Installation process
The ECL 310 will NOT automatically search for M-bus devices.
The M-bus addresses can either be set directly (PNU offset 0,
e.g. 6000) or the ECL 310 can search for devices via the
“SCAN” function.
Installation by setting the address directly
Adjust the address for all connected energy meters. (The
primary M-bus address must be used – in some M-bus devices
the address must be set).
Adjust the type if needed.
Adjust the scan time if needed.
Done.
Installation by SCAN function
Set Command to SCAN.
Wait until all energy meters are found. This can be observed
in the Address fields for the respective energy meters.
When all energy meters have been found, the SCAN function
can be ended by setting the Command to INIT. Alternatively
wait for the SCAN function to end automatically – this takes
about 12 minutes.
Adjust the type if needed.
Adjust the scan time if needed.
When an energy meter address or type is changed, the M-bus
performs a (re-)initialization, where M-bus values are reset.
Values will appear again when the state is in IDLE.

System information parameters
The system information parameters include information
about types and versions. The parameters can be found in the
parameter list in the appendix. Only the ones with a special
encoding/decoding are described here.
Hardware no.
PNU 34 holds the hardware revision number. It is returned as
a 2-byte number where the first byte is the major version
number and the second byte is the minor version number.
For example the decimal number 16642 is returned:
The hardware revision number is then found as the first byte
as Unicode I hexadecimal format.
Unicode 0x41 corresponds to A, Unicode 0x42 corresponds to
B, and Unicode 0x43 corresponds to C etc.
The controller from the example is consequently a revision
A 2 hardware.
