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 (0.55 in.) wide and 128.25 mm (5.05 in.)
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 (0.73 in.) wide and 128.25 mm (5.05 in.)
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 (1.11 in.) wide and 128.25 mm (5.05 in.)
high.
slice I/O
An I/O module design that combines a small number of channels (usually between
2 and 6) 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, diagnostic
message 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.
