How to select and configure the processor
At a Glance Software installation generic to the applications is described in the manual Common functions . However the specifics, such as the selection of the processor and its configuration, are described here.
Note: using process control in an application imposes a MAST task of the periodic type.

How to access process control application parametering
At a Glance The method of software installation for process control channels is the same as that used for PL7 application specific functions. l l
An application specific function has: l l l dedicated screens, specific instructions, language objects (See
Process control language objects, p. 283).
Installation of a process control starts with accessing the parametering screens, consisting of: configuration screens (in offline and online mode), debug screens (in online mode).

Runtime screens adjustment tools
At a Glance The runtime screens editor allows the use of bar charts and specific library objects for the operation of control loops. Animation is automatic and is a simple process.
To find out which objects are available and how to use them, please refer to the
Runtime screens editor user manual.

Operating control loops with XBT terminals
At a Glance
Control page
Some Magelis XBT-F terminals are able to manage control loops.
Note: when these tools are used, to make the XBT/PLC dialog transparent, exchanges are made by default in the word zones %MW3228 to %MW3242 and
%MW3350 to %MW4090 (See
Using the Man-Machine Interface, p. 180).
l l l l l
In addition to the services offered by the XBT-L1000 software and the Magelis terminals, the XBT-F terminal offers specialized pages to manage each control loop: control page, operating page, adjustment page, monitoring page, alarm page.
Control pages are used to control each control loop, manual mode, automatic mode, autotuning, etc.

Autotuning the control loops
At a Glance Autotuning is applied to most of the processes, such as temperature regulation, flow regulation, pressure regulation, etc.
The loop controllers built into these control loops are used to calculate a set of adjustment parameters (Kp, Ti, Td) on autotune request.
l l l
These parameters can be accessed via:
PL7 debug screens, an animation table, an adjustment screen specific to an XBT-F terminal.
XBT-F autotuning page
This page is used to autotune a control loop.

Setpoint programmer
At a Glance All process control channels can be configured using the setpoint programmer.
l l l
The features of a setpoint programmer are as follows:
1 to 6 profiles, a maximum of 48 segments distributed over the configured profiles,
Profiles can be assigned to several control loops.
Note: when the setpoint programmer is interfaced to a single loop, the PV measurement tracking function can be used.
Note: the XBT-F terminal offers an adjustment page and an operating page specifically for the setpoint programmer. These pages are used to modify the desired setpoint profiles.
Configuration screen for a setpoint programmer
Profiles are assigned to a control loop via a configuration screen.
