Manual VIPA System 200V Chapter 5 238-2BC00 - Combination module
HB97E - SM-AIO - Rev. 12/32 5-17
Digital part - Counter - Fast introduction
The combination module can only be used together with a CPU 21x or with
the DP-V1 Profibus coupler (253-xDP01)! The project engineering takes
place in the Siemens SIMATIC manager. For this the import of the
corresponding GSD file is required which can be found at the "service" area
under www.vipa.com.
After installation of the GSD file the combination module can be found at
the hardware catalog at:
Additional Field devices > I/O > VIPA_System_200V > ...
as 2 modules:
238-2BC00 (1/2) AI4/AO2*12Bit
238-2BC00 (2/2) Counter
Please take care that you always configure both module parts in the
sequence shown above
The combination module has 3 parameterizable integrated counter that are
controlled via the input channels. During the counter process, the counter
signal is registered and evaluated. Operating mode and additional functions
are set via the parameterization.
By placing both module parts within hardware configuration the counter
parameters can be set with the "238-2BC00 (2/2) Counter" properties.
The digital part has to be provided with 60Byte parameter data. Here you
define among others:
• Alarm behavior
• Assignment I/O
• Counter operating mode res. behavior
• Start value for load value, end value and comparison value register
You may alter the parameters during runtime by using the SFC 55, 56, 57
and 58, except of the parameters in record set 0. Here you have to send
the wanted parameters to the counter by means of the user application
using the according SFC and sending the data as record set.
The controlling of the counters happens by the output image. Here the
respective counter can be controlled by commands and the software gate
can be (re-)set.
After transmitting a command, the respective counter confirms the
successful processing of the command by setting the corresponding
handshake bit. To enable the respective counter to accept a new
command, you have to transmit the command 00h to the counter. After
writing the command 00h, the handshake bit assigned to this counter will
be reset. The counter is released for a new command.
