4.2 Real time clock
The module has a real-time clock (RTC) with a back-up battery (Sect. 4.3). The RTC time is counted
as UTC in seconds, starting from 01/01/2000, 00:00.
To set the time, click the toolbar icon Real-time clock (Fig. 4.1).
Use the button Synchronize with PC to synchronize the RTC with the PC clock.
Select your time zone from the drop-down list below. You can also set the time zone in the range
-720...+840 min. with a 60 min. step in the parameter group Real-time clock.
Use the button Save to save the parameters in the device memory.
Fig. 4.1 Real-time clock parameters
The RTC is used for calculation of measuring timestamps (Sect. 4.8.5) and of Time (ms) parameter.
Time (ms) is a cyclic time in milliseconds that starts with turning on and stops with turning off of the
device. It is reset to zero at the end of cycle (4294967295 ms). The parameter is used for device
diagnostic purposes.
To set the RTC time over Modbus network, proceed as follows:
1. Write the new time in the parameter New time.
2. Set the parameter Apply new time = 1 and hold the value for at least 1 second.

4 Configuration and operation
11
akytec GmbH - Vahrenwalder Str. 269 A - 30179 Hannover - Germany Tel.: [phone] - www.akytec.de
3. Set the parameter Apply new time = 0 and hold the value for at least 1 second.
The time value cannot be changed more than once per second.
4.3 Battery
The RTC is powered by the supply voltage. When the device is powered off, RTC is powered by a
replaceable battery of type CR2032.
A fully charged battery can power the RTC for 5 years. At the temperatures near the permissible
limits (Tab. 3.2), the battery life time is reduced.
The parameter Voltage in the group Battery shows the battery voltage in mV.
The battery status is updated each time after powering on and then every 12 hours.
The battery should be replaced if at least one of the following events has occurred:
– LED indicator lights up for 0.2 s with a period of 2 s, which means that UB≤ 2 V and the battery
has to be replaced as soon as possible, but the RTC can still work for about 2 weeks without
power supply.
– The battery was last time replaced 6 years ago.
For battery replacement, see App. C.
NOTE
If the battery voltage is less than 1.6 V, the configuration parameters are written to the
battery-backed RAM and then transferred to the flash memory. The recording interval
depends on the load of the module processor (at least 2 minutes).
Since the number of erase cycles of the flash memory is limited, it is not
recommended to record the configuration parameters cyclically when the battery is
low.
4.4 Ethernet
To configure the Ethernet interface, open the node Network > Ethernet in the parameter tree.

again to the project with the new network parameters.
If a dynamic IP address is required (e.g. to use a cloud service), set DHCP to On.
4.4.1 Network parameters setting using service button
If you need to assign IP addresses for several modules, it is more comfortable to use service buttons
on devices (Fig. 2.2. Pos. 7), previously having all the modules connected to the PC over Ethernet.
To change the Ethernet parameters using service buttons:
1. Connect all modules in series to the PC over Dual Ethernet ports (Fig. 2.3. Pos. 2)
2. Power on the modules
3. Start akYtecToolPro
4. Set the parameter DHCP to Service button on all modules
5. Click the toolbar item IP addresses
6. Set the IP address for the first module from the group
7. Press the service buttons on the modules sequentially, checking the result in the dialog box,
where will be indicated on which module the button was pressed. The specified static IP address
and other network parameters, if any have been changed, are assigned to this module. The
address is automatically incremented by 1 for each subsequent device.
Only Ethernet parameters will be changed, other parameters will not be affected.
If you forgot the IP address of the device, restore the factory settings (Sect. 6).
4.5 Modbus Slave
The module can operate in Modbus TCP network as a slave, using the port 502 and the standard
address 1. The address can be changed in the group Modbus Slave (Tab. 4.2).
The device can handle maximum 4 Modbus TCP connections.

Log files are stored in a built-in flash memory, formatted as a file system with encryption. For flash
memory specifications see section “Flash memory” in Table 3.1.
If an archive overflows, the new entry will overwrite the oldest one in the archive.
The archiving parameters are described in Tab. 4.5.
To view all logged parameters, use the toolbar item Device information in akYtecToolPro.
The archive can be read with via Modbus TCP using function 20 (Tab. D.3). This function allows
reading one or several records from one or several files in one request. For details on function usage
see Modbus specifications.
The file number in the Modbus request should be calculated as file ID + 4096. File indexing starts
with zero. The parameter Last log file ID contains the ID of the archive file to which the data was
last written.
The time zone is not contained in the file but can be read from the parameter Time zone (Tab. D.1).

4.7 Analog outputs
The device has 8 analog outputs. Each output can be configured for the following operation mode:
– 0 … 20 mA;
– 4 … 20 mA;
– 0 … 1 V;
– 0 … 10 V.
Each output can be configured to any of the above modes of operation, regardless of the mode of
operation of other outputs.
The level of the analog output can be set by writing values to the corresponding registers using the
Modbus protocol. The value is set in fractions of percent from 0 to 1000 (which corresponds to a
value from 0 to 100% with an accuracy of 0.1%) or in physical quantities – microamperes (for the
modes 0 … 20 mA and 4 … 20 mA) or in millivolts (for the modes 0 … 1 V and 0 … 10 V). When
setting a value in one register, the value in the other is automatically recalculated.
4.7.1 Safe output status
For each output, it is possible to set the safe state of the output in the Safe state parameter (from 0
to 100%).
The output switches to the safe state, if at the time of turn-on or during the time-out there are no
commands from the Network Master. If the time-out value is set to 0, then the output does not go to a
safe state.
When the main power supply of the Module is disconnected and the output elements are powered,
all outputs will switch to the 0 V (for modes 0…1 V and 0…10 V), 0 mA (for mode 0…20 mA) and 4
mA (for mode 4…20 mA) state. The maximum time to go to a safe state after the main power supply
fails is 9 seconds.

4.7.2 Output diagnostics
Following output malfunctions can be detected:
– no DAC response (no output power supply)
– load short circuit (only for 0…10 V)
– no output load (only for mode 0…20 mA and 4…20 mA)
If a fault is detected, 1 is written to the corresponding bit of the output bit mask. The type of error is
written in the output state register. The failed output indicator lights red.
If the fault type is Output stage overheating or Load short circuit, the faulty output is switched off
periodically to keep it working.

4.9 MQTT protocol
4.9.1 Basics
The MQTT protocol defines two types of network entities: a message broker and a number of
clients. Broker is a server that receives all messages from the clients and then routes the messages
to the appropriate destination clients. Client can be publisher or / and subscriber.
Published messages are organized in a hierarchy of topics. When a publisher has a new data to
distribute, it sends a message with the data under the particular topic to the connected broker. The
broker distributes the message to any clients that have subscribed to that topic.
A topic is a UTF-8 encoded character string that the broker uses to filter messages for each
connected client. The topic consists of one or more topic levels. Each topic level is separated by a
forward slash (topic level separator).
When a client subscribes to a topic, it can subscribe to the exact topic of a published message or it
can use wildcards to subscribe to multiple topics simultaneously. There are two kinds of wildcard
symbols: single-level (+) and multi-level (#) (see Example).
4.9.2 Implementation
The module supports the MQTT protocol (v3.1.1) and can be used as client. It can publish
information about the status of its inputs and outputs and can be subscribed to topics which control
its outputs.
To configure the MQTT parameters, open the MQTT group in the parameter tree.

When using the MQTT protocol, it is recommended to set the parameter "Safe state
timeout" (“Modbus Slave” group) to 0, since writing is usually event-driven and not
cyclic in this case.

4.10 SNMP protocol
4.10.1 Basics
The protocol is based on the Client / Server architecture, where clients are called managers and
servers are called agents.
Managers can read (GET) and write (SET) agent parameters. Agents can send messages (traps) to
managers about changes in any parameter.
Each agent parameter has a unique identifier (OID – object identifier), which is a sequence of
numbers separated by periods.
4.10.2 Basics
The protocol is based on the Client / Server architecture, where clients are called managers and
servers are called agents.
Managers can read (GET) and write (SET) agent parameters. Agents can send messages (traps) to
managers about changes in any parameter.
Each agent parameter has a unique identifier (OID – object identifier), which is a sequence of
numbers separated by periods.
4.10.3 Password
You can use password to protect the configuration parameters of the device from an unauthorized
access. To set the password, use the toolbar item Password or the same item in the device
context menu. There is no password by default.
If you forgot the password, restore the factory settings (Sect. 6).
