"Modbus device address (slave address)".
Further details on using the Modbus protocol are provided in document  [4] (page 1).
d) Setting time windows for future data retrievals
In the basic configuration now set up, you can define time windows during which data can be
retrieved cyclically from the EK205-M via the RS485 bus. Time windows 3 and 4 are provided
for operating the EK205-M with a directly connected terminal interface, with time window 3
being the one which is normally used. You can deactivate time windows which are not needed
by setting the start and end of the time window to the same value.
At the top of the device window, open the path "Parameters" > "Interfaces" by clicking on

e) Data retrieval using the RS485 interface
Check the following points if data retrieval via the device connected to the RS485 interface does not now
work:
•
Are the wire straps between signals T+ and T- and between R+ and R- connected with
the correct polarity as described in section
(Attention: the sequence of "+" and "-" is different for T+ and T- than for R+ and R-!)
Is the power supply to the "Uext" terminals on the EK205-M switched on?
•
•
Does the connected device send the device address set as described in
the connection is established?
•
Is the time window set as described in
8.2.2.2 d) active? You can check this
as follows:
- Start enSuite and establish the communication link to the EK205-M via the
optical interface ( section
EK205-M via optical
- Select "Navigation" on the left-hand side and then
of the navigation window.
- In the top part of the device window, open the path "Parameters" by clicking on the
relevant plus sign and then select "Status" and the
right-hand window.
- Check whether there is a line there with the entries "St.3", "16" and
- If this is not the case, set the time window as described in section
•
Complete a reset on the terminal interface of the EK205-M:
- Start enSuite and establish the communication link to the EK205-M via the
optical interface ( section
EK205-M via optical
- Select "Navigation" on the left-hand side and then
of the navigation window.
- In the top part of the device window, open the path "Parameters" > "Interfaces" >
"Terminal interface" by clicking on the relevant plus signs.
