The outline of the basic module is shown in the following figure by taking the example of IVC1L-1614MAR.
PORTO and PORT1. PORT2 are communication terminals. PORTO uses RS232 mode with Mini DIN8 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.
The layouts of terminals of different I/O points are shown below:
14-point, 16-point, 24-point
The specification of PLC built-in power and power for extension modules is sted in the following table.

The sum of input frequency should be less than 60kHz
|Common terminal||Only one common terminal: COM|
The input terminal act as a counter has a limit over the maximum frequency. Any frequency highe 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-1614MAR 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 connection example
The following diagram shows an example of IVC1L-1614MAR 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 114-117) are connected to the 220Vac voltage signal circuit.
IVC1L series PLC basic module has three serial asynchronous communication ports: PORTO, PORT1, and PORT2. 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.
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|
|Converted to programming protocol|
|OFF||Stop||If the system configuration of user program is free-port protocol, it converts to programming protocol automatically after stop; or system protocol keeps unchanged|
PORT1 PORT2 are 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.
PLC is applicable to Installation category II, Pollution degree 2.

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
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.
|Cable lug and |
|AC power |

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.
Check the cable connection carefully. Make sure that the PLC is clear of alien objects and the heat dissipation channel is clear.
