Wireless ON OFF Control Module 915MHz Lora Wireless I O Module 4DI
4DO Wireless PLC
1. LS-RDIO series module general introduction
LS-RDIO Modbus RTU is an industrial controller designed by Lensen
Technology. It supports point to point, point to multi-points
wireless DI, DO, AI, AO collection and control. This transceiver
has the advantage of easy installation, no program required, no
communication fee. It is reliable and cost-effective substitution
for rail signal cable, slip ring signal wire.
LS-RDIO0404 has 4 inputs 4 relay outputs and 1 RS485(wireless RS485
customized). Power output we have 2 versions, one is 100mW for 1km
LOS control distance, and another one is 1W for 3km LOS control
distance.
2. Application Field
LS-RDIO series I/O module is widely used in industry automation
like factory central data process, pump control, tank level
monitoring, Conveyor Control,oil monitoring, mining machinery,
environment monitoring equipment, lifting devices, robots control,
filling machine, mixing equipment, logistic line, AGV etc.

4. Modbus RTU communication and value calculation
A. Register types:
| Register types | Read command | Write command (Control command) | Power off | Function |
| coil register | 0x01 | Input --not support Output-support | Not keep | Can read input value |
| Hold register | 0x03 |
1) Coil register:
Input: it is not convenient to read 8 I/O at one time. In order to
control each I/O correspondingly, we defined coil register. The
register address is 0x0000-0x0007.
Output: it is not convenient to control 8 I/O at one time. In order to
control each I/O correspondingly, we defined coil register whose
address is 0x0020-0x0028.
Note: The coil is not extra resource, just a method for register
addressing---addressing by bit.
2) Holding register:
a. value of input channels: 0x0000
Note: addressing by bit means we only use the first 8 bits; bit0 to bit7 corresponds with I / O1 to I / O8;
b: feedback and value of output channels: 0x0040
Note: addressing by bit means bit 0 corresponds with 1/O1, bit 7
corresponds with 1/O8, bit 8-bit 15 corresponding value we write 0.
3) Reading method:
Coil register: Directly read the responding register. 1 means OFF,
0 means ON.
Holding register: Can read all 8 inputs state one time. We only use
bit0-bit7 of this 16-bit register; each bit represents the state of
an input.
4) Control methods:
a. Use the coil--- directly writes the corresponding coil register
you can control corresponding output.
b. Use the holding register--- eight outputs share 1 holding
register, so you can manage each bit separately to control the
responding output.
