4-7-1 Node Address, Baud Rate, and Output Hold/Clear Settings
This section describes the Slaves’ node address setting, baud rate settings,
and hold/clear outputs for communications error setting. These settings are
made using the following pins on the DIP switch.
Node address setting: Pins 1 through 6
Baud rate setting: Pins 7 and 8
Output hold/clear setting: Pin 10 on DIP switch on bottom panel
(affects only outputs)
Node Address Settings Each Slave’s node address is set with pins 1 through 6 of the Slave’s DIP
switch. Any node address within the setting range can be used as long as it
isn’t already set on another node.
0: OFF, 1: ON
Note 1. Refer to
Appendix A Node Address Settings Table
for a complete table of
DIP switch settings.
2. 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 dupli-
cation error).
Baud Rate Setting Pins 7 and 8 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-
