Control functions:
In addition to the basic relay ladder functions, the T1/T1S provides functions such as
data operations, arithmetic operations, various functions, etc. Furthermore, its high-
speed counter functions, pulse output functions and data communication functions
allow its application to a wide scope of control systems.

Construction:
The T1-16S is a compact, easy-handling block style programmable controller. The
T1-16S has all of the features of a block style controller. In addition, the T1-16S has
modular expandability. The T1-16S provides flexibility into the block style controller.
Series compat ibility:
Programming instructions are upward compatible in the T-Series programmable
controllers. The T1/T1S programs can be used for other models of the T-Series, T2,
T2E, T2N, T3 and T3H. Peripheral tools can also be shared.
