Segment Info B (Byte 4 - High)
A/R
(Floating point
number)
The meaning of the data contained in
Segment Info B depends on the type of
segment it relates to. See below.
Segment Info B (Byte 3)
Segment Info B (Byte 2)
Segment Info B (Byte 1 - Low)
Auto Hold Type Loop 1 High Byte A/R A/R 0 = Auto-Hold Off, 1 = Hold above SP, 2 =
Hold below SP,
3 = Hold above and below SP
Auto Hold Type Loop 1 Low Byte
A/R A/R
Auto Hold Value Loop 1 (Byte 4 -
High)
A/R
(Floating point
number)
The distance loop 1 can be way from
setpoint before Auto-Hold activates.
Auto Hold Value Loop 1 (Byte 3)
Auto Hold Value Loop 1 (Byte 2)
Auto Hold Value Loop 1 (Byte 1 -
Low)
Events High Byte
0 0
The status of the five events are defined by
the lowest 5 bits of the low byte. A bit value
of 1 signifies the event is on.
Bit 0 = event 1, bit 1 = event 2, bit 2 =
event 3 bit 3 = event 4 and bit 4 = event 5.
Events Low Byte
A/R A/R
Segment Info B Loop 2 (Byte 4 -
High)
A/R
(Floating point

The meaning of the data contained in
Segment Info B depends on the type of
segment it relates to. See below.
(write 0 for single loop profiles)
Segment Info B Loop 2 (Byte 3)
Segment Info B Loop 2 (Byte 2)
Segment Info B Loop 2 (Byte 1 -
Low)
Auto Hold Type Loop 2 High Byte
A/R A/R 0 = Auto-Hold Off, 1 = Hold above SP, 2 =
Hold below SP,3 - Hold above and below
SP (write 0 for single loop profiles).
Auto Hold Type Loop 2 Low Byte
A/R A/R
Auto Hold Value Loop 2 (Byte 4 -
High)
A/R
(Floating point
number)
The distance loop 2 can be way from
setpoint before Auto-Hold activates.
(write 0 for single loop profiles).

Segment Data
The Segment Data is included in the command message when creating, editing or inserting
segments (see above). It is provided in two parts (Segment Info A and B).
The meaning of the data contained in Segment Info A and B depends on the type of segment
it relates to. Null is shown for unused data, these data values should be set to zero when
writing the segment data.
