3.1 Input characteristics and signal specifications
Table 3-1 describes the input characteristics and signal specifications.
Table 3-1 Input characteristics and signal specifications
(1) The transistor output circuit is equipped with a built-in voltage-stabilizing
tube to prevent the counter-electromotive force caused when the inductive
load is disconnected. If the capacity of the load exceeds the specification
requirement, you need to add an external freewheeling diode.
(2) High-speed transistor output involves distributed capacitance. Therefore, if
the machine runs at 200 kHz, you need to ensure that the conducted current is
larger than 15 mA to improve the output characteristc curve, and the device
connected to it can be connected to a resistor in parallel mode to increase the
load current.
3.3 Input/output connection instances
Input connection instance
The maximum frequency of the high-speed input port is limited. If the input
frequency exceeds the limit, the counting may be incorrect or the system fails
to run properly. You need to select a proper external sensor.
The PLC provides the "S/S" port for selecting the signal input mode. You can
select the source-type or sink-type mode. Connecting "S/S" to "+24V"
indicates that you select the sink-type input mode, and then an NPN-type
sensor can be connected. If "S/S" is not connected to "+24V", it indicates that
the source-type input mode is selected. See Figure 3-1 and Figure 3-2.
Figure 3-3 shows the connection of IVC3-1616MAT and IVC-EH-0808ENR,
which is an instance of implementing simple positioning control. The position
signals obtained by the encoder can be detected by the X0 and X1 high-speed
counting terminals. The position switch signals that require quick response
can be connected to the high-speed terminals X2 to X7. Other user signals
can be distributed among the input terminals.
Output connection instance
Figure 3-4 shows the connection of IVC3-1616MAT and IVC-EH-0808ENR.
The output groups can be connected to different signal voltage circuits, that is,
the output groups can operate in circuits of different voltage classes. They can
be connected only to DC circuits. Pay attention to the direction of the current
when connecting them.

4.1 Serial communication
The IVC3 series main module provides three asynchronous serial
communication ports, namely PORT0, PORT1, and PORT2. They support the
baud rates of 115200, 57600, 38400, 19200, 9600, 4800, 2400, and 1200 bps.
PORT0 adopts the RS232 level and the Mini DIN8 socket. Figure 4-1
describes the pin definition of PORT0.
Use STPs for CAN communication. If multiple devices are involved in
communication, ensure that the GND terminals of all the devices are
connected and the terminal resistors are set to ON.
4.4 Ethernet communication
Table 4-4 Ethernet communication characteristics
Figure 4-1 Position of the mode selection switch and definition of PORT0 pins
As a specialized interface for user programming, PORT0 can be forcibly
switched to the programming port protocol through the mode selection switch.
Table 4-1 describes the mapping between PLC running states and PORT0
running protocols.
Table 4-1 Mapping between PLC running states and PORT0 running protocols
4.2 RS485 communication
Both PORT1 and PORT2 are RS485 ports that can be connected to devices
with communication functions, such as inverters or HMIs. These ports can be
used to control multiple devices in networking mode through the Modbus, N:N,
or free-port protocol. They are terminals fastened with screws. You can make
the communication signal cables by yourself. It is recommended that you use
shielded twisted pairs (STPs) to connect the ports.

5 Installation
IVC3 Series PLCs are applicable to scenarios with installation environments of
standard II and pollution level of 2.
5.1 Dimensions and specifications
Table 5-1 describes the dimensions and specifications of IVC3 series main
modules.
Table 5-1 Dimensions and specifications
5.2 Installation modes
Using DIN slots
4.3 CANopen communication
Table 4-3 CAN communication characteristics
Generally, the PLCs are installed by using DIN slots with a width of 35 mm, as
shown in Figure 5-1.
Figure 5-1 Diagram of installation by using a DIN slot
The specific installation steps are as follows:
1. Fix the DIN slot horizontally on the installation backplate.
2. Pull out the DIN slot clamping buckle from the bottom of the module.
3. Mount the module onto the DIN slot.
4. Press the clamping buckle back to where it was to lock the fix the module.
5. Use the stoppers of the DIN slot to fix the two ends of the module,
preventing it from sliding.
These steps can also be used to install other PLCs of the IVC3 series by using
DIN slots.
Using screws
For scenarios where large impact may occur, you can install the PLCs by
using screws. Put the fastening screws (M3) through the two screw holes on
the housing of the PLC and fix them on the backplate of the electrical cabinet,
as shown in Figure 5-2.

Power cable and grounding cable connection
Figure 5-3 shows the connection of the AC and auxiliary power supplies.
The anti-electromagnetic interference capability of the PLCs can be improved
by configuring reliable grounding cables. When installing a PLC, connect the
power supply terminal
connection wires of
to the ground. It is recommended that you use
AWG12 to AWG16 and try to shorten the wires, and that you
configure independent grounding and keep the grounding cables away from those of
other devices (especially those generating strong interference), as shown in Figure
5-4.
Cable specifications
For the wiring of the PLC, it is recommended that you use multi-stranded
copper wire and prepare insulated terminals to ensure the wiring quality. Table
5-2 describes the recommended wire cross-sectional areas and models.
Fix the processed cable terminals onto the wiring terminals of the PLC by
using screws. Pay attention to the positions of the screws. The tightening
torque for the screws is 0.5 to 0.8 Nm, which can be used to complete reliable
connection without damaging the screws.
Figure 5-5 shows the recommended cable preparation mode.
Table 5-2 Recommended cross-sectional areas and models
Do not connect transistor output to AC circuits, such as a circuit of 220 V AC.
Strictly follow the electrical parameters to design the output circuits. Ensure
that no overvoltage or overcurrent occurs.
6 Power-on, operation, and routine
maintenance
6.1 Power-on and operation
After the wiring is complete, check all the connections. Ensure that no foreign
matters have dropped inside the housing and heat dissipation is in good
conditions.
1. Power on the PLC.
The POWER indicator of the PLC is on.
2. Start the Auto Station software on the PC and download the compiled user
program to the PLC.
3. After the program is downloaded and verified, set the mode selection
switch to ON.
The RUN indicator is on. If the ERR indicator is on, it indicates that errors
occur on the user program or the system. In this case, rectify the errors by
referring to the instructions in the IVC Series Small-sized PLC
Programming Manual.
4. Power on the PLC external system to perform commissioning on the
system.
6.2 Routine maintenance
Pay attention to the following aspects when performing routine maintenance
and inspection:
1. Ensure that the PLC operates in a clean environment, preventing foreign
matters or dust from dropping into the machine.
2. Keep the PLC in good ventilation and heat dissipation conditions.
3. Ensure that the wiring is properly performed and all the wiring terminals
are well fastened.
