R560
Universal analogue input module
Summary
The R560 is a microprocessor controlled, communicative module with 8 analogue
inputs with variable measuring range: voltage, resistance, temperature, current
loop). The module uses a RS485 bus for communication, and can be easily
integrated in a variety of supervision and control systems.
Application
•Building and industrial control systems –measuring of temperature,
pressure, and other values
Function
The module incorporates 8 analogue inputs. The input signals are processed and
multiplexed into a 16 bit A/D converter. Each input is rangeable separately (see
Technical data), and inputs can also be used as 0 to 20 mA current measurement
inputs if the corresponding DIP switch is activated.
The module communicates by means of RS485 data bus. The Modbus RTU
communication protocol ensures smooth and easy integration in a variety of control
and data acquisition systems. It connects to process stations (PLCs) directly or
through the M012 interface (RS485 to RS232 converter with galvanic isolation).
Removable connectors are used for all signals as well as for data line so that
mounting is fast and easy. The module has a DIN rail clip.
The communication circuits are protected against overvoltage and galvanically
isolated from other parts of the module. If the module is terminating the
communication bus, i.e. it is the first or last in line, a terminating 120 resistor may
be switched on by activating the BUS END switches. Two LEDs located inside of the
housing enable fast diagnostics –power and communication.

All module settings are backed up in an EEPROM chip. The module is equipped with
a watchdog circuit.
See domat - Technical application notes for connection examples. R560 is a more
universal replacement of M550 (which has 8 inputs for passive sensors) and it can be
used also as a replacement of M500 (8 voltage inputs) for most of the applications.
Please note that the R560, unlike M500, has asymmetrical inputs (0 to 10 V rather
than -10...10 V).

controllers (Domat PLC… for example) just like at e.g. MCIO2
module. In the R560 module there is recalculation to °C for
the Pt1000 sensor only.

DIP 8 = bit 0; switches increase their bit weight from
right to left, see below
BUS END
Switch for bus RS485 termination (located at the RS485
connector); ON = bus end; the first and last devices on
bus should have bus end ON

0 … 20 mA
For current measurement (0-20 mA) on individual
channels switch the particular DIP switch to ON
The 0...20 mA range must be also set over Modbus (e.g.
using Domat ModComTool)

Dimensions
Dimensions are in mm.
Installation
The R560 module is fixed on standard DIN rail (by snapping).
When removing the module from the DIN rail proceed as follows: Place a
screwdriver in the plastic slot which is in the middle of bottom part of the module
(1). Then push the screwdriver upwards (2). After that, the module can be removed
by tilting it upwards (3).
Addressing
The Modbus address can be set as follows:
-hardwarewise: using DIP switches. The switches increase their bit weight
from right to left, see image with example where address of 21 is set by
activation of switches 4, 6, and 8 with bit weight of 16, 4, and 1 respectively.
Valid settable range is 1 to 254. Address 0 (all switches OFF) means that the
address is set as entered in the Modbus table. Address 255 (all switches ON)
brings the module to INIT mode, where Modbus address is 1 and
communication parameters are set to N, 8, 1, see image below.
All changes apply after the module is switched off and on again.

-softwarewise using the ModComTool software, available for free
at www.domat.cz. The default address (factory setting) is 1, default
communication parameters are 9600, 8, N, 1. Parity and stopbits can be set
in Modbus register 1005 LSB.
The software address is only active if the hardware addressing switch is set
to 0.
All changes apply after the module is switched off and on again.
