Mnemonic Name Purpose
CBCM Clutch Brake Continuous Mode Used for press applications where continuous operation is desired.
CBIM Clutch Brake Inch Mode Used for press applications where minor slide adjustments are required, such as press setup.
CBSSM Clutch Brake Single Stoke Mode Used in single-cycle press applications.
CPM Crankshaft Position Monitor Used to determine the slide position of the press.
CSM Camshaft Monitor Monitors motion for the start, stop, and run operations of a camshaft.
EPMS Eight-position Mode Selector Monitors eight safety inputs to control one of the eight outputs that correspond to the active input.
AVC Auxiliary Valve Control Controls an auxiliary valve that is used with a main valve.
MVC Main Valve Control Controls and monitors a main valve.
MMVC Maintenance Manual Valve Control Used to drive a valve manually during maintenance operations.

Mnemonic Name Purpose
ENPEN Enable Pendant Monitors two safety inputs to control one output and has a 3-s inputs-inconsistent timeout value.
ESTOP E-stop Monitors two safety inputs to control one output and has a 500-ms inputs-inconsistent timeout value.
RIN Redundant Input Monitors two safety inputs to control one output and has a 500-ms inputs-inconsistent timeout value.
ROUT Redundant Output Monitors the state of one input to control and monitor two outputs.
DIN Diverse Input Monitors two diverse safety inputs to control one output and has a 500-ms inputs-inconsistent timeout value.
FPMS 5-position Mode Selector Monitors five safety inputs to control one of the five outputs that corresponds to the active input.
THRS Two-handed Run Station Monitors two diverse safety inputs, one from a right-hand push button and one from a left-hand push button, to
control one output.
LC Light Curtain Monitors two safety inputs from a light curtain to control one output.

Type Mnemonic Name Purpose
Array (File)
COP
(1)
Copy Copy binary data from one tag to another (no type conversion).
FAL
(2)
File Arithmetic and Logic Perform copy, arithmetic, logic, and function operations on data that is stored in an array.
FLL File Fill Fill the elements of an array with the Source Value, while leaving the source value unchanged.
FSC File Search and Compare Compare the values in an array, element by element.
SIZE Size In Elements Find the size of a dimension of an array.
Bit
XIC Examine If Closed Examines the data bit to set or clear the rung condition.
XIO Examine If Open Examines the data bit to set or clear the rung condition.
OTE Output Energize Controls a bit (it performs both Set and Clear operations based on rung state).
OTL Output Latch Set a bit (retentive).
OTU Output Unlatch Clear bit (retentive).
ONS One Shot Allows an event to occur one time.
OSR One Shot Rising Sets an output bit for one scan on the false-to-true (rising) edge of rung state.
OSF One Shot Falling Sets an output bit for one scan on the true-to-false (falling) edge of rung state.
