Setting Method

9.1 Setting of CC-Link station number and transmission rate

When connecting this unit to the CC-Link transmission line, set a unique station number (STATION) for the unit before applying power to the
unit, and set the transmission rate (B RATE). A unit provided with the CC-Link communication function communicates mutually with another
unit at the transmission rate that has been set by using the station number. Set the station number and communication rate without fail.
To set the station number, change the setting of the station number setting switch (
To set the transmission rate, change the setting of the B RATE setting switch (
1
Set the station number (STATION).
This unit is a remote device station that occupies one station.
The station number setting range is from 1 to 64.
The station number is the sum of the values of the station number setting switch toggles that are set to ON.
To turn on the station number setting switch toggles, use a thin screwdriver or bar.
When setting the station number of this unit to 36, set the switch as shown below.
⋅ Turn on the switch toggles 1 and 2 on the ×10 side of the station number setting switch and the switch toggles 2 and 4 on the ×1 side
(The arrow => indicates the ON position.)
×10 (tens place) = (1+2) × 10 = 30
×1 (unit's place) = (2+4) × 1 = 6
2
Set the transmission rate (B RATE).
To set the B RATE setting switch, use a thin slotted screwdriver.
The relationship between the transmission rate and the setting switch is shown below.

* If the switch is set to a state not shown above, an error occurs.

If the station number and/or the transmission rate are/is set or changed after power is applied to the unit, press the reset switch.
If the reset switch is not pressed, the setting(s) will be made ineffective.
It takes some seconds until the settings are reset. Keep pressing the reset switch, and release the switch after ensuring that RUN LED
is turned off.
Do not use a mechanical pencil to change the setting of the station number switch or the transmission rate switch.
Caution
Broken leads and lead powders may be scattered on the internal circuit, thereby causing malfunction or failure.
The station-to-station cable length and the maximum total cable extension distance vary depending on the
transmission rate.
Take care that a station number is not duplicated in a transmission route. If a number is duplicated, an error occurs.
The number of units that meets the following conditions 1 and 2 can be connected on CC-Link. When only energy measuring units are
connected, up to 42 units can be connected.
Condition 1: {(1 × a)+(2 × b)+(3 × c) + (4 × d)} ≤64
a: Number of units occupying one station
c: Number of units occupying three stations
Condition 2: {(16 × A)+(54 × B)+(88 × C)} ≤2304
A: Number of remote I/O station, B: Number of remote device stations, C: Number of local stations
30 + 6 = 36 ... Station No. 36
Set the toggles 1 and 2 to ON.
Set the toggles 2 and 4 to ON.
