Glossary-3
OIM (Operator Interface Module)
A device that can be used to configure and control a DPI drive or a MDI drive. DPI
OIMs (20-OIM-xxx) and MDI OIMs (22-OIM-xxx) can be used to configure connected
peripherals.
N NVS (Non-Volatile Storage)
NVS is the permanent memory of a device. Devices such as the converter and drive
store parameters and other information in NVS so that they are not lost when the
device loses power. NVS is sometimes called “EEPROM.”
P PCCC (Programmable Controller Communications Commands)
PCCC is the protocol used by some controllers to communicate with devices on a
network. Some software products (for example, V*S Utilities) also use PCCC to
communicate.
Ping
A ping is a message that is sent by a DPI drive to its peripheral devices. They use the
ping to gather data about the product, including whether it can receive messages and
whether they can log in for control.
S Status Indicators
Status indicators are LEDs that are used to report the status of the converter. There
are three status indicators on the converter.
V*S Utilities Software
V*S Utilites software is a tool for monitoring and configuring Reliance Electric products
and adapters. It can be run on computers running various Microsoft Windows
operating systems. V*S Utilities (version 4.06 or higher) can be used to configure the
1203-USB converter and connected drive.
X Xmodem
Developed by Ward Christensen in 1978, Xmodem is a protocol used to transfer data.
You can use the Xmodem protocol to flash the firmware in the converter or a device
connected to it.
Z Zero Data
When communications are disrupted (for example, a cable is disconnected), the
converter and connected drive can respond with zero data. Zero data results in the
drive receiving zero as values for command data. If the drive was running and
usingthe Reference from the converter, it will stay running but at zero Reference.
