
Critical states actions
–
it is enabled to assign actions similar to alarms to some error states,
evaluated by data logger (error of measurement on some of input channels, error in configuration of
data logger, reaching of specified occupation of data memory and self test error). Do not use zero
duration time of critical state for evaluation of the action. Use at least 10s delay. If this state lasts
this time without interruption, selected actions will be performed.

This and the following bookmark refer to data logger input channels to be switched over in left lower
window corner.
Set your own identification of measured points and optional conversion of measured values at this
bookmark:

Type of input channel
–
here select type and range of input channel. Setting must correspond with
the way of its connection to input terminals. It is possible to change if needed. If binary input or
input RS485 (if installed) is selected, several following selections can differ. Interchannel
recalculation is specific type of input channel. By means of it is possible to acquire values as sum,
difference or other combination of measured values from two another input channels:
C MV B MV A MV
k j
  
* *
C MV MV A MV
k j
 
* *
C MV MV A MV
k j
 
*
where MV are measured values, j,k are source channels

in upper part of bookmark name and range of installed input module is specified for information.

Channel name: - enter name of measured points in length of maximum 16 characters.

Physical unit (except binary inputs)
–
you can select from the list or write your own in length of
maximum 6 characters

Description of state open/closed (in binary inputs)
–
user selectable strings in length 16 of
cha
racters to describe state „closed“/ „open“ resp. „without voltage“/ „with voltage“

Number of decimal places (except binary inputs)
–
you can set maximum 5 digits behind decimal
point.

Recalculation (except binary inputs)- measured value from input can be recomputed by means of
two-point linear transformation to other value. Default state is set to conversion 1:1 and full scale
points of module input range module or value 0-0, 1-1 are used. Value can be arbitrary with the
exception of state, both input values are the same.
Example: data logger with current input 4 - 20 mA is connected to temperature transducer with
current output, which generates at temperature -
30°C output current 4 mA and at
temperature 80°C current 20 mA. Enter following values to th
e table:
Measured value 4.000 [ mA] will be shown as -
30.0 [°C].
Measured value 20.000 [ mA] will be shown as 80.0 [°C].

Processes (except binary inputs)
–
allow which processes are enabled to use. See Application notes .

Address of connected device, Maximum waiting etc.
–
setting of RS485 input, for more
information see Appendix No.2.
