Outline
The outline of the basic module is shown in the following figure by taking the
example of IVC1 L-1614MDR.
PORTO and PORT1, PORT2 are
communication terminals. PORTO uses RS232 mode with Mini DINS socket. PORT1
and PORT2 Have Double RS485. The busbar socket is for connecting the extension
module. The mode selection switch has three positions: ON, TM and OFF.

Power Supply
The specification of PLC built-in power and power for extension modules is
listed in the following table. 
Digital Inputs & Outputs
Input Characteristic And Specification
The input characteristic and specs are shown as follows:
The input terminal act as a counter
has a limit over the maximum frequency. Any frequency higher than that may
result in incorrect counting or abnormal system operation. Make sure that the
input terminal arrangement is reasonable and external sensors used are proper.
Input connection example
The following diagram shows an example of IVC1L-1614MDR in connection with an
IVC1-0808ENR, which realizes simple positioning control. The positioning
signals from the PG are input through high speed counting terminals XO and X1,
the limit switch signals that require high-speed response can be input through
high-speed terminals X2-X7. Other user signals can be input through any other
input terminals.
Output Characteristic And Specification
The following table shows the relay output and transistor output.
The electric specs of outputs is shown in the following table.
Output connection example
The following diagram shows an example of IVC1 L-1614MDR in connection with an
IVC1-0808ENR. Different output groups can be connected to different signal
circuits with different voltages. Some (like YO-COMO) are connected to the
24Vdc circuit powered by local 24V-COM, some (like Y2-COM1) are connected to
the 5Vdc low voltage signal circuit, and others (like Y4-Y7) are connected to
the 220Vac voltage signal circuit.
Communication Port
IVC1 L series PLC basic module has three serial asynchronous communication
ports: PORTO and PORT1, PORT2. Supported baud rates:
115200 bps
9600 bps
57600 bps
4800 bps
38400 bps
2400 bps
19200 bps
1200 bps
The mode selection switch determines the communication protocol.
As a terminal dedicated to user
programming, PORTO can be converted to programming protocol through the mode
selection switch. The relationship between PLC operation status and the
protocol used by PORTO is shown in the following table.
PORT1, PORT2 are ideal for
connection with equipment that can communicate (such as inverters). With
Modbus protocol or RS485 terminal free protocol, ii can control multiple
devices through the network. Its terminals are fixed with screws. You can use
a shielded twisted-pair as the signal cable to connect communication ports by
yourself.
Installation
PLC is applicable to Installation category 11, Pollution degree 2.
Installation Dimensions
Installation Method
DIN rail mounting
Generally you can mount the PLC onto a 35mm-wide rail (DIN), as shown in the
following figure.
Screw fixing
Fixing the PLC with screws can stand greater shock than DIN rail mounting. Use
M3 screws through the mounting holes on PLC enclosure to fix the PLC onto the
backboard of the electric cabinet, as shown in the following figure.

Fix with M3 bolt
Cable Connection And Specification
Connecting power cable and grounding cable The connection of power and
auxiliary power is demonstrated in the following figure. We suggest you wire a
protection circuit at the power supply input terminal. See the figure below.
Connect the PLC @ terminal to the
grounding electrode. To ensure reliable grounding cable connection, which
makes the equipment safer and protects it from EMl.useAWG12 – 16 cable, and
make the cable as short as possible. Use independent grounding. Avoid sharing
route with the grounding cable of other equipment (particularly those with
strong EMI). See the following figure.
Cable specification
When wiring a PLC, use multi-strand copper wire and ready-made insulated
terminals to ensure the quality. The recommended model and the cross-sectional
area of the cable are shown in the following table.
Wire| Cross-sectional area| Recommended model| Cable
lug and heat-shrink tube
---|---|---|---
power cable| 1.0-2.0mm2| AWG12, 18| H1.5/14 round insulated lug, or tinned
cable lug
Earth cable| 2.0mm2| AWG12| H2.0/14 round insulated lug, or tinned cable end
Input signal cable (X)| 0.8-1.0mm2| AWG18, 20| UT1-3 or OT1-3 solderless lug 3
or4 heat shrinkable tube
Output signal cable (Y)| 0.8-1.0mm2| AWG18, 20
Fix the prepared cable head onto the PLC terminals with screws. Fastening
torque: 0.5-0.8Nm.
The recommended cable processing-method is shown in the following figure.
Power-on Operation And Maintenance
Startup
Check the cable connection carefully. Make sure that the PLC is clear of alien objects and the heat dissipation channel is clear.
- Power on the PLC, the PLC POWER indicator should be on.
- Start the Auto Station software on the host and download the compiled user program to the PLC.
- After checking the download program, switch the mode selection switch to the ON position, the RUN indicator should be on. If the ERR indicator is on, the user program or the system is faulty. Loop up in the IV2/IVC1 L series PLC Programming Manual and remove the fault.
- Power on the PLC external system to start system debugging.
Routine Maintenance
Do the following:
- Ensure the PLC a clean environment. Protect it from aliens and dust.
- Keep the ventilation and heat dissipation of PLC in good condition.
- Ensure that the cable connections are reliable and in good condition.
Warning
- Never connect the transistor output to an AC circuit (like 220Vac). The design of the output circuit must abide by the requirements of electric parameters, and no over-voltage or over-current is allowed.
- Use the relay contacts only when necessary, because the life span of relay contacts depends largely on its action times.
- The relay contacts can support loads smaller than 2A. To support larger loads, use external contacts or mid-relay.
- Note that the relay contact may fail to close when the current is smaller than 5mA.
Notice
- The warranty range is confined to the PLC only.
- Warranty period is 18 months, within which period INVT conducts free maintenance and repairing to the PLC that has any fault or damage under the normal operation conditions.
- The start time of warranty period is the delivery date of the product, of which the product SN is the sole basis of judgment. PLC without a product SN shall be regarded as out of warranty.
- Even within 18 months, maintenance will also be charged in the following situations:
- Damages incurred to the PLC due to mis-operations, which are not in compliance with the User Manual;
- Damages incurred to the PLC due to fire, flood, abnormal voltage, etc;
- Damages incurred to the PLC due to the improper use of PLC functions.
- The service fee will be charged according to the actual costs. If there is any contract, the contract prevails.
- Please keep this paper and show this paper to the maintenance unit when the product needs to be repaired.
- If you have any question, please contact the distributor or our company directly.
