Table A-29 PII for analog output module with HART (IEEE754 󹪞oating point format)
PII 7 6 5 4 3 2 1 0 Description
IB x IEEE variable 1 in 󹪞oating
point representation, as
speci󹪝ed for HART
You can select the number of
IEEE variables in the con󹪝gu‐
ration.
You can map any IEEE varia‐
ble of a 󹪝eld device into the
PII. See section "IEEE tags
(Page 396)"

HART status byte: Status codes used by the PROFIBUS PA pro󹪝le for ET 200iSP:
• 01001100 (4C
H
) uncertain, initial value (before 󹪝rst contact)
• 00011000 (18
H
) bad, no communication (communication error)
• 00001100 (0C
H
) bad, device failure (device fault)
