1 Description
1.1 Functions
MU110-6U is an extension module with 6 analog outputs.
The module provides following functions:
─module control and parametrization via RS485 network
─RS485 Network diagnostics
─error and alarm signal generation
─Slave in the RS485 network.
The module is to be configured using ‘M110 Configurator’ software via RS485-USB
interface adapter IC4 (not included). The latest version of the configuration software is
available for download on www.akytec.de.
1.2 RS485 network
The I/O modules of Mx110 series use the common standard RS485 for data exchange.
The serial interface RS485 enables communication via two-wired line in half-duplex
mode. The module supports the Modbus RTU and Modbus ASCII protocols with automat-
ic protocol detection The network consists of a Master device and can contain up to 32
Slave devices. The maximum length is 1200 m. The number of slave devices and net-
work length can be increased using RS485 interface repeater.
Separate devices are connected to a network according to linear (bus) topology. It means
that the line goes from the first device to the second one, from the second one to the third
one, etc. Star connections and spur lines are not allowed.
Line reflections always occur at the open bus ends (the first and the last node). The high-
er the chosen data transmission rate, the stronger they are. A terminating resistor is
needed to minimize reflections. Experience proves that the most efficient practice is to
use terminating resistors of 150 ohm.
The modules can be used as slave devices only. Master device can be PLC, PC with
SCADA software or control panel.
1.3 Design
─Enclosure plastic, grey, for DIN-rail or wall mounting
─Terminal blocks 2 plug-in terminal blocks with 24 screw terminals
─LED “POWER“ power supply indicator
─LED “RS-485” flashes at data exchange via RS485 interface
─LED “FAULT” lit when data exchange via RS485 interfaces interrupted
Dimensional drawings are given in App. A.
There are three jumpers under the front cover (see Fig. 4.1):
─X2 −restore factory settings (see 7)
─X3 −service function
─X1 −DRAM write-protection (see 4.1.1)
All jumpers are in OFF position by default.

5 Configuration
Before starting
Before switching on, make sure that the device was stored at the specified ambi-
ent temperature (-20 ... +55 °C) for at least 30 minutes.
Parameters of the module can be read, edited and saved with “M110 Configurator”
software .The full list of parameters is shown in the Table 5.1.
To control the module via Modbus network refer section 6.3 “Modbus addressing”
The module should be configured first before operating in RS485 network.
Proceed as follows:
─install the configuration software “M110 Configurator” on the PC
─connect the module to the USB interface of the PC over RS485-USB interface
adapter IC4 (not included)
─connect the power supply to the terminals 24V / 0V
─turn on the device
─start the M110 Configurator
If the factory settings of the module have not been changed, the connection to the mod-
ule is automatically established, the module automatically recognized, its configuration
parameters read out and an appropriate configuration mask open.
If it does not happen, parameters of the configurator should be changed.

6 Operation
The module is controlled by the Master device in a RS485 network. The addresses from 1
to 247 can be used. The address 0 is reserved for broadcasting.
The following Modbus functions are supported:
─03 (0x03) Read Holding Registers
─04 (0x04) Read Input Registers
─16 (0x10) Preset Multiple Registers
The register addresses is given in Table 6.2.
The output status according to the output value is given in Table 6.1.

* Note:
The configuration program uses internal communication protocol instead of Modbus pro-
tocol. For this reason the ranges of output value during configuration and in Modbus
command can differ. For example, in order to activate output AO1 during the functional
test, the output value should be set to 1, but in Modbus command the output value 1000
should be recorded in the register 0000.
6.1 Output functional test
In order to check the functioning of the device outputs procced as follows:
─Connect the module to the computer USB-port via USB/RS485 adapter
─Connect a voltmeter and a resistor box as shown in Fig. 6.1
─Start the configuration program "M110 Configurator"
─If connection with the module has not been established automatically, network
parameters of the configuration program should be changed
─Select the menu path "Device -> I/O Status…" to open "Output status" window
─Set individual outputs to 0 or 1 to check their functionality
─The functional test is successful, if the voltage is within the range between 0±0.05
V at 0 and 10±0.05 V at 1.
─Contact the Technical Support of akYtec GmbH in case of any deviations.

6.2 Fault state
If data exchange via RS485 is interrupted, i.e. the command is not received from the net-
work Master within the time specified in t.out parameter, then all outputs with the pa-
rameter Log=0 will be set to the safe state. The safe state is the output value specified in
the parameter O.ALr(Safe output status) for each output. In this case:
─LED FAULT is on
─LED FAULT is off with a new query received from the Master
─The outputs remain in the safe state until the command from the Master about
status change is received
─If t.out parameter is set to 0, the fault state doesn’t occur.
Parameters t.out and O.ALrcan be set during configuration or operation and are saved
in the non-volatile memory.
►
NOTICE
Non-volatile memory
Since the non-volatile memory is not unlimited rewritable (~ 1 million), it is not
recommended to change the Safe output status (O.ALr) by a Modbus command so
often as the output value.
