1. System Configuration

Memory capacity:

Program memory capacity of the T1 is 2 k steps. And that of the T1S is 8 k steps. Whole the program and a part of data registers are stored in built-in EEPROM.

	T1		T1S
Memory	RAM (for execution) and EEPROM (for back-up)
Program capacity	2 k steps		8 k steps
			(4 k mode or 8 k mode)
Data capacity	Auxiliary relay: 1024 points		Auxiliary relay: 4096 points
	Timer:	64 points	Timer:	256 points
	Counter:	64 points	Counter:	256 points
	Data register:	1024 words	Data register:	4096 words
EEPROM back-up	Program and leading 512 words		Program and the user specified
	of Data register		range of Data register (0 to
			2048 words)
RAM back-up	Capacitor		Capacitor
	(6 hours or more at 25°C)		(168 hours or more at 25°C)

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.

	T1		T1S

calendar			hours, minutes, seconds)
Communication	RS-232C (programmer port)		RS-232C (programmer port),
			RS-485 (multi-purpose)

Construction:

The T1/T1S is a compact, easy-handling block style programmable controller. The T1/T1S has all of the features of a block style controller. In addition, the T1-40/T1-40S has modular expandability. The T1-40/T1-40S provides flexibility into the block style controller.

Series compatibility:

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.
