b. else, variable is moved to the I/O area
Then, with the remaining variables in the shared area:
2. Variables mapped by fieldbus:
a. Variable is moved to the fieldbus area
Drivers for the I/O area and the fieldbus areas are added automatically if not already present in the PLC
program (the drivers are located in the “I/O Configuration” under “Physical Hardware” in the PLC)
Note 1: It is no longer possible to map an input to both I/O and Fieldbus at the same time. A signal
mapped to both I/O and Fieldbus will only be mapped to I/O after the conversion.
Note 2: It is only possible to map an output to both I/O and Fieldbus at the same time if the name starts
with SO_. A signal mapped to both I/O and Fieldbus with another name will be moved to the I/O area and
is thus no longer possible to map to the Fieldbus.
Note 3: It is no longer possible to remap the individual elements of an array to the Fieldbus, only the
whole array can be remapped. If an array is used and some elements have been remapped the whole
array will be moved to the Shared_Variables group and removed from the Fieldbus mapping. This means
none of the signals in the array will be available after the conversion. If wanted the whole array can be
moved back to the fieldbus, but it will NOT be possible to remap the individual elements to get back to the
old mapping used before the conversion.
4.2.1.2 Compatibility between PM4000 Tightening and Gauging
PM4000 Gauging can read a Tightening setup from file and convert it to a Gauging setup but not vice
versa. A setup converted to a Gauging setup is no longer possible to open with PM4000 Tightening.
4.2.1.3 Upgrade of PLC environment
The PLC part of a setup is handled by a separate program called Multiprog. This program is upgraded
much more seldom than the rest of PM4000 and it is also backwards compatible. A newer Multiprog can
read an older PLC program and convert it to the new version. An older Multiprog cannot read a PLC
program created by a newer Multiprog.
Two versions of Multiprog are currently included in the installation kit for PM4000. For Windows XP it is
recommended to use Multiprog 4.6. For Windows Vista or later Multiprog 5.3 must be used. To open a
setup that have a PLC program of version 5.3 Multiprog version 5.3 must be used also when running on
Windows XP.
