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
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
Floats (for most supported device types).
