Lot No. 19ECBNB
As a result of the addition of functions, indication of lot No. has been changed from 3 digits (conventional format:
year and month only) to 6 digits or 7 digits.
The master unit compatible with the word transmission function provides areas for transmission and receiving of word
data (numerical information) such as analog data and sensing level data.
Using this function enables reduction of occupancy of bit information area by word data.
To enable word transmission, it is necessary that the system should be congured only with slave units compatible with
the word transmission function.
A slave unit incompatible with the word transmission function cannot be connected to the AnyWireASLINK system to
conduct word transmission.
For slave units that handle word data, word address settings are required.

NEW
Function version:
When an equipment parameter is changed due to functional upgrading, etc., the function
version will be updated (for example: A→B→C).
When a slave unit of a new function version is replaced with that of an old function version,
the single unit simplied replacement function cannot be used.
[About Single Unit Simplified Replacement]
During replacement of a slave unit, this function enables automatic settings of address and parameters of the existing
slave unit into a new slave unit. (After replacement of the slave unit, address and parameter setting procedure using the
address writer is not required.)
■Step 1 Turn OFF the 24V DC power supply for the master unit.
■Step 2 Disconnect a slave unit to be replaced.
■Step 3 Connect a new slave unit.
■Step 4 Turn ON the 24V DC power supply to the master unit.
- It is necessary that both the master unit and slave unit should be compatible with the single unit simplied replacement function.
- Before disconnection and connection of the slave unit, be sure to turn OFF the power supply.
- For compatibility of a slave unit with the single unit simplied replacement function, see the lot No. and the manual for the slave unit.
- When a slave unit of a new function version is replaced with that of an old function version, the single unit simplied replacement
function cannot be used.
- Operation is enabled in the case where the model of the slave unit before replacement is the same as that after replacement.
- If the model of the slave unit before replacement is different from that after replacement, a model mismatching error occurs, disabling
address and parameter settings.
- Operation is enabled in the case where the address of the slave unit for replacement is the factory-set address (bit address 511).
- Several slave units cannot be simultaneously replaced. For replacement of several slave units, conduct the replacement procedure for
each unit one by one.
- For a slave unit incompatible with the single unit simplied replacement function, set an address and parameters by using the address
writer as in the conventional manner.
- For details of the single unit simplied replacement function (limitations, conditions, etc.), refer to the manual for the master unit.

[Installation Location]
- Locations where this product is not directly subject to vibration or shock
- Locations where this product is not directly exposed to dust
- Locations where this product is not directly exposed to conductors,
such as metal chips or spatters
- Locations without condensation
- Locations where the atmosphere is free of corrosive gases, ammable
gases, and sulfur
- Locations far from high-voltage or high-current cables
- Locations far from servos, inverters, and other cables and controllers
that generate high-frequency noise
The AnyWireASLINK can employ a two-wire or four-wire terminal selectively depending on the load current.
If the load current is small, using a two-wire (non-isolated) terminal allows for achieving simplied wiring without local power supply.
In the case of prioritizing the sites of concentrated loads and/or the number of connections, hybridization with a four-wire (isolated)
terminal, which supports local power supply, is also possible.
Make sure to use a four-wire (isolated) terminal in the case of input and load driving using an external power supply.
[How to Connect AnyWireASLINK]
AnyWireASLINK terminator
CAUTION
- Refer to Table 1 so that the size and length of the transmission
line and the allowable supply current lie within an appropriate
range.
- Connect the same symbols (DP, DN) correctly between the
AnyWireASLINK master unit and each device.
- The branching length or branch number has no limitation.
- Include the length of the cable provided with the terminal in the
“total line length.”
- Connect the terminator (with polarity) to the terminal farthest
from the AnyWireASLINK master unit.
To connect loads (e.g. I/O ports) that are
controlled with a power supply other than the
one used for the AnyWireASLINK system,
always use a 4-wire (isolated) terminal.
Otherwise, malfunction may be caused.

If the total length of the sections where all the DP, DN, 24V, and 0V lines run in parallel in the power supply system is more than 50m, connect an
ASLINK lter (Type ANF-01) or a lter manufactured by COSEL Co., Ltd. (Type EAC-06-472) in series to the 24V and 0V lines at a position where
these four lines start running in parallel.
This will improve noise resistance, suppress the adverse effects of crosstalk caused by transmitted signals, and stabilize signals.
The above lters must be inserted regardless of whether power is supplied to all terminals collectively from the power supply for the master or
power is supplied to each terminal individually from their local power supply.
Insert the “ASLINK lter [Type ANF-01]” regardless of installation method and distance when complying with CE Standard.

- Set the address number so that the area occupied by the terminal does not exceed the transmission points of the master unit.
- Make sure that the address number setting is not duplicated.
- Also, use the address writer to read an address number that has been written in the terminal.
The factory-set address is “bit address 255” or “bit address 511,” which indicates that an address
has not been set.
The factory-set address varies depending on lot No., as follows:
For S/W version “B” or later version: Bit address 511
For S/W version “A” or 3-digit lot No.: Bit address 255
Input and output operations are disabled with the factory-set address.

Check conditions of the master unit
and slave unit.
Disconnect this unit once, and then reconnect it.
[Troubleshooting]
Things to be checked
Remedy
Things to be checked
Remedy Things to be checked
Remedy Things to be checked
Remedy Things to be checked
1) If LINK on the master unit is ashing and LINK on the slave unit is lit, it is possible that the master
unit has a fault or power supply (24V-0V) is directly connected to the DP-DN pins of the slave unit.
*
If LINK is lit while ALM is ashing, it means a failure in single unit simplied replacement.
2) If LINK on the master unit is ashing and LINK on the slave unit is unlit, it is possible that the power
(24V DC) is not supplied to the master unit, there is a disconnection on the transmission line (DP,
DN), or the slave unit has been damaged.
3) If LINK on the master unit is not ashing, check the power supply to the master unit. Also, since there
is a possibility that some system error has occurred, refer to the user’s manual of the master unit.
4) A slave unit incompatible with Ver.1.1 cannot be used in connection to the AnyWireASLINK system
for word transmission. Check the setting of the master unit, and lot No. of the slave unit.
＜ALM is lit＞
＜ALM is ashing＞
＜LINK and ALM ashes alternately＞
＜LINK is lit and ALM is ashing: Model mismatching error (Failure in single unit simplied replacement)＞
Check the connection of I/O terminals
on the slave unit.
When IN ashes in synchronization with LINK while ALM is lit, the unit has I/O disconnection.
If only ALM is lit, the unit has I/O short-circuit or I/O voltage drop.
1) Make sure that the slave unit I/O line and load are normally connected. Use caution about
disconnection of the wiring and insufcient screw tightening.
2) To connect a mechanical contact (relay, switch, etc.) as load, OFF signal cannot be differentiated
from disconnection. In this case, set the equipment parameter for the disconnection detecting
function to OFF.
3) Check wiring of the slave unit terminals to ensure that the connected load meets the power supply
and output specications of ASLINER, and adjust it as required.
4) Adjust the power supply voltage of an external power source connected to the slave unit I/O line, so
that the power supply voltage does not exceed the rated voltage range (21.6V to 27.6V). Make sure
that wires of the transmission line do not touch each other. Check for incorrect wiring of the terminals.
Adjust the voltage of external power supply to the master unit so that it will be in the range from 21.6 to
27.6V. (Recommended voltage is 26.4V.) Check the total length.
Review the total length and wire diameter of transmission line so that the load will not exceed the current
limit supplied by the transmission line and adjust the connected load. (In the case of the wire size of
1.25mm2and total length of 50m or less, the current supplied by the transmission line is 2A.)
*
If ALM is ashing while LINK is lit, it means a failure in single unit simplied replacement.
Check if the replacement slave unit is of the same type as that of the slave unit before the replacement.
Check if the function version for the replacement slave unit is older than that of the slave unit before the
replacement.
*
If the function version of the replacement slave unit is older, the single unit simplied replacement
function does not work.
The address of the slave unit is either unregistered or duplicated.
Take the following actions.
*
The slave unit cannot be used with the factory-set address.
1) Set a bit address correctly in a range of 0 to 254.
2) Check if there is a slave unit on which the indicator lamps are ashing in the same manner and reset
the addresses so that they are not duplicated.
Check the address of the slave unit.
Check the address of the slave unit.
Check the model of the slave unit.
Check the lot No. of the slave unit.
Check the connection of the slave
unit.
Check the voltage (24V DC) of
external power supply to the master
unit.
Check if the address of the replacement slave unit is the same as the address before shipment (a bit
address of 511).
*
If the address of the replacement slave unit is not the same as the address before shipment, the single
unit simplied replacement function does not work.
Defective connections and the like may have caused single unit simplied replacement to fail.
Remove the slave unit after replacement, and make connections again.
*
When two or more replacement slave units are simultaneously connected, the single unit simplied
replacement function does not work.
