Communication menu
Online
The
Communication-Online
menu allows to re-establish the serial link after it has been stopped by the user
with the Offline command. When clicking Online, the software executes a complete scan of all configured
DMK, to verify their status.
Offline
With communication-Offline the user has the possibility to temporarily suspend the serial communication link
between the PC and the DMK network.
This command is to be used when, for instance, it is necessary to modify the network wiring or when DMK
are to be switched off. The System Offline status is displayed on the main page Toolbar (at the bottom of the
main window).
The system passes automatically in Offline mode when the user opens the
Configuration
window.
Modem Call
To connect to one or several DMK via a couple of modems, it is necessary to select the Modem connection
checkbox in the
Configuration-Options-General
window. Selecting modem communication will automatically
change the communication protocol used by the software, from the standard Modbus RTU to Modbus ASCII,
which can be used with modems. From the user point of view, the difference between those two protocols is
only a little slower speed in case of the ASCII protocol, due to its length that is double than the RTU and the
modem modulation that requires also a certain amount of time.
When the program is configured for modem communication (see
Configuration-Options-General
window) it
automatically shows the modem call dialog after it has been started, because it is not possible to
communicate with the DMK before dialing the phone number of the remote modem. The same window can
be opened manually using
Communication-Modem call
menu or the dedicated pushbutton on the toolbar.
