Configuration
3.15
In order to enter the local adjustment mode, place the magnetic tool in orifice
“Z”
until flag
“MD”
lights up in the display. Remove the magnetic tool from
“Z”
and place it in orifice “S” until the
message
“LOC ADJ”
is displayed. The message will be displayed during approximately 5 seconds
after the user removes the magnetic tool from
“S”
. By placing the magnetic tool the user will be able
to access the local adjustment tree in the monitoring mode.
Browse to parameter P_VAL (PRIMARY_VALUE).
Supply 4.0mA or the lower value to the terminal block and wait until the read of the parameter
stabilizes in the display.
Browse to parameter “LOWER”. After that, in order to start calibration, the user will act on the
parameter “LOWER” by placing the magnetic tool in “S” down to 4.0 mA.
Let’s take the upper value:
Supply 20.0mA or the upper value to the terminal block and wait until the readout of parameter
P_VAL stabilizes, and then actuate parameter UPPER up to 20.0.
Trim mode exits via local adjustment automatically when the magnetic tool is not used during
approximately 16 seconds.
NOTE
Keep in mind that even when parameters LOWER or UPPER present the desired value, they must be
actuated so that calibration is performed.
Limit Conditions for Calibration:
For every writing operation in the transducer blocks there is a code indication for the operation
associated with the writing method. These codes appear in parameter XD_ERROR every time a
calibration is performed. Code 16, for example, indicates a successfully performed operation.
Lower:
0.0mA < NEW_ LOWER < 9.0mA
Otherwise, XD_ERROR = 22
Upper:
15.0 mA < NEW_UPPER < 22.0mA
Otherwise, XD_ERROR = 22.
NOTE
Codes for XD_ERROR:
16:
Default Value Set
22:
Out of range
26:
Invalid Calibration request
27:
Excessive Correction
Transducer Display – Configuration
Using the
Simatic PDM or any other configuration tool
is possible to configure the Display
Transducer block. As the name described it is a transducer due the interfacing of its block with the
LCD hardware.
The Transducer Display is treated as a normal block by
any configuration tool
. It means, this block
has some parameters and those ones can be configured according to customer's needs.
The customer can choose up to six parameters to be shown at LCD display, they can be parameters
just for monitoring purpose or for acting locally in the field devices by using a magnetic tool. The
seventh parameter is used to access the physical device address. The user can change this
address according to his application. To access and configure the Display Block, please, go to the
main menu, select "Device OnLine Configuration - Display Block":
