Program generator

This dialog is available when the "Program generator" option or the "Program generator with
process steps" option (additionally available as of system version 02) has been activated in the
setup program (Project: Hardware arrangement > Globals).
 Manual for setup program B 705000.6, "Project configuration" section
To access this function in the central processing unit, it must be enabled with the setup program
(CPU: Online parameters > Enabling of extra codes).
 Operating manual for central processing unit B 705001.0, "Online parameters" section
You can use nine independent program generators (program generator 1 to 9) to enable nine
independent programs to run asynchronously at the same time. In total, up to 100 programs
can be managed in a program pool.
Program generator use
The program generator (extra code 225) is specially designed for heat treatment or thermal
processes and allows the definition of setpoint value profiles. A setpoint value profile forms a
program, together with the states of the operating contacts.
The program generator with process steps (extra code 228, as of system version 02) is re-
quired for ripening, cooking, and smoking plants or for heating, cooling, climatic, and test cab-
inets. In this branches, process steps are defined by the plant manufacturer as a PLC
application, for example. The user has no access to this, since specific knowledge about the
functioning of the plant is required. While creating the program, the user completes the process
steps to program sections – taking into account the presetting defined by the plant manufac-
turer.
In the program generator with process steps the switchover from one program section to the
next depends on section time or on setpoint 2 (core setpoint value, compared to actual value).
Either the section time or setpoint 2 can be entered in the program schema. As of system ver-
sion 03, the behavior is configurable.
Create programs
The program editor, which is a component of the setup program and the multifunction panel, is
used to create programs. Each program can consist of a maximum of three program channels
with up to four setpoint values (e.g. for setpoint changeover) and up to 16 operating contacts.
Up to 100 program sections are possible. Tolerance band monitoring can be set up for the first
setpoint value of each program channel.

Example of assignment of setpoint values to a controller channel of a multichannel controller mod-
ule
1) In the configuration menu for the setpoint values of the multichannel controller module, the
appropriate external signals (analog selector, e.g. NV_SP01Ext to NV_SP04Ext) are as-
signed to setpoint values 1 to 4.
2) In the NV connecting list, these external signals (here: NV_SP01Ext to NV_SP04Ext) are
connected to the corresponding signals of a central processing unit program generator (e.g.
Channel 1 SP1 to Channel 1 SP4).
