MFL: Modular PCS 7 block library
for technological functions
■ Overview
"MFL" is a modular function block library for the SIMATIC PCS 7
process control system V5.2, V6.0 and V6.1. This library enables
the maximum performance to be obtained from SIMATIC PCS 7
and allows flexible response to specific technological demands.
The blocks offered for technological functions such as motor,
valve, controller etc. are implemented with small, fast basic
blocks. These are delivered together with the CFC sources and
can therefore be adapted flexibly if there are special requirements.
All blocks of a process tag can be visualized and operated
by means of a variable faceplate. Operator panels can also
be integrated into the SIMATIC PCS 7 system configuration by
means of the MFL for on-site operation.
■ Application
The PCS 7 library "MFL" includes function blocks for:
• Motor, 1 direction of rotation
• Motor, 2 directions of rotation
• Motor, 2 speeds
• Motor FU
• Valves
• Motor slide
• Controller
• Proportioning
• Interlocking block
• Analog value monitoring.

■ Function
Modular blocks
In contrast to other libraries, blocks for the implementation of
technological functions such as motor, valve, controller etc. are
created in MFL from small, fast basic blocks that are graphically
interconnected in the CFC and subsequently translated as a
block type.
Since the graphical sources are also supplied, the user can, if
required, very easily adapt the blocks to specific industries or
plants without having to develop new basic functions, e.g. fault
philosophy, special control logic or colors.
Adaptable faceplates
For special applications, blocks can be used several times or
different blocks can be combined with one another (4-way
valves, motors with special on-site switches etc.) and the faceplates
can be correspondingly adapted. The number and functions
of the required keys, symbols, and status displays can be
programmed in interactive mode.
Process tag-oriented faceplates
In contrast to other libraries, in which each block has its own
faceplate, the faceplate for the MFL is not rigidly linked with a
structure variable, but adapts itself dynamically to the called
CFC-Typical. All operable blocks belonging to a process tag can
thus be visualized and operated by means of a shared faceplate
(see graphic with one motor block, two interlock blocks, current
indicator and operating hours counter).
Multiple views
Blocks may occur several times within one process tag, e.g. several
locking function blocks for one motor. The faceplate then
adapts itself automatically to the conditions, and enables the operator
to choose the required block by means of a popup menu
(release, automatic etc.). Similarly, the view of a block is not displayed
if it is not a component of the process tag.
