from AC lines can lead to dangerous voltage in the circuits.
4.5 Connection to the outputs
Figure 4.4 shows the connection of the load to the outputs of the transistor switch type.
Fig. 4.4 External connections to digital outputs of the transistor switch type
The positive pole of the supply voltage of the outputs is fed to the + U1, + U2 terminal to power the
outputs DO1–DO8, DO9–DO16 respectively.
It is allowed to use one or two different power sources for connection to the terminals + U1 and + U2.
It is allowed to use power supplies with different rated output voltage in the range of 10 … 36 V.
The common power supply terminals of the outputs (COM) are integrated inside the module.
The maximum length of the power supply line of the outputs from the power supply to the + U1, + U2
terminals is 30 meters.

Under the module faceplate there are terminal blocks and a service button (Figure 4.1).
The service button performs the following functions:
– Factory settings restore (Section 6.6);
– IP-address assignment (Section 6.2);
– Firmware update (Section 6.4).
5.3 Real time clock
The Module has a built-in real time clock (RTC). Its source of power is a battery.
The timing is in seconds, starting with January 1, 2000 at midnight UTC. RTC indication is used for
writing entries into the log file.
5.4 Log file
The module has built-in encrypted flash memory. The encryption algorithm is Data Encryption
Standard (DES) in cipher block chaining (CBC) mode. The key is the string superkey. An
initialization vector is generated using a hash function. The function argument is the password
specified in akYtecToolPro. A checksum is calculated by the CRC32 algorithm and saved in the file
end. The checksum is also encrypted.
Log file of Module will be saved as a few files. The log interval, the restriction on the size of one file
and their number is set by the user in akYtecToolPro. If the log file is full, then the data is overwritten,
starting with the oldest data in the oldest file.
A log file is a collection of records. Entries are separated by line break characters (0x0A0D). Each
entry corresponds to one parameter and consists of fields separated by the “;” character (without
quotes). Entry format is shown in table.

to reverse the byte order and add the offset constant (number of seconds between 00:00:00 01/

–0x3B – separator;
– 0x31 – parameter status (1 – parameter value is correct);
–0x0A 0x0D – line break characters.
The time is written to the file from the built-in real time clock. You can also set the time zone, which
will be read by external software.
The log file in the Device is written with a interval specified by user. Writing occurs with a certain
frequency, calculated in such a way that the resource of Device flash memory is sufficient for a
period of at least 10 years of operation.
Log file can be read:
– by akYtecToolPro;
– by user software (using Modbus function 20).
The list of logged parameters is available in the akYtecToolPro software on the Device Information
tab. The order of writing parameters to the log file corresponds to the order of parameters on the tab.
NOTE
After updating the firmware, all device settings except the network settings will be reset to the
factory settings.
The log file is read using the Modbus function 20 (0x14). This function returns the contents of the
registers of the memory file. The function allows using one request to read one or several records
from one or several files.
The file read request for each entry indicates:
– link type, 1 byte (should be equal to 6);
– file number, 2 bytes;
– starting address of the register inside the file, 2 bytes;
– number of registers to read, 2 bytes.
NOTE
The file number in the Mobus request is calculated as 4096 + the file sequence number.
Sequential file numbering is from scratch. The Last log file index contains the sequential
number of the log file for the last time data were written.
The number of readable registers in the request should be selected so that the length of the
response does not exceed the allowable length of the Modbus packet (256 bytes).
The size of the log file is not known in advance, so you should read portions of the data using
separate queries. If in response to the request a message is received with error code 0x04
(MODBUS_SLAVE_DEVICE_FAILURE), then you can conclude that the addresses of the registers
in the request are outside the file. To read the latest file data, you need to reduce the number of
registers in the request.
CAUTION
When the Module power is turned off, the last entry made at the time of power off may not be
saved.
5.5 Data exchange modes
The Module has the following data exchange modes:
