sys
) is
Fill
or
Mdplc
.
For
src
(Source) parameters, if you select PAR 4024
Fieldbus M->S1 mon
in the corresponding enum, the value of
parameter 4020 is automatically set to the IPA of the
src
.
E.g.:
if PAR 4020
Fieldbus M->S1 ipa
= 610 then PAR 610
Ramp ref 1 src
= PAR 4020
Fieldbus M->S1 ipa
.
For
src
parameters with a FB type other than 0, the datum coming to the fieldbus is not written in the enum selection
but directly in the mon associated with the
src
.
E.g.:
PAR 4020
Fieldbus M->S1 ipa
= 610, the reference from the bus is sent to PAR 620
Ramp ref 1 mon
, it does
not modify the selection of PAR 610
Ramp ref 1 src
which continues to be set to PAR 4020
Fieldbus M->S1 ipa
.
If it contains a valid IPA and is forced to 0 the corresponding sys parameter assumes the value of Fill (16 or 32 de-
pending on the previous setting), to guarantee that the structure of the exchanged data area is not changed.
PAR 4022
Fieldbus M->S1 sys
Format of the datum to exchange
This parameter is automatically adjusted to the recommended value when the corresponding PAR 4020...4170
Field-
bus M->Sn ipa
is modified. Although the automatic value is user-definable, acceptable values depend on the datum
IPA parameter: some combinations are not allowed and generate a configuration alarm at restart.
Values:
•
Not assigned
: if set to “
Not assigned
” this and all subsequent groups (regardless of their sys) are not
part of the data exchanged, regardless of the IPA.
•
Fill16/32
: the datum is exchanged on the fieldbus but not written in any parameter.
•
Eu
: the datum is exchanged in 16-bit signed integer format with the parameter unit configured in the cor-
responding IPA or, in the case of src with the corresponding mon (e.g.: if PAR 4020
Fieldbus M->S1 ipa
= PAR 610
Ramp ref 1 src
and PAR 4022
Fieldbus M->S1 sys
= Eu the datum is in rpm), multiplied by
div. This setting is only possible for some parameters. See the table of FBUS types in the list of param-
eters. For these parameters the datum is exchanged every ms.
•
Eu_float
: Eu_float: same as Eu, but the datum is in floating point 32-bit IEEE754 single precision for-
mat.
•
Count16/32
: the datum is exchanged in internal units (see scaling table) every ms (e.g.: if PAR 4020
Fieldbus M->S1 IPA = 610, PAR 610
Ramp ref 1 src
and PAR 4022
Fieldbus M->S1 sys
= Count16 the
datum is scaled so that a value of 0x4000 produces a reference equal to PAR 680
Full scale speed
).
This setting is only possible for some parameters. See the table of FBUS types in the list of parameters:
if the field is empty Count cannot be set in the parameter. Some parameters permit the use of Count16
(usually values in which there is no need to exchange the least significant 16 bits) and Count32, accord-
ing to the following rule: if FBUS = 32bit only Count32 can be set, if 16hi or 16lo Count32 and Count16
can both be set, indicating which word of the parameter is actually used. If Count32 is used and the
internal type of the parameter is FLOAT the datum must be exchanged in floating point IEEE754 single
precision format, otherwise as an integer (signed or unsigned, again according to the internal type).
•
MdPlc16/32
: this indicates that the datum is for use by the MdPlc application, which will use the value
of PAR 4024...4174
Fieldbus M->Sn mon
accordingly. If set to MdPlc16 the 16 bits of the low part of
the mon are exchanged, if set to MdPlc32 all 32 bits are exchanged. All this applies if PAR 4020...4170
Fieldbus M->Sn mon
= 0, otherwise it behaves in the same way as Count.
•
Par16/32
: this is the default setting for all parameters with FB type empty so that data cannot be ex-
changed at 1 ms and the datum is updated in background. The datum format depends on the format of
the parameter and the setting: with Par16 the datum is a 16-bit integer (signed or unsigned, according to
the external type of the parameter) with the same unit of measure as the selected parameter (multiplied
by div); Par16 is only available if the parameter is not actually a 32-bit one (e.g. it is not possible for iPad
and Compare). With Par32 the format is float if the external type of the parameter is float, otherwise it
is integer, always with the unit of the parameter. Parameters with FB type not empty can also be ex-
changed as PAR, according to the same rules listed above.
If using the CANopen fieldbus, the sys is also used to structure the data area in 8-byte PDOs. The PDOs are created
starting from the first group and it is necessary to guarantee that the data are contained in the PDO. Therefore, for ex-
ample, a setting with PAR 4022 Fieldbus M->S1 sys = Count32, PAR 4032 Fieldbus M->S2 sys = Count16, PAR 4042
Sys M->S3 Fieldbus = Count32 is not valid, as the datum in group 3 would straddle the first two 2 PDOs. In these
cases, shorter PDOs can be generated by using the Count setting with IPA 0 (in the example PAR 4040
IPA M->S3
Fieldbus
= 0, PAR 4042
Fieldbus M->S3 sys
= Count16, PAR 4050
Fieldbus M->S4 ipa
= IPA of the parameter that
was previously in 3 and PAR 4052
Fieldbus M->S4 sys
= Count32, thus using a first PDO with 6 bytes), or by creating
