RS-485 Basics

• “Recommended Standard” jointly published by Telecommunications

Industry Association (TIA) and Electronic Industries Alliance (EIA).

• Defines the electrical characteristics of interface circuits (line

drivers/transmitters and receivers) used for serial communications

over a multipoint network. Examples include:

– Signal amplitude

– Input sensitivity

– Input impedance

• Does not define:

– Cabling

– Connectors

– Data protocol

What is RS-485?

• Balanced interface (two signal lines whose voltages are the inverse of

one another)

– Increases noise immunity and decreases emissions

• Multipoint, bi-directional communication on a single pair of wires

– Lower cabling costs

• Large differential signal (>1.5V), large common-mode range (-7 to 12V)

– Allows for communication over long distances and with large

ground potential differences

• Can achieve signaling rates up to 50 Mbps

– Suitable for a wide array of applications

Why is it used?

The resistor divider network comprised of R2 and R3:

1. Biases the receiver input relative to the local VCC and ground, allowing

the receiver to operate without a ground wire.

2. Attenuates the voltages appearing at the A and B terminals (which may

range from -7V to +12V) to operable levels between VCC and ground.

RS-422

• Like RS-485, RS-422 is a differential signaling standard which defines the electrical

characteristics of drivers and receivers used to implement a balanced transmission line.

• Unlike RS-485, RS-422 is a multi-drop standard, rather than multi-point, allowing only one

driver and up to ten receivers to be connected to the bus.

• Any RS-485 compliant transceiver is compatible with an RS-422 application, though it may

not be strictly compliant with the RS-422 standard.

RS-485 Applications Tips

11

1) Use twisted pair cable.

• Z0 = 120Ω or 100Ω

2) Connect nodes via daisy-

chain.

3) Terminate unused conductors.

• RT = Z0/2

4) Terminate one end.

• RT1 = Z0

5) Apply failsafe biasing to the

other end.

6) Terminate this end.

• RT2 = [2RFS • Z0] / [2RFS – Z0]

7) Determine maximum

distance/data rate.

8) Minimize stub lengths.

• Lstub ≤ 3 •10-4 •tr •v

9) 3V and 5V XCVRs are

interoperable.

10) Use SM712 for ESD, EFT,

and surge protection.

11) Limit currents with 10Ω

pulse-proof resistors.

12) Filter signal between XCVR

and UART.

13) Isolate when GPD ≥ 7V.

serial port of a computer to a modem or

other peripheral devices.

• The current version of the standard is TIA-

232-F issued in 1997

The image at left shows the

transmission of a data word using the

common “9600 – 8 – none – 1” UART

format. This means that the baud rate

is 9600 bps, the word length is 8 bits,

no parity bit is used, and one start/stop

bit is used:

• The start bit is indicated by a “0” bit

(i.e., a positive voltage)

• Next, the data is transmitted LSB

first. (This example shows

transmission of 0100001, or the

letter “A.”)

• The stop bit is indicated by a “1” bit

(i.e., a negative voltage)

Controller Area Network (CAN)

CAN (Controller Area Network)

• The CAN standard defines both a protocol and a physical layer for asynchronous, serial

communication in multi-point bus applications.

• Each node consists of a CAN transceiver and CAN controller (MCU).

• A unique driver structure results in differential signaling levels different from RS-485,

which accommodate additional features in protocol. 30

CAN Physical Layer

31

VD = CANH – CANL

Recessive when VD ≤ 0.5V Dominant when VD ≥ 0.9V

A CAN compliant driver must produce at least 1.5V across a 50Ω load.

CAN Data Frame

32

• Start of Frame – A dominant bit begins the frame and initiates arbitration

• Message Identifier – 11 or 29 bit identifier used for arbitration priority

• Control Field – Specifies the length of the data to be transmitted

• Data Field - Data

• CRC Sequence – Cyclical recovery checking

• ACK – Acknowledges the CRC status of receiving nodes

• End of Frame – Marks the end of data and remote frames

33

CAN Data Arbitration • The CAN physical layer allows for priority based arbitration based on the 11-bit identifier of each module.

– 000 0000 0000 is the highest priority identifier.

– 111 1111 1111 is the lowest priority identifier.

• During each bit of the identifier frame, each node will monitor the bus and compare the bus state with the state it is

driving.

– If the XCVR transmits a logic “1” and receives a “0”, it will stop transmitting.

– The node will attempt to access the bus again after the next inter-frame spacing occurrence.

IO-Link

IO-Link

40

• IO-Link is a serial, bi-directional, point-to-point

protocol and interface standard for sensors

and actuators in factory automation

applications.

• Standardized in IEC 61131-9, and is the first

worldwide standard for communication with

sensors and actuators.

• Standardized cabling and connectors provide

power (2 wires) and data (1 wire).

• Extends existing implementations by

providing process data, as well as

parameterization, diagnostic information, and

configuration programming.

device node may support only one. Communication is initiated by the master

node transmitting test sequences to adapt to the data rate of the device node.

failure, the master signals a failure to the higher-level controller.

• 7V to 36V supply voltage

• IO-Link, PNP or NPN or configurable output

• Low residual voltage of 1.75V at 250mA

• Tolerant to ±65V transients < 100µs

• Reverse polarity protection of up to +55V

• Integrated protection on L+ and CQ

• +4kV IEC 61000-4-4 (EFT) Criterion A (5/50ns)

• +1.2kV/500Ω IEC 61000-4-5 (Surge) (1.2/50μs)

• Configurable current limit up to 350mA

• <2uA CQ leakage current

Development Tools Design Resources

The TIOS101-5 EVM provides users with the ability to

evaluate TI's TIOS101x family of Digital Output (SIO)

drivers. The EVM includes the TIOS101-5 which includes an

on-chip 5-V LDO. With pin to pin compatibility throughout the

TIOS101 family, the EVM can also support the TIOS101 (no

LDO) or the TIOS101-3 (3.3-V LDO).

This design features the TIOS101 digital output driver and detect

magnetic fields and toggles its output when the magnetic field

strength exceeds a specific threshold. The design size is

optimized to fit into small cylindrical sensors and measures only

3mm x 15mm.

The TIDA-01335 builds upon the TIDA-00188 design by utilizing

the TIOL111’s small 2.5 x 3mm package and integrated EMC

protection to reduce the PCB by ~20%. This design allows

designers to easily see how TIOL111 can fit into cylindrical

sensors.

TIDA-00731: IEC ESD, EFT, and Surge RS-485 Bus Protection

EFT setup

Transient energy:

Surge >> EFT >> ESD

Transient Protection Example

TIDA-00731: IEC ESD, EFT, and Surge RS-485 Bus Protection

• TVS (Transient Voltage Suppressor): provide protection against ESD, EFT, Surge

transients. It acts as a clamping circuit to redirect any high energy pulses to ground and

away from the transceiver.

• Pulse-proof resistors: limit the residual clamping current the transceiver sees if the TVS

clamping voltage is higher than the specified maximum voltage of the transceiver bus pins.

• TBU (Transient Blocking Unit): shield the TVS diode and the RS-485 driver from AC

power cross events or large transients as well as overcurrent conditions. When the

transient current exceeds the trigger current level on the TBU device, the TBU clamps or

crowbars the current to a safe level by transitioning to a high impedance state.

• MOV (Metal Oxide Varistor): protects the TBU device from high voltage surges caused by

lightning strikes, power contact, and power induction. The MOV device has a fast turn on

time and a high current handling capability to protect the TBU, TVS and RS-485

transceiver.

• THVD1419 and THVD1429 integrate TVS diodes in SOIC-8 for IEC Surge + ESD +

EFT protections.

• Surge protected RS485 for outdoor communication blog

• Surge protected RS485 communications video

High-Voltage Stress to Bus Line Bus-Fault Protection Bus-line overvoltage faults can happen:

• Short to power supplies, Mis-wiring, Connector failure, Cable crushes, Tool mis-application

• High clamp voltage from TVS during high transient voltage

• PTC fuse (Positive Temperature Coefficient): temperature ↑ Resistance ↑ limit current flow

• SIDAC (Silicon Diode Alternating Current): after break-over, voltage is related to the current a low voltage with high

current. After high voltage is removed, SIDAC returns to non-broken over status.

Transient Protection Example: TIDA-060027: Protecting RS-485 transceivers from sustained high

voltage/electrical over-stress reference design

THVD2410 and THVD2450 support up to +/-70V bus fault & IEC ESD/EFT protections
