Output connection example
The following diagram shows an example of VC1-1614MAR in connection with an VC-
0808ENR. Different output groups can be connected to different signal circuits with different
voltages. Some (like Y1-COM0) are connected to the 24Vdc circuit powered by local 24V-
COM, some (like Y5-COM1) are connected to the 5Vdc low voltage signal circuit, and others
(such as Y11, Y13, Y15) are connected to the 220Vac voltage signal circuit.

4Communication port
VC1 series PLC module has 2 serial asynchrounous communication ports: COM0 and COM1.
Supported baud rates: 115200, 57600, 38400, 19200, 9600, 4800, 2400, 1200bps. The mode
selection switch determines the communication protocol of COM0. As shown in below figure:

As a dedicated interface to user programming, COM0 can be converted to programming
protocol through the mode selection switch. The relationship between PLC operation status
and the protocol used by COM0 is shown in the following table.
Mode selection switch
position
Programming protocol, or Modbus protocol as determined by
user program and system configuration
If the system configuration of user program is Modbus protocol,
it converts to programming protocol automatically after stop.
Otherwise, the system protocol keeps unchanged
COM1 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.
USB is Type-C interface, it can support upload, download, on line upgrade firmware and
monitoring function.
5Installation
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.

The specific installation steps are as follows:
1．Fix the DIN rail horizontally on the mounting backplane.
2．Pull out the DIN rail buckle under the bottom of the module.
3．Hang the module on the DIN.
4．Press the buckle back to its original position to lock the module.
5．Finally, fixed both ends of the module with DIN rail clips to avoid sliding.
Other VC1 series PLC can be installed in DIN rail according to the above steps.
Use scews to install and fix
For occasions with large oscillations, the main module can be installed with screw holes.
When installing the expansion module, first slide the sliding lock up to the top, align it and
push it toward the main module, and then slide the sliding lock down to the end to complete
the fixation. As shown below. (Note: The main module requires optional accessories for screw
installation, and the expansion module does not support screw installation)
