3 Intended use
The freely programmable controllers of the "ecomatController" series are rated for use under difficult
conditions: this includes an extended temperature range, strong vibration, intensive EMC interference.
This is a class A product. This product may cause radio interference in domestic areas.
u
If required, take appropriate EMC screening measures.
•
Safety controller for mobile machinery applications.
•
Two separately programmable controllers:
– safety PLC for safety-related applications
– standard PLC for standard applications
– CODESYS V3.5 programming system (in a version approved by ifm) for both controllers. The
safe controller requires a safety SIL 2 extension for CODESYS.
•
For applications operating according to the normally closed principle, for which the safety functions
can be implemented, the following applies: safe state = power-free state (power-free output,
switched off).
•
For a suitable time interval for the execution of the self-test of the controller, refer to the safety
concept or the applicable product standards of the application. If no value can be determined, it is
strongly recommended to restart the device after 7 days at the latest (see programming manual,
chapter Safety concept).
•
For the supply of the controller (on-board system, PELV power supply): (
•
Multifunctional inputs and outputs the operating mode (e.g. current, voltage, frequency input; PWM,
digital output) and use of which can be configured in one of the controllers.
•
Sensors and actuators can (depending on the required input and/or output type) be connected
either as single or dual channel and be used as a safe device.
•
Connection of sensors or actuators via CAN interfaces. Connection to other controllers via CAN.
Implementation of safe communication via CANopen Safety.
•
Only use the unit within the limits of the technical data: (
