Changing the recording period parameter causes losing of the relevant channel's archived data recorded in
that day at which the modifition takes place. Daily memory usage for each recording channel can be
calculated using below equation in bytes.
Memory Usage (Bytes) = (86400/Recording Period (sec))*4
As an example, when all slots are plugged with Analog Input Cards and the recording of all analog channels are
activated with a 1 sec recording period, 350 Kbytes of memory is used for each channel in a day and that
corresponds to 4.2 MByte memory usage for all channel. With 8000 MByte Micro SD Flash, recording belonging
to the last 5 years can be hold internally without any corruption. When the internal memory is full, old
records are either deleted or backup depending on Backup Type. Please see
Archive Page
for backup
configuration (
see Section 6.10
).
6.6.8. Digital Input Card adjustments
Name:
The name of the related digital input can be written by this parameter (maximum length
of 12 characters).
Description:
Maximum 50 characters long description.
Off Message:
Maximum 100 characters long alarm off message.
On Message:
Maximum 100 characters long alarm on message.
State changes in all digital input channels are recorded to
DIGITAL LOG
. In addition, the channels can also be
recorded periodically. Please check section
6.6.7 Record Adjustments
for digital input card for periodic
recording.

6.6.9. Modbus Channels Page
Up to 16 MODBUS RTU channels can be configured by this page. Firstly, channel number is clicked from the
left of the screen before starting the configuration. MODBUS channel process values are transferred from
slave MODBUS RTU devices over the RS-485 port or TCP. RS- 485 serial communication settings can be done
from Serial Port Tab in the
HARDWARE
menu. Slot Analog Channel and MODBUS channel have almost same
features except the way channel rocess values are assigned. While the former extracts the channel values
from certain sensors, the latter uses RS-485 bus or TCP by querying the slave device with
Device Address
and
Reg. Address
parameters to get the channel process values. If an error occurs while querying the slave
device, the process value of the relevant channel is set to the configured
Fault Value.
Name:
Determines the name of the selected channel with using maximum 12 characters.
Description:
Maximum 50 characters long description.
Connection:
This parameter determines connection type. When selected as OFF, the channel is
disabled and is closed for message transaction. Available connections are RS-485 and TCP.
Time Out:
Only functional for RS-485 connections and determines time out value in miliseconds. This
parameter can be adjusted between 100 and 500 miliseconds.
Address:
This parameter defines modbus slave address of RS-485 modbus connection and can be set
between 1 and 127.
IP Address:
This parameter determines IP address of TCP/IP connection and is only required for TCP
type connections.
Function:
Determines the function code which will be used when querying. 03 or 04 can be selected.
Reg. Start Adr.:
Starting adress of modbus reading query.
