DH+ Configuration
When you configure a communications channel for DH+
communications, the PLC Communications Adapter Board becomes
a station on the DH+ link. You can pass information to and from the
drive using the DH+ protocol.
When configured for DH+ communications, the PLC
Communications Adapter Board can:
•
Support 57.6K, 115K, or 230K baud communication rates.
•
Support read or write messages for blocks of parameters.
•
Allow the PLC to to issue 1336 FORCE messages using a method
similar to RIO block transfer.
The terminating resistors (R1 and R2 in the figure below) depend on
the baud rate:
If you are using this baud rate:
Then, you need to use this
terminating resistor:
57.6K 150 Ohm
115K 150 Ohm
230K 82 Ohm
The following is the wiring configuration necessary for DH+:
