1. Description
1.1 Function
Digital input module MV110-16DN is an expansion module with 16 digital inputs.
The module has the following functions:
–Connecting peripheral devices with digital outputs
–Interpretation of digital signals
–Pulse counter (see 1.2)
–RS485 network state diagnostics
–Generating corresponding fault and alarm signals
–Slave in Modbus network
The module supports Modbus RTU, Modbus ASCII protocols with automatic protocol
identification.
The module is to be configured using ‘M110 Configurator’ software via RS485-USB inter-
face adapter IC4 (not included). The latest version of the configuration software is availa-
ble for download on www.akytec.de.
1.2 Counter function
The module also has the ability to use all of its inputs as fast 16 bit counters with a count-
ing frequency of up to 1 kHz. The minimum pulse width is limited to 0.5 ms. Pulses of
higher frequency or of shorter duration are ignored. The counter is responsive to any
rising edges.
When switching off power, the actual count state remains retained in permanent memory.
The counter is set to 0, if it has been reached an overflow, and counting continues.
The module has a debouncing function. This function can be activated for each input by
setting tin.c (debouncing filter) to "On" when making configuration of device parameters
(see Table 5.1). The function is recommended at signal frequencies up to 90 Hz and if
the duty cycle is 50% and more.
1.3 RS485 network
I/O modules of Mx110 series use common standard RS485 for data exchange. RS485
serial interface is based on two-wire technology and half-duplex mode. Protocols Modbus
RTU, Modbus ASCII and akYtec are supported. 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 the network length can be increased using a RS485 interface repeater.
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 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 terminat-
ing resistors of 150 ohm.
The module can be used as slave devices only. Master device can be PLC, PC with
SCADA software or control panel.
1.4 Construction
─Enclosure: Plastic, grey, for wall and DIN rail mounting
─Terminal strips: 2 extractable terminal strips with 20 screw terminals each
─LED „POWER“: power supply
─LED „RS-485“: blinks when exchanging data at serial port
─LED „FAULT“: lights up when the data exchange process on serial port is bro-
ken
─16 LEDs „INPUTS“: light up, when at relative input is 1

–The maximum conductor cross-section for power supply is 1.5 mm2
►
NOTICE
EMC-safety
Signal cables should be routed separately or screened from the supply cables.
Only shielded cable may be used for data transmission and signal lines.
Shield in the control cabinet for best electromagnetic immunity recommended.
–Connect the RS485 line to the terminals D+ and D-.
–Use twisted pair cable for RS485 connection. The length of the line should not ex-
ceed 1200 m.
4.1.1 Hardware write protection of permanent memory

The following steps are required:
–Switch off the power supply
–Open the cover on the front panel of the module (see Fig. 4.1)
–Put the jumper X1 in the position “closed”
Thereby the following is to observe:
–To change the configuration parameters, the jumper X1 must be removed again.
–As long as jumper X1 is put, the input counter will be reset after any power loss.

NOTICE
Before starting
Before switching on, make sure that the device has been kept at the specified
ambient temperature (-20... +55 ° C) for at least 30 minutes.
Parameters of the module can be read, edited and saved with ‘M110 Configurator’ soft-
ware. The full list of parameters is shown in the Table 5.1.
Module has to be configured first before operating in RS485 network.
The following steps are required:
–Install M110 Configurator on the PC.
–The module should be connected to USB port of the PC over a USB/RS485 adapter
(not included). Connect the D+/D- terminals of the module with the D+/D- contacts of
the adapter.
–Connect the power supply to 24V/0V terminals of the module.
–Turn on the power supply.
–Run the Mх110 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 have to be changed.

11
6. Operation
In the operation mode the module is controlled by a network Master in Modbus network.
In addition, the input states and counter states can be read out and the counter states
can be set to 0 (see 6.1).
Modbus functions 03, 04 for reading and 16 for writing can be used.
6.1 Input and counter status
The input status can be read out as a bitmask. The corresponding Modbus registers can
be taken from the table 6.1. The least significant bit of the mask corresponds to the
input 1.
To reset the counter, write 0 to the corresponding register.
6.2 Fault condition
If the data exchange on the serial port is interrupted (i. e. there is no command from the
master within the time specified by the parameter t.out), the following applies:
–LED FAULT flashes.
–Once a request from the master device comes, the display ‘refreshes’.
–If t.out parameter is set to 0, ‘Fault Condition’ is not defined.
