SAFETY PRECAUTIONS
(Read these precautions before using this product.)
Before using this product, please read this manual and the relevant manuals carefully and pay full attention
to safety to handle the product correctly.
The precautions given in this manual are concerned with this product only. For the safety precautions of the
programmable controller system, refer to the user's manual for the CPU module used.
In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION".
Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to
serious consequences.
Observe the precautions of both levels because they are important for personal and system safety.
Make sure that the end users read this manual and then keep the manual in a safe place for future
reference.
[Design Precautions]
[Design Precautions]
WARNING
●An AnyWire Bitty system has no control function for ensuring safety.
●When a communication failure occurs in the network, data in the master module are held. Check the
communication status information and configure an interlock circuit in the sequence program to
ensure that the entire system will operate safely.
CAUTION
●Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.
●Configure safety circuits, such as an emergency stop circuit and interlock circuit, external to the
AnyWire Bitty system.
WARNING
CAUTION
Indicates that incorrect handling may cause hazardous conditions,
resulting in death or severe injury.
Indicates that incorrect handling may cause hazardous conditions,
resulting in minor or moderate injury or property damage.

[Installation Precautions]
[Wiring Precautions]
CAUTION
●Use the module in an environment that meets the general specifications in this manual. Failure to do
so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.
●Securely fix the module with a DIN rail.
●Do not directly touch any conductive parts and electronic components of the module. Doing so can
cause malfunction or failure of the module.
CAUTION
●Shut off the external power supply (all phases) used in the system before wiring. Failure to do so may
cause the module to fail or malfunction.
●Individually ground the FG and LG terminals of the programmable controller with a ground resistance
of 100 ohms or less. Failure to do so may result in electric shock or malfunction.
●Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly. Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire
or failure.
●Tighten the terminal screw within the specified torque range. Undertightening can cause short circuit
or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit,
or malfunction.
●Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can
cause a fire, failure, or malfunction.
●Incorrect wiring may damage modules and external devices. Adjust a cable length and a module
position to prevent disconnection of a connector type terminal block or a cable.
●Do not solder stranded wires of a cable when connecting them to the terminal block. Doing so may
cause poor contact.
●The power supply voltage of remote slave modules may be insufficient due to a voltage drop in the
power supply line. Connect an external power supply so that the voltage of remote slave modules is
ensured.
●Do not apply the 24VDC power before wiring the entire AnyWire Bitty system. If the power is applied
before wiring, normal data transmission is not guaranteed.
●Use 24VDC stabilized power supplies for devices in the AnyWire Bitty system.
●Do not install the control lines or communication cables together with the main circuit lines or power
cables. Failure to do so may result in malfunction due to noise.
●Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled,
resulting in damage to the module or cables or malfunction due to poor contact.
●When disconnecting the cable from the module, do not pull the cable by the cable part. When
disconnecting a cable connected to a terminal block, loosen the screws on the terminal block first
before removing the cable. If a cable is pulled while being connected to the module, it may cause the
module to malfunction or damage the module and the cable.

[Startup and Maintenance Precautions]
[Startup and Maintenance Precautions]
[Disposal Precautions]
WARNING
●Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.
●Shut off the external power supply (all phases) used in the system before cleaning the module or
retightening the terminal screws or module fixing screws. Failure to do so may result in electric shock.
Undertightening the terminal screws can cause short circuit or malfunction. Overtightening can
damage the screw and/or module, resulting in drop, short circuit, or malfunction.
CAUTION
●Do not disassemble or modify the modules. Doing so may cause failure, malfunction, injury, or a fire.
●Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may cause the module to fail or malfunction.
●Before handling the module, touch a grounded metal object to discharge the static electricity from the
human body. Failure to do so may cause the module to fail or malfunction.
CAUTION
●When disposing of this product, treat it as industrial waste.

2.2 Performance Specifications 2.2.1 Performance specifications
*1 Ver.1.10- compatible CC-Link dedicated cable, CC-Link dedicated cable (Ver.1.00), and high-performance CC-Link
dedicated cable cannot be used at the same time. If those cables are used at the same time, normal transmission is not
guaranteed. In addition, use the terminating resistor according to the type of cable used.
*2 Refer to the table below for the relationship between the total length, the diameter of transmission cable (DP, DN), and
the transmission cable supply current.
When a total length exceeds 50m, use isolated slave modules. For some slave modules with cables, the wire diameter
of module-integrated transmission cable (DP, DN) may be 0.75or less. However, they can be used without any
problem, provided that the diameter of transmission cable (DP, DN) meets the following requirements.

2.2.2 Scope of the power supply for the transmission cable
To implement the AnyWire Bitty system, all conditions specified by the following calculation formulas 1) to 3) have to
be met.
(1) Description of calculation formula 1)
(a) Related constant of non-isolated slave modules (Ihin, Iho)
For non-isolated slave modules, current required for the internal control circuit and connected load is supplied
through the transmission cable (DP, DN).
Ihin(A)
= Current consumption of non-isolated input slave module/I/O combined slave module
= Current consumption of non-isolated input slave module/I/O combined slave module + Current consumption
of connected load (three-wire sensor) Number of points
Iho(A)
= Current consumption of non-isolated output slave module
= Current consumption of non-isolated output slave module + Current consumption of connected load 
Number of points
●The 24VL and 0VL terminals of a slave module are used to supply the power to the connected load. For details, refer to
the manual for the slave module used.
●For the current consumption of non-isolated slave modules, refer to the manual for the slave module used.

(b) Related constant of isolated slave modules (Izdin, Izdo)
For isolated slave modules, only the current required for the internal control circuit is supplied through the
transmission cable (DP, DN), whereas that for the connected load is supplied from a 24VDC external power
supply.
Izdin(A) = Internal current consumption of isolated input slave module/I/O combined slave module
Izdo(A) = Internal current consumption of isolated output slave module
●In isolated slave modules, current consumption of the connected load is not subject to the current restriction condition for
the AnyWire Bitty system.
●For the current consumption of isolated slave modules, refer to the manual for the slave module used.
(c) Supply current for transmission cable (I (A))
The supply current for the transmission cable of the AnyWire Bitty system is determined by the following
formula.
I(A) = (Ihin m) + (Iho n) + (Izdin p) + (Izdo q)
Number of connectable modules: m, n, p, q
(d) Maximum value of transmission cable supply current
For the maximum value of transmission cable supply current, refer to the following.
