The functions of the DIP switches on the memory unit are indicated in the table
below.
• SW1
Switch Function
SW1 1
Automatic transmission (writing from the memory
OFF: Not executed
SW1-1
Automatic transmission (writing from the memory
unit to the PT)
ON : Executed
SW1 2
Automatic transmission (writing from the PT to
OFF: Not executed
SW1-2
Automatic transmission (writing from the PT to
the memory unit)
ON : Executed
SW1 3
Manual transmission (Direction of transmission
OFF: Not executed
SW1-3
Manual transmission (Direction of transmission
and bank used selected at the PT touch panel)
ON : Executed
OFF: Screen data
SW1-4 Data type to transfer ON : System
program
• SW2
Switch Function
SW2 1 Disable/enable writing to PT
OFF: Disable
SW2-1 Disable/enable writing to PT
ON : Enable
SW2 2 Disable/enable writing to the memory unit
OFF: Disable
SW2-2 Disable/enable writing to the memory unit
ON : Enable
SW2 3 Area (bank) selection of automatic transmission *
OFF: Bank 0
SW2-3 Area (bank) selection of automatic transmission. *
ON : Bank 1
SW2 4 System/Screen simultaneous transmission
OFF: Disable
SW2-4 System/Screen simultaneous transmission
ON : Enable
* The memory unit stores system program or screen data for one PT in each of
areas (bank 0, bank 1). (The total data storage is for two PTs.) SW2-3 sets which
of these two banks is used for automatic transmission.
Reference: S The DIP switch function of the memory unit is supplemented to NT31/NT31C
with the V
j suffix.
S In the following cases, a mode setting error occurs.
• More than one of the SW1-1 to SW1-3 switches are set to ON.
• None of the SW1-1 to SW1-3 switches are set to ON.
S In the following case, a protect setting error occurs.
Transmitting to the write destination has been disabled by the setting for
SW2-1 or SW2-2.
S In the following cases, a data transmission error occurs.
• An attempt is made to transmit data other than the system program to PT
