TP303 Cyclical Configuration
Profibus-DP as well as Profibus-PA foresees protocol mechanisms against communication failures
and errors and, as an example, during the initialization, several errors sources are verified.
After the power up the field equipments (slaves), they are ready for the cyclical data exchange with
the class1 master, but, for that, the master parameterization for the correspondent slave must be
correct. This information is obtained through the GSD files, which should be one for each device.
Through the commands below, the master executes every initialization process with Profibus-PA
devices:
§
Get_Cfg: carries the slaves’ configuration and verifies the net configuration;
§
Set_Prm: writes in the slaves' parameters and executes net parameterization services;
§
Set_Cfg: configures the slaves according to inputs and outputs;
§
Get_Cfg: a second command, where the master will verify the slaves' configuration.
All these services are based on the information obtained of GSD slaves' files.
The GSD file of
TP303
presents details of hardware revision and software, bus timing of the device
and information on cyclical data exchange.
TP303
has 2 function blocks: 1 AI and 1 Totalizer.
Besides this,
TP303
has the empty module for applications that configure only some function blocks.
The following cyclical order of blocks must be considered: AI, TOT. In case of using only the AI
block, must configure in this order: AI, EMPTY_MODULE.
Most of the Profibus configurators use two directories. These directories must have the GSD’s and
bitmap’s files of several manufacturers. The GSD and bitmap’s files for Smar devices can be
purchased via internet in www.smar.com.
See below a typical example with the necessary steps to the integration of a
TP303
device in a PA
system and that can be extended for any device:
1. Copy the GSD file of the device for the search directory of the Profibus configurator, usually
named GSD.
2. Copy the bitmap file of the device for the search directory of the Profibus configurator, usually
named BMP.
3. Once the master is chosen, the communication rate must be chosen, remembering that when
we had the couplers, we can have the following rates: 45.45 kbits/s (Siemens), 93.75 kbits/s
(P+F) and 12 Mbits/s (P+F, SK2) .If we had the link device, it can be up to 12 Mbits/s.
4. Add the
TP303
, specifying the address in the bus.
5. Choose the cyclical configuration via parameterization with the GSD file, dependent of the
application, as indicated previously.
The user can
set mode
block.
The user can monitor
the output parameter
and verify the current
state alarm.
