2Features
Z-TWS4, Z-PASS2-S and S6001-RTU are programmable, communication oriented PLCs.
The Z-TWS4/Z-PASS2-S/S6001-RTU StratON™PLC is programmable according to the IEC 61131-3 standard, by means
of the StratON development environment.
All three devices provide the following features:
OpenVPN connectivity
full configuration by means of an integrated web site
FW upgrade, that can be performed locally, by means of a USB pen, or remotely, through the web site
Z-PASS2-S and S6001-RTU integrate a 3G HSPA modem.
S6001-RTU is equipped with a rich set of analog and digital inputs/outputs.
Z-PASS2-S, S6001-RTU and Z-TWS4 (when connected to an external modem) can be used as a Router, routing packets
between the WAN (Mobile Network) and the LAN (Ethernet).
All three devices are based on a 32bits ARM9 processor, equipped with the Linux operating system (Linux kernel
2.6.28).
Z-PASS2-S-R01 is a new version of the Z-PASS2-S product, providing the following new features:
the two available Ethernet ports can be configured as two fully separated network interfaces (“LAN” and
“WAN”), whereas in the older versions they could only work as ports of an Ethernet switch; the user can
choose if the two ports shall work in “LAN/WAN” mode or “Switch” mode, by means of a new configuration
parameter (“Ethernet Mode”);
there are 4 more LEDs, providing information about the “Ethernet Mode” and the VPN functionalities.
Z-TWS4-IO is a new version of the Z-TWS4 product, providing the following new features:
one digital input which can be used to disable remote connection to the device
one digital output which goes HIGH when the device is remotely accessed
one digital output which can also be used as a remote command
one configurable digital input/output, which can also be used as a local alarm
a new set of LEDs
COM1 RS232/RS485 mode set by software (configuration parameter), instead of HW DIP switch
Z-PASS2-S-IO is a new version of the Z-PASS2-S product, providing the following new features:
one digital input which can be used to disable remote connection to the device
one digital output which goes HIGH when the device is remotely accessed
one digital input which can also be used as a local alarm
one digital output which can also be used as a remote command
two configurable digital inputs/outputs
a new set of LEDs
COM1 RS232/RS485 mode set by software (configuration parameter), instead of HW DIP switch
a new penta-band 3G+ modem, which also features a GPS module
Z-PASS2-S-IO-4G is a new version of the Z-PASS2-S-IO product, providing a new 4G LTE Cat.1 modem, instead of the
3G+ modem.

4Electrical Connections
4.1 Z-TWS4, Z-TWS4-IO, Z-PASS2-S, Z-PASS2-S-R01, Z-PASS2-S-IO
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 for Z-TWS4, Z-PC-DINAL2-52.5-17 for Z-PASS2-S. The following picture shows the
meaning of the IDC10 connector pins.
Power supply is available only from the rear connector for Z-TWS4, while:
Z-TWS4-IO can be powered also through 17-18 screw terminals;
Z-PASS2-S/ZPASS2-S-R01/ZPASS2-S-IO can be powered also through 14-15 screw terminals.
If Z-PC-DINAL1-35 or Z-PC-DINAL2-52.5-17 accessory is used, the power supply signals and communication signals may
be provided by the terminals block into the DIN rail support. In the following figure the meaning and the position of
the terminal blocks are shown. The DIP-switch that sets the 120 Ω terminator is used only for CAN communication (Z-
TWS4 only).
GNDSHLD: shield to protect the connection cables against interference (recommended).
The Device has two RS 485 serial ports for Modbus communication: COM 4 and COM 2. The RS485 connection for
COM 2 can be set up by means of the corresponding screw terminals or by the IDC10 connector. On Z-TWS4, to select
RS 485 on IDC10 connector, put the SW1 DIP-switch on OFF position; on Z-PASS2-S, no operation is needed.

USER MANUAL –Z-TWS4/Z-PASS2-S/S6001-RTU
17
The Z-TWS4 has a CAN port available on screw terminals 10-11-12. As an alternative, the connection can be set up on
the IDC10 connector. To select CAN port on IDC10 connector, put the SW1 DIP-switch on ON position.
Through a removable 4 pin connector, the Device provides a serial RS232 port or, as an alternative, a third RS485 port.
In order to select the RS232 port on the removable 4 pin connector, put the SW2 DIP-switch on ON position; to select
the RS485 port on the removable 4 pin connector, put the SW2 DIP-switch on OFF position
2
.
In Z-TWS4-IO/Z-PASS2-S-IO, the mode (RS485/RS232) of this port is set as a parameter in software configuration.
The cable length for the RS232 interface must be less than 3 meters.
2
While in Z-TWS4 the SW2 DIP-switch position can be changed by the user, in Z-PASS2-S the DIP-switch is internal and
its position is permanently set in the factory.

The Device has a USB HOST type A connector, that can be used as an additional serial port (using a Seneca S117P1, for
example) or to connect an external USB memory; this is used for FW upgrade (see chapter 17).
Please note that, on this USB port, the “hotplug” feature is not available; so, after plugging the USB device, it is
necessary to power off/on the Z-TWS4/Z-PASS2-S to let it detect the USB device.
The Z-TWS4 also has a second USB HOST connector, with micro-USB plug-in, that can be used to connect a USB device
by means of a “Micro USB to USB” adapter; this port is no more available in Z-TWS4-IO.

The Device has two Ethernet ports with RJ45 connectors on the front panel. The two ports are internally connected in
HUB/SWITCH mode. The two ports have the same MAC Address.
The Device has a plug-in connector for micro SD card placed in the side part of the case.
To insert the SD card into the connector, be sure that the SD card is oriented with metal contacts facing towards left
(with reference to the figure).
The SD card can be of any class.
The Z-PASS2-S has a slot for SIM card, placed on the side of the case. Before pushing the SIM card into this slot, please
be sure that the SIM card golden contacts are facing towards right (please see the figure below).
