About the Modicon M241 Logic Controller
M241 Logic Controller Description
The M241 Logic Controller has various powerful features and can service a wide range of applications.
Software configuration, programming, and commissioning is accomplished with the EcoStruxure Machine Expert software described in detail in the EcoStruxure Machine Expert Programming Guide and the M241 Logic Controller Programming Guide.
The M241 Logic Controller is configured and programmed with the EcoStruxure Machine Expert software, which supports the following IEC 61131-3 programming languages:
oST: Structured Text
oFBD: Function Block Diagram
oSFC: Sequential Function Chart
EcoStruxure Machine Expert software can also be used to program these controllers using CFC (Continuous Function Chart) language.
The power supply of the M241 Logic Controller is 24 Vdc or 100...240 Vac.
The M241 Logic Controller includes a Real Time Clock (RTC) system.
The M241 Logic Controller can be operated externally by the following:
oA hardware Run/Stop switch.
oA Run/Stop operation by a dedicated digital input, defined in the software configuration. For more information, refer to Configuration of Digital Inputs.
oAn EcoStruxure Machine Expert software command.

(1) The regular inputs have a maximum frequency of 1 kHz. (2) The fast inputs can be used either as regular inputs or as fast inputs for counting or event functions. (3) The fast transistor outputs can be used either as regular transistor outputs, as reflex outputs for counting function (HSC), or as fast transistor outputs for pulse generator functions (FreqGen / PTO / PWM). |
