Guidelines For Configuring Turck Excon Dsb For Reading Hart Data - Honeywell Experion PKS User Manual

7 DEVICE SUPPORT BLOCK (DSB)
• If you have selected the DM80Ex digital module, in the Channel Number column, you must enter the
channel number. You must enter the channel number from 0 through 7. For other modules, the channel
number is automatically updated.
• In the Input Signal Type column, you must select the signal type supported for the AI module . This
parameter is available for configuration only when you select the PDC type as AI.
– When you select the signal type as Not Configured, this turns off the specified channel. The inputs on
this channel are not processed. You must select this value for all unused channels.
– When you select any signal type other than Not Configured, the values of the CHHIGHRANGE and
CHLOWRANGE parameters are updated based on their channel high and low values.
• In the Output Signal Type column, you must select the signal type supported for the AO module . This
parameter is available for configuration only when you select the PDC type as AO.
– When you select the signal type as Not Configured, this turns off the specified channel. The inputs on
this channel are not processed. You must select this value for all unused channels.
– When you select any signal type other than Not Configured, the values of the CHHIGHRANGE and
CHLOWRANGE parameters are updated based on their channel high and low values.
• With R410, you can modify the values of the following parameters even after a PDC is associated and
connected to a PIOMB. However, you must ensure that you reload both the DSB and the PIOMB after
modifying the parameter value. If you do not reload both the DSB and the PIOMB, there may be a break in
the connection between the DSB and the PIOMB.
– Number of Channels (NUMCHANNEL) - You can increase or decrease the Number of Channels
parameter value. There is no restriction on increasing the number of channels. However, if you want to
decrease the number of channels, you can decrease the number only until the last assigned channel
number. For example, consider a scenario where you have entered the number of channels of a PDC as
10. However, you have assigned only 6 channels (channel 0 through channel 5) to the PROFIBUS
channels. In this scenario, you can reduce the Number of Channels value to 6. If you try to reduce the
Number of Channels value to 5 or less an error message appears.

– Channel Low Range (CHLOWRANGE)
– Channel High Range (CHHIGHRANGE)

7.16.8 Guidelines for configuring Turck Excon DSB for reading HART data

• To configure the Turck Excom DSB to read HART data in addition to process data, you must configure the
PDCs based on the IO module.
– If you are using an output module, you must configure two PDCs; one for the process data and one for
the HART data.
– If you are using an input module, you must configure only one PDC.
• To read the process data, you must select the appropriate PDC type (AIH40Ex/AIH41Ex/ AOH40Ex) and
associate the corresponding net tag name.
• To read HART data, you must select the HARTInputData PDC and associate the corresponding net tag
name. When you select the HARTInputData PDC type, you must enter the number of channels in the
Number of Channels column as 1, 4, or 8 as the modules can be configured for reading 1, 4, or 8 HART
data.
• When you enter the number of channels for reading HART data, the lower grid becomes editable. You must
enter the physical channel number from where the HART data needs to be read. The physical channel
numbers start from 0.
