984 Compact SERIES

The Modicon 984 Compact series of PLCs brought the high performance, application flexibility, and programming compatibility of the 984 family to the small controller market. As a controller in the 984 family, Compacts implement a common instruction set for developing user logic, standard Modbus communication functionality, and optional Modbus Plus communication capabilities.
Modicon TSX Compact supports the SCADA industry trend towards open, PLC based, RTU platforms rather than proprietary hardware and protocols. Compact controllers may be programmed in either traditional 984 relay ladder logic or in the 5 languages of the international IEC 1131-3 standard supported by Schneider Automation’s award winning Concept programming software inclusive of ladder, SFC, function block, structured text and instruction list.
The Compact Controllers shared the 984 processing architecture.
This architectural consistency allowed the The Modicon 984 Family of PLCs to achieve machine compatibility with the other controllers in the family. This allows sequences of user logic created on a mid-range or high performance controller, such as a 984B or a 984-685 Controller,-to be relocated to a Compact. It also assures that user logic generated for this small controller is upwardly compatible to larger 984(s). Thus, a Compact can be easily integrated into a multi-controller network.
