Note
The outputs may only be switched parallel within
a group (Q1 to Q4 or Q5 to Q8, S1 to S4 or S5 to
S8) ; e.g. Q1 and Q3 or Q5, Q7 and Q8. Parallel
switched outputs must be similtaneously
energised.

Note
• Analogue signals are more sensitive to
interferance than digital signals, therefore the
signal conductors should be carefully routed.
Inappropriate connections can lead to
unwanted switching conditions.
• Analogue output 0 to 10 V, Resolution 10 Bit,

Expansion of the input and output points for easy and MFD-Titan
To expand the input and output points there are
various solutions :
Central expansion, to 40 I/O
easy700, easy800 and MFD-Titan can be
expanded via easy202, easy618 or easy620. Here
there are a maximum of 24 inputs and 16 outputs
available. An expansion of the basic device is
possible.
Decentral expansion, to 40 I/O
easy700, easy800 and MFD-Titan can be
expanded via the coupling module easy200-EASY
with easy618 or easy620. The expansion device
can be operated up to 30 m from the basic device.
There are a maximum of 24 inputs and 16 outputs
available. An expansion of the basic device is
possible.
Networking via EASY-Net, up to 320 I/O
When expanding the inputs and outputs via
EASY-Net eight easy800 or MFD-Titan can be
connected to each other. Every easy800 or
MFD-Titan can be extended with an expansion
device. 1000 m Network length is possible. There
are two types of operation:
• One master (position 1, device address 1) plus
up to 7 further devices. The programme is in the
master.
• One master (position 1, device address 1) plus
up to 7 further “intelligent” or
“non-intellegent” devices. Every “intelligent”
device has a programme.

Example 1 Example 2
1) The geographic location/place 1 always has the
device address 1.
• Addressing the devices:
– Automatic addressing of device 1 or via
EASY-SOFT… by PC, geographic location =
device,
– Single addressing on the corresponding device or
via EASY-SOFT… on each device, geographic
location and device can be different.
• The max. total length with EASY-NET is 1000 m.
• Should EASY-NET be interrupted or a device is not
operational, the network isn´t active past the
interrupted point.
• 4 core cable unscreened, each two cores twisted.
Characteristic impedance of the cable must be
120 O.

• Addressing the devices:
– Single addressing on corresponding device or via

• The max. total length, including spur cables, with
EASY-NET is 1000 m.
• The max. length of T pieces to easy800 or to
MFD-Titan is 0,30 m.
• Should EASY-NET be interrupted between the T
piece and the device, or a device is not operational,
the network is still active to any further device.
• 4 core cable unscreened, each two cores twisted.
Three cores are required.

Configuration of the network cable for
EASY-NET
The network cable does not need to be screened.
The characteristic impedance of the cable must be
120 O.
Note
The minimal operation with easy-NET functions
with the conductors ECAN_H, ECAN_L, GND. The
SEL_IN conductor is solely for automatic
addressing.
Bus terminal resistor
A bus terminal resistor must be connected to the
geographical first and last device in the network:
• Value of the bus terminal resistor 124 O,
• Connect to PIN 1 and PIN 2 of the RJ-45 plug,
• Connection plug : EASY-NT-R.

Calculation of cross section when conductor
length is known
The minimum cross section is calculated for the
know maximum use of the network.
Note
When the result of the calculation doesn´t give a
normal cross section use the next highest normal
cross section.
Calculation of conductor length when the
