B - REMOTE COMMUNICATION

11.2.1 Conguring of the Serial Link

The I/O group contains the parameters that govern the baud rate, watchdog timer, and protocol selection for

the serial interface. (I/O 46 to I/O 50)

All addresses from 1 to 247 are allowed for RSi S4 drives. Address 0 is a broadcast address understood by

all drives; however, no reply is returned for messages sent to this address.

11.2.2 Parameter Addresses

Each parameter is assigned a unique memory address to permit easy reading and conguration. Chapter 6

and 7 lists all RSi S4 parameters and the memory address assigned to each under the Modbus heading.

11.2.3 RSi S4 VFDs

RSi S4 VFDs can be controlled remotely via Modbus in the standard product, and via other eldbusses with

optional communications cards. The bits in Control Word 1 and Control Word 2 are used to control various

aspects of the drive’s operation, and the bits in Status Word 1 and Status Word 2 are used to communicate

drive status back to the controlling computer.
