The BMXNOC0401 Ethernet communication module can support up to 128 connections to remote devices. The health of each connection is represented in a single bit value. A health bit value of:
1 indicates the connection is active
0 indicates the connection is inactive
A Derived Data Type variable is automatically created when you add a BMXNOC0401 module to your project.
You can use this DDT variable to view the state of each connection to remote EtherNet/IP and Modbus TCP devices.
Health is displayed in the form of a HEALTH_BIT array consisting of 32 bytes with each connection represented by a single bit.
- a bit value of 1 indicates the connection is healthy
- a bit value of 0 indicates the connection is lost, or the module can no longer communicate with the remote device
