Preface
Definitions The Industrial Automation Glossary (publication AG-7.1) contains terms and
abbreviations that Rockwell Automation uses to describe industrial
automation systems. Table 1 lists specific terms and abbreviations that are
used in this manual.
Table 1 - Terms and Abbreviations
Term Description
AOP Add-on Profile - A Logix Designer application file that facilitates the implementation of
the 432ES. This term is also known as the module profile.
CIP Common Industrial Protocol - An industrial communication protocol that Logix 5000-
based automation systems use on Ethernet, ControlNet®, and DeviceNet®
communication networks.
CIP Safety Safety certified version of CIP™.
Client The client is a GuardLink-enabled device that connects into one of the GuardLink
circuit channels of the 432ES-IG3 network interface module. Each client is known as a
node.
DHCP Dynamic Host Configuration Protocol - A network management protocol that Internet
Protocol networks use to dynamically assign an IP address and other network
configuration parameters to each device on a network.
FW Firmware revision level.
GuardLink circuit Includes all hardware that connects to one channel of the 432ES. This hardware
includes the cables, taps, safety devices, and the terminator.
HI The on-state of the output of a logic block, or the state of an input to a logic block, or a
voltage level that is above the turn-on threshold. HI is equivalent to a Boolean value of
1.
HMI Human Machine Interface - A Rockwell Automation® product in the PanelView™ family.
Host The host is the 432ES-IG3 network interface module.
HW Hardware revision level.
LO Logic off-state or a voltage level below the turn-off threshold. LO is equivalent to a
Boolean value of 0.
MAC ID Media Access Control Identification Number - An Ethernet device on a network is
assigned a unique physical (hardware) number. This number must associate with the
IP address that is assigned to the device for proper communication.
NC No connection.
Node A GuardLink-enabled device that is installed in a GuardLink circuit. Up to 32 nodes can
connect to a circuit. The nodes are numbered from 0 to 31.
Operational state All nodes on the GuardLink channel are safety valid, and the safety Status tag for the
channel is set to a value of 1.
OSSD
Output Signal Switching Device - Typically, OSSD is a pair of solid-state signals that are
connected to a DC source supply. The signals are tested for short circuits to the DC
power supply, to the DC common, and between the two signals.
The 432ES-IG3 network interface module does not have OSSD outputs because the
safety status is transmitted over the Ethernet network. In the controller input tags, the
SIL 3 rated signal for the safety output on each channel is called Status.
PFHd The probability of failure to danger per hour.
PLC (PAC) A programmable logic controller or a programmable automation controller.
Reaction time The input reaction time is the time from when the signal changes on an input terminal
to when safety data is sent to the GuardLogix® controller.
Response time Describes the time between the initial demand that is placed on a safety device/
system, to the time when its output changes to a safe state.
Safe state One or more nodes on the GuardLink channel are not safety valid, and the safety Status
tag for the channel is set to a value of 0.
Safety valid The safety circuit receives input signals that satisfy its requirements to allow
transition to an operational state.
Tap
A tap connects a safety device to the GuardLink circuit. GuardLink-enabled taps are
nodes on the GuardLink circuit. Passive taps are not GuardLink-enabled and therefore
must connect to a GuardLink-enabled device to be considered as a node on the
GuardLink circuit. A tap is not considered as a node when the tap is a passive or
passive power tap with a shorting plug.
