Output connection example
The following diagram shows an example of IVC1S-1614MAR. 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
IVC1S series PLC basic module has three serial asynchronous communication ports: PORTO and PORT1. Supported baud rates:
| 115200 bps | 57600 bps | 38400 bps | 19200 bps |
| 9600 bps | 4800 bps | 2400 bps | 1200 bps |
The mode selection switch determines the communication protocol.
| Pin No. | Name | Description |
| 3 | GND | Ground |
| 4 | RXD | Serial data receiving pin (from RS232 to PLC) |
| 5 | TXD | Serial data transmitting pin (from PLC to RS232) |
| 1, 2, 6, 7, 8 | Reserved | Undefined pin, leave it suspended |
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.
| Mode selection switch position | status | PORTO operation protocol |
| ON | Running | Programming protocol, or Modbus protocol, or free-port protocol, or N: N network protocol, as determined by user program and system configuration |
| OFF | Stop | Converted to programming protocol |
PORT1 is ideal for connection with equipment that can communicate (such as inverters). With Modbus protocol or RS485 terminal free protocol, it 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 II, Pollution degree 2.

5.2 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.
5.3. Cable Connection And Specification
Connecting power cable and grounding cable
The connection of AC 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 EMI. use AWG12 – 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 |
| AC power cable (L, N) | 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 Φ3 or Φ4 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
6.1 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 [V2/IVC1S series PLC Programming Manual and remove the fault.
- Power on the PLC external system to start system debugging.
6.2 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.
