CMD software - (IBS CMD G4) A software package that enables
configuration, monitoring, and diagnostics of all connected devices
in an Interbus network.
communications module - Devices such as drives, controllers,
and computers usually require a module to provide a
communication interface between them and a network such as
Interbus. A module reads data on the network and transmits it to the
connected device. It also reads data in the device and transmits it to
the network.
The RECOMM-IBUS module is an module that connects SP600
drives to a Interbus network. Modules are sometimes also called
“adapters,” “cards,” “embedded communication options,” “gateways,”
and “peripherals.”
Communication Reference (CR) - Identifies an Interbus device in
the parameter data channel (PCP). To send a PCP service to a
device, its CR must be specified. The CRs begin at “2” and must be
assigned in ascending order.
controller - Also called programmable logic controller. A solid-state
control system that has a user-programmable memory for storage
of instructions to implement specific functions such as I/O control,
logic, timing, counting, report generation, communication,
arithmetic, and data file manipulation. A controller consists of a
central processor, input/output interface, and memory.

scanner.
data rate - The data rate is the speed at which data is transferred
on the Interbus network (fixed at 500 K).
Datalink - A type of pointer used by some SP600 drives to transfer
data to and from the controller. Datalinks allow specified parameter
value(s) to be accessed or changed without using explicit
messages. When enabled, each Datalink consumes either four
bytes or eight bytes in both the input and output image table of the
controller. The drive determines the size of Datalinks.
DPI - A peripheral communication interface used by various
Reliance Electric drives and power products.
DPI peripheral - A device that provides an interface between DPI
and a network or user. Peripheral devices are also referred to as
“adapters” and “modules.” The serial converter and SP600 OIM are
examples of DPI peripherals.
