GSD
Generic Station Description: A GSD contains an XML-based description of the properties of
IO devices such as communications parameters as well as number, type, configuration data,
parameter and diagnostics information of modules. The use of GSD files makes it easier to
configure the master and DP slave.
IP20
Degree of protection to IEC 60529: Protection to prevent finger contact and ingress of
particles larger than 12 mm Ø.
IP65
Degree of protection to IEC 60529: Complete protection against touch, protection against the
ingress of dust and protection against jet water from all directions.
IP66
Degree of protection to IEC 60529: Complete protection against touch, protection against
ingress of dust and protection against damaging penetration of heavy seas or strong jet
water.
IP67
Degree of protection to IEC 60529: Complete protection against touch, protection against
ingress of dust and protection against damaging penetration of water at a certain pressure
during immersion.
ITP
Industrial Twisted Pair; bus system suitable for industrial used based on the twisted pair
standards IEEE 802.3i: 10BASE-T and IEEE 802.3j: 100BASE-T.
Lightning arrester
These are capable of diverting multiple lightning currents or parts of them without any
damage occurring.
Loop resistance
Total resistance of the outward and return line of a cable.
Master
A master station that is in possession of the token can send data to other nodes and request
data from these (= active node.)
