Clear definitions, engineering boundaries and related concepts for HMI, PLC, servo, EtherCAT, Profinet and industrial communication.
FLEXEM is an industrial automation brand offering HMI, PLC, servo, motion control and industrial IoT products.
An HMI is an operator interface used to display machine status, enter parameters, manage alarms, recipes and production data.
A motion PLC combines sequence logic with axis control functions such as homing, positioning, synchronization, interpolation and electronic cam.
EtherCAT is a real-time industrial Ethernet technology commonly used for synchronized servo axes and distributed I/O.
Profinet is an industrial Ethernet system widely used in Siemens automation environments for controllers, drives, I/O and diagnostics.
Servo inertia ratio is the reflected load inertia divided by the motor rotor inertia and is an important indicator for tuning and dynamic response.
Panel cutout is the opening size required to mount an HMI or panel device in a control cabinet.
GSDML is the XML-based device description format used by Profinet engineering tools to identify and configure devices.
Electronic gear ratio defines the relationship between command units and motor or load movement in a servo positioning system.
Remote I/O places input and output modules near field devices and connects them to the controller through an industrial network.
Modbus is a widely used industrial communication protocol. RTU normally uses serial RS485, while TCP uses Ethernet.
STO is a drive safety function that prevents torque-producing energy from reaching the motor without necessarily disconnecting the main power supply.
