①
Station No.
setting switch
Used to specify a station number. A total of 31 stations
ranging from 01 to 7F can be set. Use the U switch to set a
higher-level station number or the L switch to set a lower-level
station number.
②
Bit Rate
setting switch
Used to set a transmission speed.
0: 1.0 Mbps, 1: 0.5 Mbps, 2: 0.25 Mbps, 3: 0.125 Mbps
③
Slot No.
setting terminals
Used to set the number of I/O points (16, 32, 64, or 128 points)
per slot of the mount base.
If the mounted I/O modules have different numbers of I/O
points, set this number to the greatest one of the I/O point
numbers.
④
FIX/FREE setting
Used to set a partition (FREE or FIX) of the mount base.
Usually select “FREE.” If the I/O modules have a total of
2048 or more I/O points, select “FIX.”
When “FIX” is selected, the maximum number of input I/O
points and that of output I/O points can be extended up to 2048
respectively.
In the “FIX” mode, the slots in the left half of the mount
base are for input modules and those in the right half of the
mount base are for output modules. I/O numbers for the
input slots are “X
△△△
” and those for the output slots are
“Y
△△△
.”
In the “FREE” mode, each slot on the mount base is used for
an input module or output module and an I/O number
“X
△△△
” or “Y
△△△
” is assigned to the slot. The I/O
number to be designated must be proper for the I/O module
to be mounted. Further, the module in the slot can be
switched between input and output as the slot can receive
either an input module or an output module.
⑤
Output Hold setting Used to set the output status (RESET or HOLD) of the output
module in case of a line disconnection. When “RESET” is
set, the output module outputs a zero output. When “HOLD”
is set, the output module outputs a value just before the line is
disconnected.
⑥
Terminating
resistance setting
Used to terminate the station module with a built-in terminating
resistor (120 ohms) when the station module is in the end of the
line.
⑦
Special mode
setting terminal
Reserved for future expansion. (Keep this terminal open.)
⑧
Line terminal
Connect the line cable to this terminal.
⑨
Frame ground
Connect the grounding wire to this terminal.
⑩
LED indicator
TX/RX: Lights while transmission is in progress.
ERR : Lights when a hardware error occurs.
