snubber

A circuit generally used to suppress inductive loads—it consists of a resistor in

series with a capacitor (in the case of an RC snubber) and/or a metal-oxide varistor

placed across the AC load.

source load

A load with a current directed into its input; must be driven by a current source.

standard I/O

Any of a subset of Advantys STB input/output modules designed at a moderate cost

to operate with user-configurable parameters. A standard I/O module may be

reconfigured with the Advantys Configuration Software and, in most cases, may be

used in reflex actions.

standard network interface

An Advantys STB network interface module designed at moderate cost to support

the configuration capabilities, multi-segment design and throughput capacity

suitable for most standard applications on the Island bus. An Island run by a

standard NIM can support up to 32 addressable Advantys STB and/or preferred I/O

modules, up to 12 of which may be standard CANopen devices.

standard power distribution module

An Advantys STB module that distributes sensor power to the input modules and

actuator power to the output modules over two separate power buses on the Island.

The bus provides a maximum of 4 A to the input modules and 8 A to the output

modules. A standard PDM requires a 5 A fuse to protect the input modules and an

8 A fuse to protect the outputs.

STD_P

standard profile. On a Fipio network, a standard profile is a fixed set of configuration

and operating parameters for an agent device, based on the number of modules that

the device contains and the device’s total data length. There are 3 types of standard

profiles: Fipio reduced device profile (FRD_P), Fipio standard device profile

(FSD_P), and the Fipio extended device profile (FED_P).

stepper motor

A specialized DC motor that allows discrete positioning without feedback.
