M262 Logic/Motion Controller Description
Overview
The M262 Logic/Motion Controller has various powerful features and can service a wide range of applications.
Programming Languages
The M262 Logic/Motion Controller is configured and programmed with the EcoStruxure Machine Expert software, which supports the following IEC 61131-3 programming languages:
-
IL: Instruction List
-
ST: Structured Text
-
FBD: Function Block Diagram
-
SFC: Sequential Function Chart
-
LD: Ladder Diagram
EcoStruxure Machine Expert software can also be used to program these controllers using CFC (Continuous Function Chart) language.
Real Time Clock
The M262 Logic/Motion Controller includes a Real Time Clock (RTC) system.
The system time is maintained by capacitors when the power is off. The time is maintained for 1 000 hours when the controller is not supplied.
Run/Stop
The M262 Logic/Motion Controller can be operated by the following:
-
A hardware Run/Stop switch.
-
A Run/Stop operation by a dedicated digital input, defined in the software configuration. For more information, refer to Configuration of Digital Inputs.
-
An EcoStruxure Machine Expert software command.
-
The system variable PLC_W in a Relocation Table.
-
The Web Server.
