Remote Control With Commands; Additional Functions Of The Datalogger - Relay MR005DL User Manual

6 Remote control with commands

Function
In the inactive state the MR00xFA and MR00xDL work like simple level converter. The signals
of the RS232C and RS485 interfaces are converted to M-Bus signals and vice versa. The CPU
watches the data transmission and reacts on certain control frames. Following a successful
login command the device switches itself from level converter mode to command mode. Then
the device can directly be controlled with a PC or via modem using the RS232C interface. This
command mode includes reading single meters, downloading all stored data, configuration and
even an update of the software. The document "W60CMxxE.PDF" (xx = version) describes all
commands for development of adapted readout software. The following documentation
describes our software FService for configuration and remote control of MR00xDL and
MR00xFA.
Operation with modem
The M-Bus protocol uses an 11-bit format with very critical timing requirements. The modems
which are nowadays available on the market don´t support this format. Therefore we offer a
special solution called "M-Bus modem" for use with any level converter and also with
MR00xDL/FA in level converter mode.
In spite of this the command mode makes use of standard modems with 10-bit format. There
are two programs which support communication to MR00xDL/FA using commands: FService
and DokomCS (under preparation).

7 Additional functions of the Datalogger

Functionality
The Datalogger MR00xDL software offers a scheduler for time-triggered readout and storage of
M-Bus data. The scheduler distinguishes between two modes:
a) Readout in fixed periods from one minute to one week
b) Readout at fixed points of time (e.g. at end of each month)
On automatic readout the Datalogger reads all meters which are included in the list of slaves.
The first respond telegram after a SND_NKE + REQ_UD2 is stored together with the readout
time into the FLASH memory.
Selecting readout time
The readout time can be selected using the keyboard and LCD or by remote access with a PC
or via a modem. The following selections are possible via keyboard:
• 1, 2, 3, 5, 10, 15, 20, 30 minutes interval
• 1, 2, 3, 4, 6, 12 hours interval
• once per day, once per week, twice per week, once per month
• 4 times per year, 2 times per year and once per year
• 0 times per year = logging function deactivated
