Parker 590+ series - EI Bisynch ASCII Support; Features

A-8 Serial Communications
DC590+ Series DC Digital Drive
EI Bisynch ASCII Support
The drive can communicate using the EI Bisynch ASCII protocol without the need for a Technology Option board to be fitted.
NOTE The P3 port is not physically compatible with a multi-point network.
This communications protocol comes under the heading of Binary Synchronous Communications Data Link Control (BSCDLC). This is all part of an
internationally recognised ANSI standard protocol called BISYNCH (Binary Synchronous) and is known by the abbreviation x3.28. It is widely used
by manufacturers of computers, computer peripherals, and communications equipment.
EI BISYNCH, the specific form of communication used, corresponds with the following full American National Standard definition:
• ANSI Standard: x3.28, Revision: 1976
• Establishment and Termination Control Procedures Sub-category 2.5:
Two-way Alternate, Non-switched Multi-point with Centralised Operation & Fast Select
• Message Transfer Control Procedure Sub-category B1:
Message Associated Blocking with Longitudinal Checking & Single Acknowledgement
This is known by the abbreviation ANSI - x3.28 - 2.5 - B1.
Features
• Configured using Function Block inputs
• Diagnostics using Function Block outputs
• Software-selectable Baud Rate
• Software-selectable Slave Address
• Direct tag access for all parameters
