Introduction
OIS60 is an Operator Interface for PLCs. It communicates with a PLC over its serial communication port
to get the information required by the operator. Information could be the value of a PLC register or the
status of a PLC coil. This information is displayed on the LCD display of unit. If required, OIS60 can also
change the values of PLC registers / coils.

Application - Tags, Screens, Touch Screen keys and Tasks
Microsoft Windows® based configuration software, OISetup32, configures the OIS60. ‘Configuration’
means making the OIS60 unit work as per the system requirements, example. OIS60 can be configured
to be used with any PLC, display any register data, perform any action using a key. The complete con-
figuration 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 OISetup32. 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 OIS60 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 OIS60 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 applica-
tion is downloaded into the unit. OIS60 can now communicate with a PLC.

PLC Communications
OIS60 can communicate with any PLC without any change in the OIS60 hardware. To communicate with
a PLC, OIS60 unit needs:
1. Proper Communication Driver for the PLC
2. OIS60 - PLC communication cable
1. Communication Driver for the PLC:
Each PLC has a defined protocol for communicating with any device. Communication Driver is down
loaded in to OIS60 unit along with the firmware. Communication driver varies from PLC to PLC. This
driver enables unit to talk to a specific PLC, such as a Toshiba T1 PLC.
2. OIS60 - PLC Communication Cable: Proper OIS60 - PLC cable is required for error free
communication with any PLC.
