Communication Manual – V1.1x

1. SERIAL COMMUNICATION

1.1 COMMUNICATION INTERFACE

The optional serial interface RS485 allows to address up to 247 controllers in a network
communicating remotely with a host computer or master controller.

RS485 Interface

 Compatible line signals with RS485 standard
 3 wire connection from master to up to 31 slaves indicators in a multidrop bus. It is

possible address 247 nodes with multiple outputs converters.

 Maximum communication distance: 1000 meters
 The RS485 signals are:

D1 = D: Bidirectional data line.
D0 =
C = GND: Optional connection which left communication better.

General Characteristics

 Optically isolated serial interface
 Programmable baud rate: 1200, 2400, 4800, 9600, 19200, 38400, 57600 or

115200 bps.

 Data Bits: 8
 Parity: None, Even or Odd.
 Stop Bits: 1

Communication Protocol

The MOSBUS RTU slave is implemented, available in most SCADA softwares in the
market.

All configurable parameters can be accessed (for reading or writing) through the
Registers Table. Broadcast commands are supported as well (address 0).

The available Modbus commands are:

03 - Read Holding Register

05 - Force Single Coil (Force Digital Output state)

06 - Preset Single Register

16 - Preset Multiple Registers (Block write to multiple holding registers)

The registers are arranged in a table in such a way that several registers can be read in
the same request.

Bidirectional inverted data line.

D:

1.2 CONFIGURATION OF SERIAL COMMUNICATION PARAMETERS

Two parameters must be configured in the device for serial communication:

bavd: Baud rate. All devices with same baud rate.
addr: Device communication address. Each device must have an exclusive address.

prty: Paraty.

1.3 REGISTERS TABLE

Equivalent to the registers referenced as 4XXXX.

The holding registers are basically a list of the internal indicator parameters. All registers
above address 12 can be read or written. The registers up to this address in more are
read only. Please verify each case. Each table parameter is a 16 bits two complement
signed word.
