ES58 • EM58 MODBUS®
When the page of the interface opens, by means of the drop-down box in the
Select serial com
drop-down box of the
SERIAL LINE
group box you can
choose the serial port the device is connected to. The port that is currently
selected is indicated in the drop-down box. If you do not know the number of
the COM port the device is connected to, select the
All coms
check box.
In the
Address
item of the
DEVICE
group box the MODBUS address of the
connected device must be entered. By default the address of all Lika devices is
“1”. If you do not know the MODBUS address of the networked device select the
All addresses
check box.
If you select the
All coms
check box and the
All addresses
check box the tool
will scan all the available serial ports (COM1 first, then COM2, COM3, etc., if
installed) and will test for each one all the baud rate and parity bit options
(9600 No parity, 9600 Even, 9600 Odd, etc.) and all the possible addresses (from
1 to 247, according to the MODBUS protocol).
It is clear that this searching operation may take a while.
To start searching and connect to the device press the
CONNECT
button in the
DEVICE
group box. While the program is attempting to connect to the device, a
green progress bar and the
Busy
label over the
Select serial com
drop-down
box indicate that the port is currently open and being checked. As long as the
communication is active the bar indicates that the port is open. When there is
no communication the port becomes available for other applications after a
timeout of about 1 second.
If problems occur while trying to establish the connection (you have selected a
wrong or not available serial port, or the port is currently busy; or you have set a
wrong node address, etc.), the interface will go on trying to establish the
connection uninterruptedly, until the
CONNECT
button is pressed once again.
The message
No com
and the name of the last address and serial port that have
been checked will appear next to the button.
