Wiring Procedure
Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm 2–3.31 mm2 ).
- Strip the wire to a length of 7±0.5mm (0.250–0.300 inches).
- Unscrew the terminal to its widest position before inserting a wire.
- Insert the wire completely into the terminal to ensure a proper connection.
- Tighten enough to keep the wire from pulling free.
Power Supply
V570-57-T20B & V570-57-T20B-J requires either an external 12 or 24VDC power supply.
Permissible input voltage range: 10.2-28.8VDC, with less than 10% ripple.
|
|
|
|
Earthing the Power Supply
To maximize system performance, avoid electromagnetic interference by:
- Mounting the controller on a metal panel.
- Earthing the controller’s power supply: connect one end of a 14 AWG wire to the chassis signal; connect the other end to the panel.
Note: If possible, the wire used to earth the power supply should not exceed 10 cm in length.
However, it is recommended to earth the controller in all cases.
Communication Ports
This series comprises a USB port, 2 RS232/RS485 serial ports and a CANbus port
|
|
| Caution |
|
The USB port may be used for programming, OS download, and PC access.
Note that COM port 1 function is suspended when this port is physically connected to a PC.
The serial ports are type RJ-11 and may be set to either RS232 or RS485 via DIP switches, in accordance with the table shown below.
Use RS232 to download programs from a PC, and to communicate with serial devices and applications, such as SCADA.
Use RS485 to create a multi-drop network containing up to 32 devices.
The pinouts below show PLC port signals.
To connect a PC to a port that is set to RS485, remove the RS485 connector, and connect the PC to the PLC via the programming cable. Note that this is possible only if flow control signals are not used (which is the standard case).

*Standard programming cables do not provide connection points for pins 1 and 6.
**When a port is adapted to RS485, Pin 1 (DTR) is used for signal A, and Pin 6 (DSR) signal is used for signal B.
RS232 to RS485: Changing DIP Switch Settings
The ports are set to RS232 by factory default.
To change the settings, first remove the Snap-in I/O Module, if one is installed, and then set the switches according to the following table.
RS232/RS485: DIP Switch Settings
The settings below are for each COM port.

**Causes the unit to function as an end unit in an RS485 network
Removing a Snap-in I/O Module
- Locate the four buttons on the sides of the controller, two on either side.
- Press the buttons and hold them down to open the locking mechanism.
- Gently rock the module from side to side, easing the module from the controller
Re-installing a Snap-in I/O Module
- Line the circular guidelines on the controller up with the guidelines on the Snap-in I/O Module as shown below.
- Apply even pressure on all 4 corners until you hear a distinct ‘click’. The module is now installed.
Check that all sides and corners are correctly aligned.
CANbus
These controllers comprise a CANbus port. Use this to create a decentralized control network using one of the following CAN protocols:
- CANopen: 127 controllers or external devices
- CANLayer 2
- Unitronics’ proprietary UniCAN: 60 controllers, (512 data bytes per scan)
The CANbus port is galvanically isolated.
CANbus Wiring
Use twisted-pair cable. DeviceNet® thick shielded twisted pair cable is recommended.
Network terminators: These are supplied with the controller. Place terminators at each end of the CANbus network.
Resistance must be set to 1%, 121Ω, 1/4W.
Connect ground signal to the earth at only one point, near the power supply.
- The network power supply need not be at the end of the network.
