Run/Stop

Overview

The M262 Logic/Motion Controller can be operated externally by the following:

A hardware Run/Stop switch.
An EcoStruxure Machine Expert software command.
A Run/Stop operation triggered by an embedded digital input. The digital input is defined in the software configuration. For more information, refer to the M262 Logic/Motion Controller Programming Guide.
The system variable PLC_W in a Relocation Table.
The Web server.

The M262 Logic/Motion Controller has a hardware Run/Stop switch, which puts the controller in the RUNNING or STOPPED state.

The interaction of the 2 external operators on the controller state behavior is summarized in the table below:

		Embedded hardware Run/Stop switch
		Switch on Stop	Stop to Run transition	Switch on Run
