About the FA-M3R The FA-M3R Range-free Multi-controller is a high-performance programmable logic controller (PLC) that combines very high processing speeds with stable control features. It has a compact design, can be configured with up to 8192 input/output points, and has numerous advanced modules that can be added on to support a wide variety of applications. With its open design, improved functions, and space-saving characteristics, the FA-M3R decreases total cost of ownership (TCO).

Feature:

a) Ultra-fast Processing Speed
-Scans up to 20K ladder program steps per millisecond, minimum scan time of 200μs. Sensor control function (constant scanning), fast input to output response time of 10μs and fast interrupt signal response time of 100μs.

b) Ultra-compact Size
-When configured with one CPU module and three I/O modules, the FA-M3 R is no larger than a postcard and can handle up to 192 I/O points.

c) Universal I/O Range
-Controls up to 8192 points and has up to 310K words program capacity for devices.
-With all the capabilities of a high-end PLC but at the price of a low- to mid-range PLC.
-In the 1000 - 2000 point system range, costs 1/3 to 1/2 less than competing models.

d) Outstanding Maintenance Support Functions
-Remote Operation Maintenance Engineering (OME) function via Ethernet or public phone line.
-Error log and user log diagnostics
-Sampling trace diagnostics
-Common I/O module design for all systems, regardless of I/O range

e) Multiple CPUs
-Tasks can be divided between multiple ladder CPUs
-BASIC CPU can be added on for improved data processing
-applications can be run by an AT-compatible CPU
