Procedure
Address setting is incorrect.
BCU
RY
Match address setting between BCU and relay.
Avoid duplication of address with other relay.
Transmission baud rate setting is
incorrect.
BCU
RY
Match transmission baud rate setting between
BCU and relay.
Start bit, stop bit and parity settings of
data that BCU transmits to relay is
incorrect.
BCU
Go over the following settings by BCU. Relay
setting is fixed as following settings.
- Start bit: 1bit
- Stop bit: 1bit
- Parity setting: even
The PRTCL1 setting is incorrect. (The
model with PRTCL1
setting.)
RY
Change the PRTCL1 setting. Relation between
PRTCL1 setting and available transmission
protocol is referred to the following table.

RS485 or optical cable interconnection
is incorrect.
Cable
- Check the connection port.(CH1/CH2)
- Check the interconnection of RS485 A/B/COM
- Check the send and received interconnection of
optical cable.
The setting of converter is incorrect.
(RS485/optic conversion is executed
with the transmission channel, etc.)
Converter In the event of using G1IF2, change the DIPSW
setting in reference to INSTRUCTION MANUAL
(6F2S0794).
The relationship between logical “0/1” of
the signal and Sig.on/off is incorrect. (In
the event of using optical cable)
BCU
Check the following;
Logical0 : Sig.on
Logical1:Sig.off
Terminal resistor is not offered.
(Especially when RS485 cable is long.)
cable
Impose terminal resistor (150[ohms]) to both ends
of RS 485 cable.
Relay cannot receive the requirement
frame from BCU.
(The timing coordination of sending and
receiving switch control is irregular in
half-duplex communication.)
BCU
Check to secure the margin more than 15ms
between receiving the reply frame from the relay
and transmitting the next requirement frame on
BCU.
1 Communication
trouble
(
IEC103
communication is
not available.
)
The requirement frame from BCU and
the reply frame from relay contend.
(The sending and receiving timing
coordination is irregular in half-duplex
communication.)
BCU
Check to set the time-out of reply frame from the
relay.
Time-out setting: more than 100ms (acceptable
value of response time 50ms plus
margin)
