Loop Control Module (L1)

This module has loop control functions.

Up to 8 loops can be controlled.

Capable of controlling up to 8 loops with a program capacity of 6k steps on the shortest loop cycle of 50 ms.

Hyper PID installed

Toshiba's exclusive 2-degree-of-freedom hyper PID is installed for high-precision loop control in a broad range of applications, including boiler control and combustion control.

Sequence control also available

The international standard IEC61131-3 is employed as programming language so that the L1 module may be used for not only loop control but also sequence control and batch control.

Functions as a one-loop controller

The series supports I/O modules (LP01/LP02) equipped with I/O points corresponding to TOSDIC-215D to permit use as a one-loop controller.

Connectable to TOSDIC-CIE series

Tag meter variables used in the Integrated Controller system TOSDIC-CIE are available. Connection to OIS-DS SMART serving as HMI through an Ethernet permits OIS display and setting.

Computer link port provided

An RS-485 port is provided for communication with a graphic panel or higher-level computer through a computer link.

15 kinds of I/O - loop, analog, digital, pulse, etc. - are available. I/O modules can be connected to the terminal unit and DIN rails so that there is no need for useless spaces. (16 modules maximum) I/O modules may be placed as desired within a range of 1 km, and be expanded to flexibly meet your needs.

I/O modules different in IO bus rate cannot be mixedly used.
