Level 2: Writing program is prohibited

Level 1: No protection (changing passwords is available only in this level)

Two points of solid-state output:

Each model of the T1/T1S has two points of solid-state output (transistors for DC input type and triacs for AC input type). These solid-state outputs are suitable for frequent switching application.

Removable terminal blocks:

The T1-28, T1-40 and T1-40S are equipped with removable terminal blocks. This supports the easy maintenance work.

DIN rail mounting:

The T1/T1S is equipped with brackets for mounting on a standard 35 mm DIN rail. The T1/T1S can be mounted on a DIN rail as well as screw mounting.

On-line program changes: (T1S only)

When the T1S’s memory mode is set to 4 k steps mode, on-line (in RUN mode) program changes are available. Furthermore, program writing into the built-in EEPROM is also available in RUN mode. These functions are useful in program debugging stage.

Real-time clock/calendar function: (T1S only)

The T1S has the real-time-clock/calendar function (year, month, day, day of the week, hours, minutes, seconds) that can be used for performing scheduled operations, data gathering with time stamps, etc. The real-time-clock/calendar data is backed up by built-in capacitor for power off. The back-up period is more than 7 days at 25 °C.

RS-485 multi-purpose communication port: (T1S only)

The T1S has an RS-485 multi-purpose communication port. Using this port, one of the following communication modes can be selected.

·Computer link mode: T-series computer link protocol can be used in this mode. Up to 32 T1Ss can be connected to a master computer. By using this mode, MMI/SCADA system can be easily configured.

·Data link mode: Two PLCs (any combination of T1S, T2E or T2N) can be directly linked together. This direct link is inexpensive, easily configured and requires no special programming.

·Free ASCII mode: User defined ASCII messages can be transmitted and received through this port. A terminal, printer, bar-code reader, or other serial ASCII device can be directly connected.
