Allen-Bradley Communications Features

The Allen-Bradley Communications enabler:

  • Provides the following features:
  • Configuration functions for defining the logical communication ports used by CIMPLICITY software for the device interface. A device communications process is attached to each port, and up to four communication processes can be configured for a CIMPLICITY computer.
  • Configuration functions for defining the devices accessed via each communication port and the data or "points" to be exchanged.
  • Asynchronous exchange of data between CIMPLICITY software and a variety of devices.
  • Support for collecting data from the Allen­Bradley processors via unsolicited data messages.
  • Alarm generation when a communication failure occurs.

A utility program for Ethernet communications, abiping.exe , which is used for validating the network addresses that must be specified for each device to which communications are to be established.

  • Supports the following CIMPLICITY features:
  • Polled reads at user defined rates
  • Poll after setpoint
  • Triggered reads
  • Analog deadband
  • Alarm on communications failure
  • Server Redundancy configurations
  • Supports the following data types:
  • Signed 8, 16, and 32 bit integer
  • Unsigned 8, 16, and 32 bit integers
  • Text
  • Arrays
  • Floats (for most supported device types).
