DC541-CM Interrupt and Counter Module

The Function Module DC541-CM can be used for a wide variety of control tasks. It can be configured to act for example as an interrupt I/O, as a fast counter or to provide pulse width modulation functionality.

Configuration in Automation_Builder is mainly identical, however, programming with the provided Function Blocks differ. All neccessary Function Blocks for DC541-CM programming are available in the DC541_AC500_V11.lib: DC541 Library

Details on the hardware is provided in the device descriptions DC541 Hardware: Digital Input/Output Module DC541-CM
