LAN connection type IO controller


● LAN interface: 10Base-T/100Base-TX.
● One to Multiple TCP connection.
● With an input unit (LA-5P-P(G)), it can built an input-output system without using a PC.
● 2 types of power supply (AC adapter is an option)
● Various options (DIN-rail mounting plate. Magnets etc.)

LA-5R(G) is a compact digital IO unit with 5 relay outputs.

Diference of LA-5R(G) and LA-5R are (only G-type supports following):
- Not using an electrolytic condenser.
- Multiple TCP connection. (max.4 units)

■ Useful features for installation in multiple locations, trial operation, and maintenance work

The input/output status can be checked with the LEDs on the surface of the case, making it easy to check the operation during the introduction test.

In addition, a detachable terminal block is used so that the main unit can be replaced without disconnecting the device from the controlled target. It greatly reduces maintenance work time.

The LANIOset is useful when installing LANIOs of the same model in multiple locations.

[ Batch save settings ]

You can save the setting information (setup record) such as IP address all at once by specifying the save destination and file name.

[ Batch write of settings ]

The contents of the setup record file including the IP address can be written to the target model. It is used when you want to copy the same settings to multiple machines or when you want to return the unit to the initial state using the factory setup record included in the attached CD.

[ Example of batch writing by LANIOset ]

■2-way for power supply

8 to 30 VDC can be supplied from either the pin header type connector or the AC adapter jack, depending on the power supply situation at the site.
In addition, by connecting two adjacent units with a power branch cable (sold separately: LAH-2XH), one AC adapter can be used to power two units, reducing installation space and cost for AC adapters.

■Robust design for FA

The noise-resistant, robust metal housing and wide operating temperature range of -20 to 55°C make it safe to use even in harsh FA environments.

    Please select the power supply (AC adapter, switching power supply, etc.) used together according to the operating temperature.

It can also be installed on a 35mm DIN rail using the separately sold DIN mounting plate (SI-DIN70/SI-DIN30).

■Compatible with 10Base-T/100Base-TX LAN networks

Built-in Lantronics device for its LAN interface. 10Base-T/100Base-TX can be automatically detected and it can be connected to the LAN. Digital signals can be monitored and controlled via TCP/IP and UDP/IP.

■Easy control from PC

Input/output can be controlled by sending a simple control command described in the instruction manual to the payload part of TCP/IP.
Units on the LAN can be identified not only by the IP address, but also by the model number and the ID number set by the rotary switch, so even if multiple units of the same model are connected to the LAN, the target unit can be identified.

LA-5R control command example (Turning DO1 and DO3 ON):

PC (etc.) -----> [TCP/IP header] + (F0h 0b00000101) -----> LA-5R
step2--LA-5R turns DO1 and DO3 ON and the other terminals OFF. Then send back the same command.
PC <----- [TCP/IP header] + (F0h 0b00000101) <----- LA-5R
Finish controlling

   If you send 2 consecutive bytes of F0h and 000xxxxxb to the local port number (factory default: 10003), DO1 to DO5 corresponding to the xxxxx bits of the 2nd byte will be set and the same 2 bytes will be returned immediately.
When the output setting bit is 0, the output is OFF, and when it is 1, the output is ON.

■Control software is attached

By using the control software (LA-PC10), you can easily perform basic operations such as checking the input status and turning ON/OFF the output signal from your PC.
From Version 1.20, you can give a name to each input/output contact.

Operating environment of control software LA-PC10
OS Windows® 10/11
   Messages are automatically switched between Japanese and English depending on the OS environment.
  • Search and display units on the LAN
  • Controls ON/OFF of output signals manually or at specified intervals
  • Displays ON/OFF of input signals manually or at specified intervals
  • Save input/output history to CSV format file at specified intervals

■Operation can be checked from a smartphone or tablet

Applications (LAAD10 and LAPulseModeAD) with which you can check the operation of LANIO from an Android smartphone or tablet via Wi-Fi are available from Google Play.

  1. You can enter an IP address.
  2. You can enter the port number. (Port number is 10003 when shipped)
  3. Tap after entering the IP address and port number to connect.
  4. Search LANIO's Mac address via wireless AP and display it in 5. (The Mac address is displayed on the label at the bottom of the LAN connector.)

[ LAAD10 device selection screen ]

  1. Tap to enter and set the name of the device to DO1.
  2. Toggle ON/OFF of the output with each tap.
  3. If checked, the output will be switched ON/OFF at the specified time cycle. The cycle can be specified in the range of 1 to 9999 in units of 100ms.
  4. You can set the specified time period.
  5. Captures and displays the input state when tapped.
  6. Tap to end the connection. Or tap the home button.

LAAD10 iOS version released

Search for “LAAD10” in the AppStore from your iPhone, etc., and download and try it.

The iOS version has a demo mode. You can check the operation image without the LANIO product itself.

[ How to use demo mode ]

  1. Open the app and tap the LINEEYE icon in the upper left three times.
  2. Press the "Search" button. If the header turns red, it means that it is in demo mode.
  3. Choose the LANIO product that was found (not actually connected) and try it out.
※To switch from demo mode to normal mode, tap the icon three times again and press the search button.

■ You can develop your own control system

I/O function library for Visual Basic, C++, and C#, and sample programs with source code (VisualC++6.0 environment for LA-5R and LA-5P-P) are available. You can quickly develop your own control system linked with other software that runs on your PC.

    You can freely use the input/output function library and sample programs, but please note that we do not provide free support regarding how to use them.
[ Examples of input/output functions ]
LE Lanio Search(int msec) Find units on LAN
LE LanioGetId(int lanio, int *id) Get ID number
LE LanioConnectByIdModel(int id, int model) Connect to specified model and specified ID
LE LanioConnectByIpAddress(char *ipaddr) Connect to specified IP address
LELANioOutPio(hLANIO handle, int pio, BOOL active) On/off control of specified "do" signal
LELANioInPio(hLANIO handle, int pio, BOOL *active) Confirm on/off of specified "di" signal

[ Program example using the library ]

■PC-less input signal extension function via LAN cable

Some models (Including LA-5P-P(G) and LA-3R3P-P(G)) can extend the signal state of the input unit side to the opposite output unit connected via a network without using a PC. LA-5P-P is capable of one-to-one-facing connection, and LA-5P-P(G) is capable of up to one-to-four-facing connection.

[ How they operates ]

The input unit (LA-5P-P, LA-3R3P-P) sends an output control LAN packet corresponding to the input state to the output unit (LA-5R, LA-3R3P-P) at power-on and when there is a change in the input signal*. Then the output unit receives the packet and controls the output signal.

Input changes -> [Input unit] -> Output control LAN packet -> [Output unit] -> Contact changes

* When the periodical notification function is enabled, control packets are periodically sent to notify the input status even when there is no input change.
LA-5P-P(G) and LA-5R(G) support 1:N and N:1 input extension

LA-5P-P(G) and LA-5R(G) can be used to transmit input from one point to multiple points, and to transmit input from multiple points to one point. Please refer to the manual for more detail.
