NOTE
Only 1-5V sensor type will be supported when HART is enabled.
10.11.11 Comparing parameters between Series C and PMIO
HPVCHAR, which is used in PM I/O, is not used Series C I/O. PVCHAR are used instead, and only
valid enumerations (depending on the settings for HENABLE and IOM TYPE) are displayed to you.
Some HART parameters are only valid for HART Protocol Version 6. Series C IOMs support HART
6.0 and later version device features such as Extended Device Status, Configuration Change
Counter, Variable Status and Classification Codes. The current release of Series C I/O supports
these HART 6.0 and later version device parameters:
Parameter Tab Description
HMAXDEVVARS Indicates the last device variable code supported by the device.
Information can be used by the host applications.
HNCFGCHG Configuration change counter is a counter maintained by HART 6.0
and later version device which is incremented every time configuration
is changed. This is improvement over the single 'configuration
changed bit' in previous HART releases
HNSMMINPRE Minimum number of preamble bytes to be sent with the response from
device to the IOM. Series C IOMs take advantage of this configuration if
supported by the device to minimize the bytes sent from device in
response messages.
HDYNCC Variables Dynamic / device variable classification code
HDYNST Variables Dynamic / device variable classification code
HSLOTCC Variables Dynamic / device variable classification code
HSLOTST Variables Dynamic / device variable classification code
10.11.12 Parameter values not copied during Block Copy
IOP and CHANNUM are the only configuration parameter values not copied during a Block Copy
operation.
10.12 Defining AI Channel Blocks
The AI channel block represents a single analog input point on either an AI-HART or AI-LLMUX or
AI-LLAI I/O Module. The type of analog input IOM needed is based on the:
l type of field sensor that is providing the input to the channel
l PV characterization options you select (as listed in the table in Determining PV
Characterization)
