Glossary

sink load	An output that, when turned on, receives DC current from its load.
size 1 base	A mounting device, designed to seat an STB module, hang it on a DIN rail, and
	connect it to the island bus. It is 13.9 mm wide and 128.25 mm high.
size 2 base	A mounting device, designed to seat an STB module, hang it on a DIN rail, and
	connect it to the island bus. It is 18.4 mm wide and 128.25 mm high.
size 3 base	A mounting device, designed to seat an STB module, hang it on a DIN rail, and
	connect it to the island bus. It is 28.1 mm wide and 128.25 mm high.
slice I/O	An I/O module design that combines a small number of channels (usually between
	two and six) in a small package. The idea is to allow a system developer to purchase
	just the right amount of I/O and to be able to distribute it around the machine in an
	efficient, mechatronics way.
SM_MPS	state management_message periodic services. The applications and network
	management services used for process control, data exchange, error reporting, and
	device status notification on a Fipio network.
SNMP	simple network management protocol. The UDP/IP standard protocol used to
	manage nodes on an IP network.
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	An Advantys STB network interface module designed at moderate cost to support
network	the configuration capabilities, multi-segment design and throughput capacity
interface	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 six of which may be standard CANopen devices.
standard power	An Advantys STB module that distributes sensor power to the input modules and
distribution	actuator power to the output modules over two separate power buses on the island.
module	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.
