The Block Type ID Parameter contains an ID which describes the block type. The
block type ID of the "CDG Transducer Block" is set to "14". The other defined block
types are listed in Appendix B.
This bit mapped byte parameter provides the following additional information of the
PCG55x sensor (CDG):
Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0
Res. Res. Res. Res. Res. Underrange
Exceeded
Overrange
Exceeded
Reading
Invalid
Res. = Reserved
• Underrange
Exceeded
This bit is set ("1") if the ProcessValue PV is below the parameter Underrange
(ID 45) of the CDG sensor instance (
→ 36].
• Overrange Exceeded
This bit is set ("1") if the ProcessValue PV is above the parameter Overrange
(ID 44) of the CDG sensor instance (
→ 36).
• Reading invalid
This bit represents the logical inversion of the parameter "Reading Valid"
(ID 23) of the CDG sensor instance (
→ 36).
This parameter contains the following information:
Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0
Byte 0 0 0 0 0 0 0 0 SF
Byte 1 0 0 0 0 0 0 EF 0
• SF = Sensor Element Failure
• EF = Electronics Failure
This byte is always "0". (The CDG Sensor does not produce any warnings)
