The 5069-L4100ERMW controller is a CompactLogix 5480 controller used for a variety of applications which include integration with different I/O modules over an EtherNet/IP network. The 5069-L4100ERMW controller by Allen-Bradley/Rockwell Automation has a maximum MOD power of 72 Watts and a MOD power voltage range of 18 to 32 Volts DC. It is part of the CompactLogix 5480 series.

Before the advent of secure networks, hard-wired safety relays used simplified logic to implement basic safety functions. “The inputs and outputs are directly connected to the security system and processed. Greene said: “This approach is very effective when the machine has a small footprint or a small number of security inputs.

Secure networks can now connect various security components via Ethernet or other industrial communication protocols. “By placing the I/O modules closer to the object being monitored, overall wiring can be reduced,” Greene said. “The safety logic only comes into play when there is a safety failure, such as when the protective door is opened during normal operation or when the motor is out of its permitted speed range.”

The code designer simplifies how the system handles failures that have identified risks in the process and writes code to perform appropriate safety functions. “In the IEC 61131 standard, common functional blocks can be written and shared across many machines where similar security risks can occur,” Greene added.
