DIGIOUT2.
LED indicator on, the device receives information on Log1 from
the counterparty (the state corresponds to the relay state: ON/
OFF)
4 - Red
True value read at IN1 input
True value on DIGIOUT1.
The LED indicator is on, the device receives information on Log1
from the counterparty (the state corresponds to the relay state:
ON/OFF)
5 - Blue
The internal system of status machine interruptions and timing running in the device. The LED indicator blinks, changes its state
every 1 s.
6 - Blue
The device has sent the packet (the state change indicates
sending)
The device has received the packet (the state change upon
receiving the packet).
7 - Red
In case the LED indicator is on or blinks, the device has initiated the peripheries and the processor started communicating with
the modem
∫
The LED indicator is on: DIO sends status information about the digital inputs and rewrites the Switch data on the output – the
DIO device receives the data through the RS485 input line, encodes the data into the packet sent by PLC communication and
writes the Switch data on the RS485 output.
∫
The LED indicator blinks: a console running in the DIO device – the PLC packets transfer only status information about the digital
inputs.
8 - Blue
OFF – the device is used as the Master digital input
ON – the device is used as the Slave digital output
