A system from the MFW product family
Master module
In each central station one basic module of the master module version is used. The master module
coordinates the data exchange between the individual stations and has an image of all system inputs
and outputs. At the moment master modules are available with the following type names:
MF-... - standard telecontrol master
MD-... - telecontrol master with data logger function *
Substation module
The substation modules are used in the substations. At present, substation modules with the following
type names can be used:
UF-... - telecontrol substations
UD-... - standard version of the telecontrol substation with data logger function *
UL-... - low power version of the telecontrol substation with data logger function *
Expansion module
Each basic module can be fitted with up to a maximum of 15 expansion modules in order to increase
the I/O range. These are connected via the CAN bus interface.
I/O module
The majority of basic modules have 8 inputs or outputs. These are referred to as I/O modules. In the
same way, the expansion modules contain an I/O module consisting of 8 digital inputs, 8 transistor
outputs, 8 output relays, 4 analog inputs or 4 analog outputs.
Station address
To identify the stations in the MFW system, each substation module is given a station address (1 -31).
The master module is fixed to address 0. Station addresses must be unique.
Module number
Each I/O module is given a module number. The data is exchanged between modules with the same
module number. The physical arrangement of the modules within the system (the station address) is of
no significance at all here. The input module with number 5, for instance, transmits its data to all the
output modules whose number is 5.
* These modules are not available with 2 wire modem.
2.3 Safety instructions
These operating instructions must be carefully read and followed!
Risk of interference with electronic devices!
When operating the telecontrol system close to devices that are subject to interference, the
special regulations for these areas must be observed!
Risk of ignition from electromagnetic fields!
The MFW modules must not be operated in the neighbourhood of inflammable gases or
liquids (fuel depots, petrol stations, chemical works, gas containers etc.)!
Risk of damage!
The MFW modules must not be opened or subjected to improper modification!
