The M262 Logic/Motion Controller can be operated externally by the following:
oA hardware Run/Stop switch.
oAn EcoStruxure Machine Expert software command.
oA 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.
oThe system variable PLC_W in a Relocation Table.
oThe Web server.
The M262 Logic/Motion Controller has a hardware Run/Stop switch, which puts the controller in the RUN or STOP state.
