Communication and Removable Memory Storage

When products comprise either USB communication port, SD card slot, or both, neither
the SD card slot nor the USB port are intended to be permanently connected, while the USB port is intended for programming only.

Removing / Replacing the battery

When a product has been installed with a battery, do not remove or replace the battery unless the power has been switched off, or the area is known to be non-hazardous. Please note that it is recommended to back up all data retained in RAM, in order to avoid losing data when changing the battery while the power is switched off. Date and time information will also need to be reset after the procedure.

Wiring

• Do not touch live wires.
• Install an external circuit breaker. Guard against short-circuiting in external wiring.
• Use appropriate circuit protection devices.
• Unused pins should not be connected. Ignoring this directive may damage the device.
• Double-check all wiring before turning on the power supply.

Caution

• To avoid damaging the wire, do not exceed a maximum torque of 0.5 N·m (5 kgf·cm).
• Do not use tin, solder, or any substance on stripped wire that might cause the wire strand to break.
• Install at maximum distance from high-voltage cables and power equipment.

Input Jumper Settings

The tables below show how to set a specific jumper to change input functionality. To access the I/O jumpers, you must open the controller according to the instructions beginning on page 13.

• Incompatible jumper settings and wiring connections may seriously damage the controller.

• Shields should be connected at the signal’s source.
• The 0V signal of the analog input must be connected to the controller’s 0V.
• Thermocouple 0: use Input 9 as negative input and 10 as positive.
• Thermocouple 1: use Input 7 as negative input and 8 as positive.

RTD

• PT100 (Sensor 0): use Input 9 and 10, related to CM signal.
• PT100 (Sensor 1): use Input 7 and 8, related to CM signal.
• 4 wire PT100 can be used by leaving one of the sensor leads unconnected.

Relay Outputs 

Increasing Contact Life Span
To increase the life span of the relay output contacts and protect the device from potential damage by reverse EMF, connect:

• A clamping diode in parallel with each inductive DC load
• An RC snubber circuit in parallel with each inductive AC load

Power Supply 

The controller requires an external 24VDC power supply.

• The power supply must include double insulation. Outputs must be rated as SELV/PELV/Class2/Limited Power.
• Use separate wires to connect the functional earth line (pin 3) and the 0V line (pin 2) to the system earth ground.
• Install an external circuit breaker. Guard against short-circuiting in external wiring.
• Double-check all wiring before turning on the power supply.
• Do not connect either the ‘Neutral’ or ‘Line’ signal of the 110/220VAC to device’s 0V pin
• In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the device to a regulated power supply.

Earthing the PLC+HMI
To maximize system performance, avoid electromagnetic interference by:

• Mounting the controller on a metal panel.
• Connect each common and ground connection directly to the earth ground of your system.
• For ground wiring uses the shortest and thickest possible wire.

Communication

• V130/ V130J/V350J
  These models comprise a built-in RS232/RS485 serial port (Port 1)
• V430J/ V350/V350J
  These models comprise built-in ports: 1 USB and 1 RS232/RS485 (Port 1).

Note that physically connecting a PC to the controller via USB suspends RS232/RS485 communications via Port 1. When the PC is disconnected, RS232/RS485 resumes.

RS232/RS485 Port

• 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.

Pinouts
The pinouts below show the PLC port signals.* 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.
Note that it is possible to establish a PC to PLC connection using RS232 even when the PLC is set to RS485 (this eliminates the need to open the controller to set jumpers).
To do so, remove the RS485 connector (pins 1 & 6) from the PLC and connect a standard RS232 programming cable.
Note that this is possible only if DTR and DSR signals of RS232 are not used (which is the standard case).

Setting RS232/RS485 Communication Parameters, V130/V350/V130J/V350JThis port may be set to either RS232 or RS485 via jumper.
The accompanying figure shows the jumper factory default settings.
These jumpers may be used to:

• Set communications to RS485, by setting both COMM jumpers to ‘485’.
• Set RS485 termination, by setting both TERM jumpers to ‘OFF’.

To access the jumpers, you must open the controller according to the instructions on page 13.

Setting RS232/RS485 Communication Parameters, V430J
This port may be set to either RS232 or RS485 via DIP switches:
The table shows the DIP switches factory default settings. Use the table to adapt the settings.

USB Port

Opening the Controller

• Before performing these actions, touch a grounded object to discharge any electrostatic charge.
• Avoid touching the PCB board directly. Hold the PCB board by its connectors.

1. Turn off the power supply, disconnect, and dismount the controller.
2. The back cover of the controller comprises 4 screws, located in the corners. Remove the screws, and pull off the back cover.

Changing I/O Settings
After opening the controller and exposing the I/O board, you can change the jumper settings according to the table shown above.

Changing Communication Settings (V130/V350/V130J/V350J Only)

1. To access the communication jumpers, hold the I/O PCB board by its top and bottom connectors and steadily pull the board off.
2. Locate the jumpers, and then change the settings as required, according to the jumpers’ settings shown on page 12.

Closing the Controller 

1. Gently replace the board. Make certain that the pins fit correctly into their matching receptacle. Do not force the board into place; doing so may damage the controller.
2. Replace the back cover of the controller and fasten the corner screws.

Note that you must replace the back cover securely before powering up the controller.

Technical Specifications

Order Information

High Speed Input
Up to 50 meters, shielded, see Frequency table below

Conversion times are accumulative and depend on the total number of analog inputs configured. For example, if only one analog input (fast mode) is configured, the conversion time will be 30ms; however, if two analog (normal mode) and two RTD inputs are configured, the conversion time will be 100ms + 100ms + 300ms + 300ms = 800ms.
The analog value can indicate faults as shown below:

Notes:
The analog value can indicate faults as shown below:

• Value
  Possible Cause
• 32767
  Sensor is not connected to input, or value exceeds permissible range
• -32767
  Sensor is short-circuited

Notes:
The device can also measure voltage within the range of -5 to 56mV, at a resolution of 0.01mV. The device can also measure raw value frequency at a resolution of 14-bits (16384). Input ranges are shown in the following table:
