Filtering

filtering| X0—X7: The filtering time can be set through programming, and the allowable range is 0 to 60 ms.
Hardware
filtering| Hardware filtering is adopted for ports except the XO to X7, and the filtering time is about 10 ms.
High-speed function| Ports XO to X7 can implement multiple functions including high-speed counting, interrupting, and pulse capture.
The maximum touting frequency of XO to X7 is 200 kHz.

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.

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
Figure 3-3 shows the connection of IVC3-1616MAT and IVC-EH-O808ENR, which is an instance of implementing simple positioning control. The position signals obtained by the encoder can be detected by the XO 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-O808ENR. 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.

Communication guide

4.1 Serial communication
The IVC3 series main module provides three asynchronous serial communication ports, namely PORTO, PORT1, and PORT2. They support the baud rates of 115200, 57600, 38400, 19200, 9600, 4800, 2400, and 1200 bps. PORTO adopts the RS232 level and the Mini DIN8 socket. Figure 4-1 describes the pin definition of PORTO.

Figure 4-1 Position of the mode selection switch and definition of PORTO pins
As a specialized interface for user programming, PORTO 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 PORTO running protocols.
Table 4-1 Mapping between PLC running states and PORTO running protocols

be the programming port, Modbus, free-port, or N:N network protocol.
TM (ON→TM)| Running| Forcibly switched to the programming port protocol.
TM (OFF→TM)| Stopped
OFF| Stopped| If the free-port protocol is used in the system configuration of the user program, PORTO is automatically switched to the programming port protocol after the PLC is stopped. Otherwise, the protocol set in the system is not switched.

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.

Installation

IVC3 Series PLCs are applicable to scenarios with installation environments of standard Il 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

IVC3-1616MAR

5.2 Installation modes
Using DIN slots
Generally, the PLCs are installed by using DIN slots with a width of 35 mm, as shown in Figure 5-1.

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.

5.3 Cable connection and specifications
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 **** to the ground. It is recommended that you use connection wires of 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.

Table 5-2 Recommended cross-sectional areas and models

Cable| Coss-sectional area of wire| Recommended wire model| Cmpatible wiring terminals and heat-shrinkable tubing
---|---|---|---
AC power, N)
cable (L| 1 .0-2.0mm2| AWG12, 18| H1.5/14 preinsulated tube-like terminal, or hot tin-coated cable terminal
Grounding cable ****| 2•Omm2| AWG12| H2.0/14 preinsulated tube-like terminal, or hot tin-coated cable terminal
Input signal
cable (X)| 0.8-1.0mm2| AWG18, 20| UT1-3 or OT1-3 cold-pressed terminal, 03 or (D4 heat-shrinkable tubing
Output signal cable (Y)| 0.8-1.0mm2| AWG18, 20

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.

Waming
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.

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 /VC 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.
