5.2 Modbus master

For active dial-up to the Internet for alarms by e-mail, the device
modem must be switched into a different mode, using another INIT
string.
The telephone number, user name and password must be entered
so that they match the details for the selected Internet provider.
When the dial-up procedure to the Internet has been completed,
the modem will automatically be reset to the initial state, using the
INIT string that was entered in "Modem parameters".
If the JUMO Logoscreen nt has been configured as a master, (see Chapter 3.4
Configuration of the serial interfaces, page 12) it can send Modbus requests to
the slaves in the network (e.g. other recorders). The values that are requested
will be written to the external device variables of the Logoscreen nt:
- external analog values 1 to 24 in the analog selector
- external binary values 1 to 24 in the binary selector
