7.10 Turck Excom Device Support Block (Turck Excom DSB)
The Turck Excom DSB runs on the PGM and represents one Turck Excom device (field device) in the
PROFIBUS network. The Turck Excom DSB processes the raw data from the Turck Excom devices and
converts it to the PDC format supported by the Experion. The Turck Excom DSB communicates with the master
PGM for data conversion.
A single Turck Excom DSB can support 8 or 16 input/output modules depending on the size of the backplane.
Each module can be configured as digital or analog module based on the number of channels, sensor types, and
mode parameterization.
Support for processing HART data
With R410, Turck Excom DSB supports processing of HART data for the following modules.
• AIH40Ex
• AIH41Ex
• AOH40Ex
If the above I/O modules are connected to HART devices, the Turck Excom DSB processes secondary variables
(HART data).
Gateway redundancy
With R410, Turck Excom DSB provides gateway redundancy. In addition, Turck Excom DSB can be configured
to command switchover and provide status of the redundant gateway.
Turck Excom station can accommodate 2 gateway modules in the I/O rack which act as a redundant pair. At any
point of time only one gateway is active. PGM supports only line redundancy.
Guidelines for configuring DM80Ex digital module
You must configure the correct number of channels (NUMCHANNEL) parameter for the DM80Ex digital
module as this value is not automatically updated for this module. The number of channels are not updated
automatically for this module for the following reasons.
• This module can be configured either as inputs or outputs.
• This module can be configured as 8 inputs or 8 outputs.
• This module can be configured as 4 inputs and 4 outputs.
• This module can configured as 5 inputs and 3 outputs.
• Set of 2 channels can be freely configured as either inputs or outputs.
Attention
The default NUMCHANNEL value for DM80Ex is 8.
When this module is configured as input/output module, 2 PDCs must be configured and the number of
channels for each PDC must be entered manually. For example, if the module is configured for 6I/2O, then
number of channels for input PDC is 6 and 2 for output PDC.
Guidelines for configuring the DF20Ex F as a Frequency Counter module
While configuring the DF20Ex as a Frequency Counter module, you must configure one input
(FreqCounter_Input) and one output (FreqCounter_Output) PDC. The input PDC has 2 channels and the output
PDC has 2 channels. In the output PDC, the channels are configured as digital outputs.
This module provides one control byte per input to control its counting direction and bit 3 of each control byte
is reserved for this purpose. Hence the 2 channels represent the control bit information.
Channel 0 represents control bit information for the first input and channel 1 represents control bit information
for the second input. This means that the channel 0 controls the counting direction of first input and channel 1
controls the counting direction of second input.
