FI303 - Operation and Maintenance Instruction Manual

•
After choosing the master, define the communication rate. Don´t forget that the couplers may
have the following communication rates: 45.45 kbits/s (Siemens), 93.75 kbits/s (P+F) and
12Mbits/s (P+F, SK2). The IM157 link device may have up to 12Mbits/s;
•
Add the FI303 and specify its bus address;
•
Choose the configuration via parameterization with the gsd file, according to the application, as
seen previously. Notice that this choice must match the AO blocks operating mode. Under these
conditions mind the status value of the setpoint value, which should be 0x80 (Good) when in
Auto mode, and 0xc4(IA) when in Rcas. Three AO blocks may be operated in the following cyclic
order: AO_1, AO_2 e AO_3. If only 2 AOs are to be applied, there should be: configuration for
the AO_1, configuration for the AO_2 and EMPTY MODULE.
The watchdog condition may be activated, prompting the equipment to enter a fail-safe mode when
detecting a communication loss between the slave and the master equipment. Since the FI303 will
be on a final element, it is recommended that a fail-safe value be configured.
The
Simatic PDM (Process Device Manager) configuration software from Siemens, for example,
can configure many parameters of the Input Transducer block.
Figure 3.2 - Function and Transducer Blocks
To make the configuration of Transducer Block, we need to select the menu "Device"
Use this menu:
- To change the device address;
- To make the up/download of parameters;
- To configure the Transducer Block, Analog Output Block and Display Block;
- To calibrate the converter;
- To make the reset by software, to protect the device against writing and to
simulate the value from transducer block to analog output block;
- To save and restore data calibration.
To make the configuration of Transducer Block, we need to select the menu "Device- OffLine
Configuration-Transducer. We have 3 Transducer Blocks:
The device was
created as
FI303.
Here, you can
see all blocks
instantiated.
As you can see
the Transducer
and Display are
treated as special
type of Function
Blocks, called
Transducer
Blocks.
