Technical Manual Stage Controller MSR eco 3140 Page 14
The scheme beside shows briefly, how the dataline
wiring of several controllers via the 'network/line'
interface is made. At each controller, the shield has
to be connected to the nearest ground terminal
(PE). Also the ground connector of the controller
(term.1) and terminal #24 must be connected to
the nearest ground terminal.
This will assure good interference suppression,
even for long datalines between the controllers.
The MSR eco can be used as a Central Unit for
up to 64 Cold Storage Controllers of the series
EVP and TKP. These can be connected via a
separate network interface.
Shielding must be connected to the nearest ground
terminal. Also the ground connector of the controller
(term.1) and terminal #24 must be connected to
the nearest ground terminal.
Each connected controller gets an individual
address, which must be set at the controller and
on the Address Page (A) under A00...A63 .
Thus, data can be centralized and forwarded for
optimization of the control functions.
On the ‚Address Page‘, the controller ‚type‘
must be selected via ‚ d01 ‘ for each address, as
well as the influence on the suction pressure
shifting of the MSR eco via ‚ d02 and d03 ‘ for
each address.
Connection of Cold Storage Controllers as Slaves
Wiring of data lines (Network Line)
Networking of controllers via E-LINK
The MSR
eco
can be networked together with
other ELREHA control devices via an RS-485-2-
wire databus, which enables up to 78 controllers
to communicate. For communication, the
E-LINK
transmission protocol is used.
Each controller in a network has its individual
address (' P90 ', Mode Page).
!! Never use address 64 !!
The data transmission rate is factory set to "96"
(9600 Baud) and can also be set manually (" P89 ",
Mode Page).
If the MSR
eco
is not connected to a network, these
parameters are of no importance.
Remote control at Frontend Systems
The MSR
eco
controller can be operated remotely
via interface when it is connected to Frontend
Systems such as an SMZ.
In this case, the Frontend System shows the display
contents and the keys of the frontend work as if
they where the keys of the MSR
eco
.
Configuration / Service via PC
The controller can be linked to a PC via its RS-485
interface. By using the PC-software „Coolvision-
MES“, parameters can be changed, they can be
saved to the hard disk (download) and can be sent
to the controllers (upload).
To do this, the PC must be equipped with an RS-
485 interface (internal card or a converter of the
SSC-series).
