Functions
Libraries
IEC library
The IEC library contains the EFBs dened in IEC 61131-3 (calculations, counters,
timers, etc).
Extended library
The extended library contains useful supplements to various libraries. It provides
EFBs for mean value creation, maximum value selection, negation, triggering,
converting, building a traverse with interpolation of the rst order, edge detection and
determination of the neutral range for process variables.
System library
The system library contains EFBs in support of system functions. It provides EFBs
for cycle time detection, utilization of various system clocks, control of SFC sections
and system status display.
CLC and CLC_PRO library
The Continuous Control library can be used to set up process-specic control
loops. In particular, it offers controller, derivative and integral control functions.
The CLC_PRO library contains the same EFBs as the CLC library along with data
structures.
Communication library
The communication libraries of built-in function blocks provide easy integration of
programs that allow communication between PLCs or HMI devices from within the
PLC’s application program. Like other function blocks, these EFBs can be used in
any language to share data, or provide data to the HMI device for display to the
operator.
Diagnostics library
The diagnostics library is used for troubleshooting the control program. It contains
EFBs for action, reaction,interlocking, and process prerequisite diagnostics, along
with signal monitoring.
LIB984 library
The LIB984 library provides common function blocks used in both the 984 ladder
logic editor and the IEC languages. This allows for easy transition of portions of
application code from the LL984 environment to the IEC environment.
Fuzzy logic library
The fuzzy library contains EFBs for fuzzy logic.
Analog I/O library
The ANA_IO library is used to process analog values.
