Memory & Expansion Capacity
The T1-16S is a micro PLC. But it has a large program and data memory.
♦
8192 Steps of Program Memory
♦
4096 Words of Data Registers, 256 Timers, & 256 Counters
♦
Discrete I/O 144 Points max
Execution Speed
Sophisticated machine control applications require high-speed data manipulation. The T1-16S is
designed to meet these requirements. The T1-16S is 8 times faster than Toshiba's earlier
M20/M40 PLCs.
designed to meet these requirements. The T1-16S is 8 times faster than Toshiba's earlier
M20/M40 PLCs.
Performance
The T1-16S offers 21 basic ladder instructions and 97 insert able function instructions.
Subroutines, Interrupt functions, Indirect addressing, For/Next loops, Increment/Decrement, Pre-
derivative PID, etc. are standard on the T1-16S. These functions allow the T1-16S to be applied
to the most complex and demanding control applications.

Main Unit + 8 I/O Modules
(Max Discrete I/O = 16 points + 8 x 16 points = 144 points)
(Max Analog I/O = 8 channels)
Any mix of discrete & analog modules maybe used.

< Scan time comparison between T1-16S and Toshiba's M40 >
Notes: 1. Actual results of the scan time for a 4K step test program (Including overhead).
The test program consists of:
- 50% of Sequence (Boolean and Timer) Instructions
- 30% of Data Transfer Instructions
- 20% of Arithmetic (Addition, Subtraction and Compare) Instructions
- 30% of Data Transfer Instructions
- 20% of Arithmetic (Addition, Subtraction and Compare) Instructions
2. The more data transfer & arithmetic instructions used, the faster the T1-16S becomes when
compared to other PLCs.
