Waterproof Terminals (IP67)
Section 5-4
Node Address Setting
Each Waterproof Terminal’s node address is set in two-digit decimal with the
rotary switches. The 10’s digit is set on the left rotary switch and the 1’s digit is
set on right rotary switch.
Any node address within the allowed setting range can be used as long as it
isn’t already set on another node.
The Waterproof Terminal won’t be able to participate in communications if the
same node address is used for the Master or another Slave node (node
address duplication error).
Note
The Slave won’t be able to participate in communications if the same node
address is used for the Master or another Slave node (node address duplica-
tion error).
Baud Rate Setting
Pins 1 and 2 are used to set the baud rate as shown in the following table.
(These pins are factory-set to OFF.)
Note
1.
Always turn OFF the Slave’s power supply (including the communications
power supply) before changing the baud rate setting.
2.
Set the same baud rate on all of the nodes (Master and Slaves) in the Net-
work. Any Slaves with baud rates different from the Master’s rate won’t be
able to participate in communications. Furthermore, a node with an incor-
rect baud rate setting may cause communications errors between nodes
with correct baud rate settings.
Output Hold/Clear Setting
The functions of pins 3 and 4 differ for inputs and outputs, as shown in the fol-
lowing diagram. (Pins 3 and 4 are factory-set to OFF.)
Pin 3:
Reserved (Always OFF)
Pin 4:
As follows:
Inputs:
No function (Always OFF)
Outputs:
Hold/Clear outputs for communications error
OFF (Clear):
All output data from the Master will be cleared to 0 when a
communications error occurs.
ON (Hold):
All output data from the Master will be retained when a
communications error occurs.
