MODBUS and CANOPEN connection standards
1) Install the module into the DIN rail.
2) Please use a cable with a suitable length to connect the remote modules.
The following table show the cables length.
- Bus Length: Modbus network maximum length as a function of the Baud rate.
This is the length of the cables which connect the two bus terminators modules.
- Derivation Length: Derivation line Maximum length as a function of the Baud Rate
(see Scheme 1).
In order to obtain maximum performances it’s recommended to use a specific shielded
cable, as an example BELDEN 9841.

Installation Rules
The module is designed to be installed, in vertical position, on rail. In DIN IEC EN 60715
order to ensure optimum performance and a longest working life, the module(s) must be
provided with adequate ventilation and no raceways or other objects that obstruct the
ventilation slots. Never install the modules near heat sources.
We recommend installation in the lower part of the control panel.
Inserting on the DIN rail
As the picture shows:
1) Insert the module rear IDC10 connector
on a DIN rail free slot (there’s only one
way to insert the module because of
polarized connector).
2) Push the two locks placed at the sides
of the rear IDC10 connector to fix the
module.

Electrical Connections
Power supply, MODBUS and CAN interface
Power Supply and Modbus interface are available by using the bus for the Seneca
DIN rail, by the rear IDC10 connector or by Z-PC-DINAL1-35 accessory.
Z-PC-DINAL 1-35 Possible Use
If Z-PC-DINAL1-35 accessory is used, the
power supply signals and communication
signals may be provided by the terminals
block into the DIN rail support. The figure
shows the meaning and the position of the
terminal blocks. The DIP-switch that set
the 120 Ω terminator is used only for CAN
communication.
GNDSHLD: Shield to protect the
connection cables against interference
(recommended).
RS485 COM 2 and RS485 COM 4 Ports
The Z-TWS5 has two serial ports RS 485:
COM2 and COM4.
The RS485 COM2 port can be connected
through corresponding screw terminals or
by IDC10 connector.
To select RS 485 on the IDC10 connector,
switch the SW1 to OFF position.
CANopen Port
The Z-TWS5 has a RS485 COM3 isolated
port available at screw terminals 10-11-12.

Other Z-TWS5 Ports
USB #1 HOST Port
The Z-TWS5 has a USB HOST type A
connector, that can be used as
additional serial port (using a Seneca
S117P1, for example) or to connect an
external USB memory.
USB #1 HOST
321
USB #2 On The Go Port
The Z-TWS5 has a USB On The Go
connector, with micro-USB plug-in, that
can be used as Ethernet connection for
Samba (through a driver before installed
on PC). The MAC ID of this port is
different than the MAC ID of the two
Ethernet ports on the front panel.

Ethernet RJ45 ports (frontal panel)
The Z-TWS5 has two ethernet ports,
with RJ45 connector, on front panel, for
easy PC connection.
The two ports are internally connected
in HUB/SWITCH modality.
The two ports have the same MAC ID.
RS232 or RS485 COM1 Port
The Z-TWS5 on miniB connector, has a
serial RS232 COM1 port or, as an
alternative, has a third RS485 COM1
port.
In order to select the RS232 port or the
RS485 port you can use the Z-TWS5
configuration software.
The cable length for the RS232 interface
must be less than 3 meters.
