OUTPUT
Output 1: 40002.0
Output 2: 40002.1
Output 3: 40002.2
Output 4: 40002.3
Output 5: 40002.4
The active status of the output is obtained by setting the bits
to 1.
DIGITAL OUTPUTS
In the Modbus register 40002 is possible to see or change the state of the outputs.
Bits 0 to 4 in 40002 register respectively represent the status of outputs from 1 to 5.
Besides
you can set up the outputs in a state of security when the bus communication
is lost.
Note
: when switches from 3 to 8 are in OFF, comunication settings are retrieved from
EEprom).
2nd Note:
The termination of the RS485 line must be carried out only at the ends of the
communication line.
DIP-SWITCH SETTINGS
Before switching the DIP switches, disconnect the power supply in order to avoid
damage to the module.
The DIP-switches position defines the module Modbus
communication parameters: Address and Baud Rate. In the following figure the Baud Rate
and Address values are listed as a function of the DIP-switches position:

NOTE
: For the best performances, the use of special shielded cables is recommended
(BELDEN 9841 cable for example).

MODBUS CONNECTION RULES
1) Install the modules on the DIN rail (max 120).
2) Connect the remote modules using cables of proper length.
On the table the following data about the cables length are provided:
-Bus Length: Modbus network maximum length as a function of the Baud rate. It is the
lenght of the cables which connect the two bus terminators modules (see Scheme 1).
-Drop Length: maximum length of a drop line (see Scheme 1) as a function of the Baud
Rate.
MODBUS RS485
Connection for RS485 communication using the Modbus master
system as an alternative to the Z-PC-DINx bus.
Note: the indication of the RS485 connection polarity is not
standardised and in some masters may be inverted

5 B (-)
6 A (+)

Note
: Pay attention to the maximum current that can flow
through the relays common terminal. Please see the

Power Supply
Terminals 2 and 3 can be used to provide the module with power
supply as an alternative to connection using the Z-PC-DINx bus.
The upper limits mus not be exceeded as this can seriously
damage the module.
If the power supply source is not protected against overload, a safety
fuse with a max. permissible value of 2.5 A must be installed in the
power supply line.
