Discover the heart of communication in automation with Control Techniques UD71 Serial Communications. From installation to parameter intricacies, delve into UD71's role in seamless drive integration.
Installation:
Switch off the Unidrive and disconnect it from the supply for 15 minutes. Insert the Large Option Module, ensuring a correct connection. Utilize the appropriate connecting cable from Table 1 and connect it to the correct connector on the Large Option Module.
Hardware Connections:
Follow Table 1 for EIA RS485 communications port connections. The pin configurations for 4-wire and 2-wire modes are provided in detail.
Software Parameters:
Configure parameters such as Serial Address, Serial Mode, Baud Rate, Two Wire Mode, Serial Programmable Source/Destination, and Scale Factor. Understand the ranges and default settings for each parameter.
Serial Communications Modes:
Explore three modes: ANSI Mode, OUTPUT Mode, and INPUT Mode. ANSI Mode utilizes 4-wire EIA RS485 with the ANSI protocol. OUTPUT and INPUT Modes use high-speed binary protocols for continuous data transfer.
Parameter Description:
Understand parameters like Serial Address (11.23), Serial Mode (11.24), Baud Rate (11.25), Two Wire Mode (11.26), and Serial Programmable Source/Destination (11.27). Serial Scale Factor (11.28) allows data scaling in serial modes 1 or 2.
Control and Addressing:
Learn the addressing structure with Group Address and Unit Address. Control characters (EOT, ENQ, STX, etc.) facilitate drive communication. Group addressing enables commands to multiple units simultaneously.
Reading and Writing Data:
Reading involves sending structured messages and receiving corresponding data. Writing data requires a specific message structure, including Group Address, Unit Address, Menu, Parameter, Data, and Block Checksum. Understand the process of re-writing data for subsequent write messages.
Calculating Block Checksum (BCC):
Use the XOR function for BCC calculation. An example and QuickBasic program are provided for better understanding.
