Using RTU Master Mode
Appendix D provides information about using the 1203-USB converter in RTU Master
mode.
With the converter in RTU Master mode, you can monitor, configure, and control up to
32 MDI Class drives using one of the Reliance Electric drive software tools.
Important: A total of 247 drives can be supported on the RTU Master network when
RS-485 repeaters are installed.
Important: All MD60 and MD65 drives on an RTU Master network must have an
open internal Port 1. Thus, a 22-COMM-* adapter cannot be connected to
this port via the Internal Interface ribbon cable.
When a drive faults in an RTU Master network, all other drives remain operational and
unaffected.
Establishing Communications
Establish communications between the drive connected to the 1203-USB converter
and the computer. For this procedure, please refer to the following section in Chapter
4, Configuring the Converter that corresponds to the drive software tool you are using:
• “Using V*S Utilities” on page 4-4
Configuring the Drive Parameters
When setting drive parameters for the following functions to enable operation on an
RTU Master network, use each drive’s integral OIM or use the 1203-USB converter
and V*S Utilities. When using the converter, electrically connect the converter to the
computer and the first drive, establish communication with the drive, and use a drive
software tool to set its parameters. Then electrically connect the converter to the next
drive and repeat the process until the parameters in all of the drives have been set.
Setting Comm Data Rates
For each drive to be networked (including Drive 1 connected to the 1203-USB
converter), set drive parameter Comm Data Rate (103) to “4” (19.2K).
