Frequently
Asked Questions Here below are the most frequently asked questions and their answers:
Question Answer
I cannot access some parameters.
Some parameters are not accessible. See the documentation to find
out whether these elements can be changed. Example of an element
that cannot be changed: Counter function block counting direction.
This element is only accessible by wiring in a ladder diagram line.
I still cannot access some parameters.
To access the parameters, you must use the navigation keys and
to position the cursor above them. The and are used to
change these values. Then press Menu/OK to confirm the changes.
I cannot RUN my smart relay even though I
enable the RUN/STOP option in the main menu
using the
Menu/OK key.
CAUTION, make sure that the error symbol (!) is not displayed in
the contextual menu line. Correct the error in order to RUN the
smart module.
I would like to change my diagram lines but the
Menu/OK key no longer works.
Ensure that the smart relay is indeed stopped. Changes in RUN
mode are not allowed.
When I try to change my diagram lines, the smart
relay shows me a screen with only line numbers
(LINE No.). Have I lost all my work? Not necessarily, this situation may occur when 4 consecutive
blank lines have been inserted at the start of the ladder diagram or
between the command lines.
I have a ladder diagram that uses the Z key ( ,
, , ) for a pushbutton. I would like to test it
but when I display the diagram dynamically, my Z
key is no longer operational. Can I make it work?
No this is impossible.
I generated a ladder diagram on a smart relay
with a clock. Can I use a backup memory to
transfer it to a smart relay without clock?
No this is impossible.
When entering a ladder diagram, the clock
function blocks do not appear when choosing the
contacts. Is this normal? It is quite possible that the smart relay is one without a clock.
Consequently, the clock function blocks are not accessible. Check
the product reference numbers.
When entering a ladder diagram, the analog
function blocks do not appear when choosing the
contacts. Is this normal? It is quite probable that the smart relay does not have analog
inputs. Consequently, the analog function blocks are not
accessible. Check the product reference numbers.
Compatibility between the version of the programming software and the version
of the firmware on the smart relay
Introduction The section below describes the compatibility between the versions of the
programming software and the versions of the firmware on the smart relay.
In the Case of a
Transfer of the
Program from
the PC to the
Smart Relay In the case of a transfer of the PC program to the smart relay, all the versions of the
programming software are compatible with all the versions of the firmware on the
smart relay.
During transfer of the PC program to the smart relay, the firmware associated with
the version of the programming software is transferred to the smart relay.
In the Case of a
Transfer of the
Program from
the Smart Relay
to the PC In the case of a transfer of the program from the smart relay to the PC, compatibility
between the version of the programming software and the version of the firmware
on the smart relay is as follows:
Smart relay firmware version
V2.xx V3.xx V4.xx
Version of the
programming software V2.4 Compatible Incompatible Incompatible
V3.1 Incompatible Compatible Incompatible
V4.1 Incompatible Incompatible Compatible
