3.1
Each NTXS communicates with one or two devices over its serial ports to get the information required by the
operator. ‘PLC’ term is used for any device mainly PLC / controller / Inverter. Information could be the value of
a PLC register or the status of a PLC coil / bit. This information is displayed on the LCD display of the unit. If
required, NTXS can also change the values of PLC registers / coils. Supported PLC’s list is shown in the
Network Configuration window of the Setup Software.
3.2
Microsoft Windows® based configuration software, NT-XS , configures the NTXS units. ‘Configuration’
means making the NTXS unit work as per the system requirements. For example, NTXS can be configured
to be used with PLC, display register data read from the PLC, perform key action to edit PLC data. The
complete configuration for a unit is termed as ‘Application’. Application comprises of Tag Data base,
Screens, Key Definitions, Alarms and Tasks.
Each register in the PLC memory has a unique address and can be identified by giving a specific name to
it. This information is stored as Tag Data Base in NT-XS Setup Software. Any coil or register to be used in
the application is known as a Tag and must be first defined in the Tag data base.
The LCD display on the NTXS unit displays the PLC data on a ‘Screen’. PLC data can be arranged on a
screen using different objects.
Operator can control the process by actually changing the value of PLC registers. This is possible with the
help of the Touch Screen keys. Different tasks can be assigned to keys on the NTXS keypad.
Any register can be constantly monitored if alarms are defined for it. When alarm condition is reached, the
respective alarm is displayed on the screen.
Once the application is defined, firmware for the specific unit and PLC is downloaded and then application
is downloaded into the unit. NTXS can now communicate with a PLC. To download application / firmware,
connect appropriate programming cable to Serial port of NT2S models. Setup can be downloaded on any one
of the ports of NT3S models.
3.3
NTXS can communicate with a PLC without any change in the NTXS hardware. To communicate with a
PLC, NTXS unit needs:
1. Communication Driver for the PLC:
Each PLC has a defined protocol for communicating with any device. Communication Driver is downloaded in
to NTXS unit along with the firmware. Communication driver varies from PLC to PLC. This driver enables
the unit to talk to a specific PLC, such as Omron PLCs.
2. NTXS - PLC Communication Cable: Proper NTXS - PLC cable is required for error free communication
with PLC. Please refer to the table given on next page for details on cables for different models.
