2.4 Readng Data from a Modbus Devce and
Transferrng the Data as the Montor Server
When you run the executable function, data is read in from the Modbus devices, the PC
becomes the monitor server, and data is transferred to DAQLOGGER or Remote Monitor.
The executable function can be run as a process or a service. When run as a process,
the executable function closes when logging off Windows. When run as a service, the
executable function is registered in Windows as an automatically executable service.
When run as a service, the executable function continues processing even when the
user has logged off of Windows. Also, the executable function is run automatically as
soon as the PC is turned ON (prior to log in). However, the software can only be run as a
service by a user with Administrator privileges. Services cannot be executed when using
Windows Vista.
Note
The maximum number of DAQLOGGERs or Remote Monitors that can be connected at once is
16.
