1 Introduction
This quick start guide describes an approach how you can configure the RESISTOMAT®2311 via TIA Portal
using the example of S7-1511 CPU. Please note that the samples here cannot be directly used in your
production line because they have beed extremely simplified to reach a better understanding. Therefore, you
may have to complete them by checking of status, error, length values etc.
Note: Please also note that you will have to use the RESISTOMAT®2311 PROFINET manual to get
futher information about input and output parameters (cyclic as well acyclic data transfer).

3 Installation of GSDML files
Note: Please make sure that your GSDML file is compatible to the field bus firmware in the Resistomat
2311. Also for compatibility reasons, uninstall all previous GSDML files of particular device if you
have any!
1. Go to Options→Manage general station description files (GSD) (a)
2. Navigate to your Resistomat 2311 GSDML directory (a) (you will find the GSD on
www.burster.com/en/download-area), select the GSDML file (b) and click Install (c)

3. Please select an ethernet port on the S7 and hold the left mouse button down to connect the S7 with
Resistomat 2311 (a):
4. Change now to Network view (a) to assign a controller to the Resistomat 2311. Click on the link “Not
assigned” (b) of Resistomat 2311 and select your controller (c):

IMPORTANT: Check if devices are also connected physically to the right ports. You find the port number
assignment in the section Port-Identification of Resistomat 2311 PROFINET manual
5. Change the device name in Device view →Properties →General →Ethernet addresses:

5 Perform a measurement and read the measurement result
In this section, you will learn how to create a simple program to start and stop a measurement periodically
and display the measured resistance value with corresponding unit in a watch table. You will need to refer to
sections PLC inputs and PLC outputs of the RESISTOMAT®2311.
PROFINET manual to understand the meaning of inputs and outputs bytes.
1. Add the variables out_start, in_ready and in_error as shown below
Note: Please note: the addresses may be different. You have to check them in the Device view 
Device overview of the Resistomat®2311:
2. Expand the tree node Program blocks in the Project tree and double click Add new block:

10 of 17
3. Select in the new window Organization block (a) →Cyclic interrupt (b). Set the cyclic time to
3.000.000 µs (c). As language set SCL (d) and click OK:
4. Type in the following source code in the code field of the new block:
IF "out_start" =TRUE THEN
"out_start" := FALSE;
IF "in_error" = FALSE THEN
"read_meas_value"();
END_IF;
ELSE
IF "in_ready" = TRUE THEN
"out_start" := TRUE;
END_IF;
END_IF;
// Is measurement start set?
// Then reset it
// No error?
// Read the measurement value
// Is 2311 ready for a new measurement?
// Start a new measurement
a
b
c
d

5. Add a new function block and name it read_meas_value:
You will use this block to read the measurement value string, containing the measurement resistance value
and the corresponding unit. For this acyclic operation, you will also need an instance of RDREC block.
Variables:

6. Type in the following source code in the new function block:
Sourcecode:
"Data_block_1".MeasValueAsString := '---';
REPEAT
"RDREC_DB"(REQ := TRUE,
ID := 296,
INDEX := 12,
MLEN := 2,
VALID => #Valid,
BUSY => #Busy,
ERROR => #Error,
STATUS => #Status,
LEN => #LenRead,
RECORD := #MeasStatus);
UNTIL NOT #Busy
END_REPEAT;
IF #Error = TRUE OR #Status <> 0 OR #MeasStatus <> 0 THEN
RETURN;
END_IF;
IF #Error = TRUE OR #Status <> 0 OR #MeasStatus <> 0 THEN
RETURN;
END_IF;
REPEAT
"RDREC_DB"(REQ := TRUE,
ID := 296,
INDEX := 15,
MLEN := 64,
VALID => #Valid,
BUSY => #Busy,
ERROR => #Error,
STATUS => #Status,
LEN => #LenRead,
RECORD := #MeasValueAsByteArray);
UNTIL NOT #Busy
END_REPEAT;
Chars_TO_Strg(Chars := #MeasValueAsByteArray,
pChars := 0,
Cnt := #BytesWritten,
Strg => "Data_block_1".MeasValueAsString);
// Init Measurement value string
// 296: HW-ID for slot 48
// Index 12: Measurement Status
// Max. lenth of data to read
// New data received and valid
// Read not completed yet
// Read error
// Read status
// Number of bytes was read from device
// Measurement status
// 296: HW-ID for slot 48
// Index 15: m
easured resistance value
// Max. lenth of data to read
// New data received and valid
// Read not completed yet
// Error
// State
// Number of bytes were read
// Array[0..63] of Byte
// Byte array
// Start position
// Number of bytes copied
// Destination string

13 of 17
Note: Your Hardware identifier for the slot 48 (Current measurement values) may be different. You can
check it in the Device view → Device Overview → System constants:
7. Add a new data block via Add new block (a) →Data block and insert the string variable
‘MeasValueAsString’ into it (b):
a
b

8. Before you load the project into the CPU you have to set the IP addresse of your CPU. To do this please
go to Device view and select Ethernet addresses (a) in General tab. Set now the IP-Address and a
subnet mask(b) assigned to your in section IP-Protocol:
9. To load the configuration into the CPU select it first go to Online →Download to device and click on
Start search (a) to look for your controller. Then select the controller and click on Load (b):
a
a

The PLC checks the 2311 device ready status and starts a new measurement. Then it stops the
measurement after 3 seconds, read the measurement results, starts a new measurement again and so on.
Note: Make sure that PROFINET Control is enabled in RESISTOMAT®2311. For details, see chapter
Configuration menu in Resistomat 2311 of the RESISTOMAT®2311 PROFINET manual.
1. To control the measurement value just add the variable "Data_block_1".MeasValueAsString to the
watch table and click on the button Monitor all (a)

6 Further Examples
6.1 Writing of string data types
Note: Datatype String in TIA Portal contains two additional bytes, which represent the length of the
string. To avoid these two bytes being sent use the function ‘Strg_TO_Chars’ to convert the String
to a byte array as shown below:
Example 1: Reading Device ID and write it as station name to device
In this example, we perform a write access on slot 30/Subslot 1/index 16 to set the station name of
Resistomat 2311. For this acyclic operation, you will need an instance of a WRREC block. You can see the
new station name in the info menu of Resistomat 2311.
PLC parameters table:
Sourcecode:
Strg_TO_Chars(Strg := 'Station 3',
pChars := 0,
Cnt => #NumBytesWritten,
Chars := #abStationName);
REPEAT
"WRREC_DB"(REQ := TRUE,
ID := 268,
INDEX := 16,
LEN := #NumBytesWritten,
DONE => #Done,
BUSY => #Busy,
ERROR => #Error,
STATUS => #Status,
RECORD := #abStationName);
UNTIL NOT #Busy AND #Done
END_REPEAT;
// Station name as a string
// Position in byte array
// Number of bytes written
// Station name as byte array
// 268: HW-ID for General Settings
// Index 16: Station Name
// Length of data to write
// Write done
// Write not completed yet
// Error
// Status
// Bytes to write

Example 2: Writing of serial number 1 into device order sheet
PLC parameters table:
Sourcecode:
You can see the written serial in the Order sheet menu of Resistomat 2311.
Strg_TO_Chars(Strg := 'SN123456789',
pChars := 0,
Cnt => #NumBytesWritten,
Chars := #abSerial);
REPEAT
"WRREC_DB"(REQ := TRUE,
ID := 268,
INDEX := 76,
LEN := #NumBytesWritten,
DONE => #Done,
BUSY => #Busy,
ERROR => #Error,
STATUS => #Status,
RECORD := #abSerial);
UNTIL NOT #Busy AND #Done
END_REPEAT
;
// Serial as a string
// Position in byte array
// Number of bytes written
// Station name as byte array
// 268: HW-ID for General Settings
// Index 76: Serial number 1
// Length of data to write
// Write done
// Write not completed yet
// Error
// Status
// Bytes to write
