3.5 Communication times

The time required for communication can be displayed as a sequence of processing steps (with corresponding times).
Step Explanation
t0 User program in host starts request to the controller (e.g. controller enable with C0040=1) t1 Software driver (e.g. LECOM-S5) in host converts request data into LECOM-A/B protocol V2.0 and starts the transmission. t2 Serial data transfer to the controller (telegram time) t3 Data receipt of the controller: Processing of request and start of response t4 Response data to host are being transmitted (telegram time) t5 Software driver in host evaluates the response, i.e. the response is converted into the format of the user program. t6 Application program in host gets the result
The time sections t2, t4 and t3 are described in detail in the following:
Telegram time (t2 + t4)
The telegram time comprises the serial communic ation from the host to the controller (t2) and the corresponding response from the controller (t4). The time depends on the telegram type and the baud rate set under C0125.

Technical data
Processing time in the controller (t3)
The processing time in the controller depends on the controller type and the code numbers. This is shown in the following table:
Code numbers Processing time (2102 + controller) [ms]
Series
820X 821X/8200 vector/822X 93XX

1)
35 ms is valid for C0001 = 3. If C0001 = 1 and you write under C0046, access is also possible. However, the processing time is prolonged to 70 ms.
2)
For immediately following write-access procedures, the response times may be up to 50ms.
3)
The code number C0046 can only be read. Use a free code number (e. g. C0141) to select a setpoint. For this, refer to t he 93XX Manual.
4)
This is a typical value. For some codes, the processing times may be longer. For this, refer to the 93XX Manual.

4.2 Mechanical installation

• Remove the keypad from the front of the controller if it is attached.
• Attach the 2101 fieldbus module to the front of the controller. Use the fixing screw, which is
part of the delivery pac kage, to secure the fieldbus module (see Fig. 4-1, pos. 3)
Stop!
Tighten the fixing screw to ensure adequate PE connection of the 2102 fieldbus module.

4.3 Electrical installation

• The communication of controllers 820X and 821X may be disturbed by electromagnetic
radiation. Use an additional PE cable to ensure safe communication (see Fig. 4-1 pos. 13). This is not necessary with the controllers 822X and 93XX.
Installation
(^ 1-1).
Caution!
The bus system continues operation even if the 2102 fieldbus system is disconnected from the power supply because of an error.
If this is the case, the controller cannot be reached by the host.
Stop!
The polarity of the voltage supply must not be reversed, otherwise, the 2102 fieldbus module will be destroyed !
• Voltage supply:
– external 24 V (15 to 30 V) via plug-in connec tors 39 (-) / 59 (+)
or
– internal via the controller (connection by plugging it on).
With 820X it is not possible to have an internal voltage supply via the controller.

4.4 Wiring to a host

This chapter informs you about networking the 2102 fieldbus module using the bus systems RS232 (LECOM-A), RS485 (LECOM-B) or optical fibres (LECOM-LI). The accessories requires are listed in chapter 8.1.
Danger!
• An additional electrical isolation is required if
– a 820X, 821X or 8200 vector controller will be connected to a host – a safe electrical isolation (double basic insulation) to VDE 0160 is required.
• Please observe the following:
– RS232:
The electric al isolation of the RS232 interface (LECOM-A) can be achieved by two 2101IB level converters or another RS232 electrical isolation.
– RS485:
With RS485 (LECOM-B), the 2101IB level converter should be installed to the host if it is not equipped with an appropriately isolated interface.
– Optical fibres:
If two controllers are connected via optical fibres (LECOM-LI) they are always isolated.
• For wiring, the electrical isolation of the supply voltage must be taken into account.
Internal voltage supply
The controllers 822X and 93XXare equipped with a double basic insulation to VDE 0160, additional electrical isolation is therefore not necessary.

For wiring, optical-fibre cables must be prepared:
Installation
Optical-fibre cable preparation
Installation of optical-fibre cables
Installation of the optical-fibre rin g (Fig. 4-7)
The preparation of the optical-fibre cables does not require special tools.
1. Cut cable to length on a rigid surface, e.g. using a knife.
2. For optical-fibre cables with PUR sheaths (read) remove approx. 20 mm (for cables with PE sheaths, removal is not required). With unpolished optical-fibre ends, the max. length is reduced by approx. 20 %.
Therefore, polish the cable end of the optical fibre (grain: P1000).
1. Open pinch-screw joint of the plug.
2. Insert the cable end into the optical-fibre connection as far as possible.
3. Tighten the pinch-screw joint. The bending radius should be at least 30 mm, otherwise the max. optical-fibre cable length will be reduced by typically
50 % per bend.
1. Connect the white optical-fibre connector (transmitter, TxD) on the host to the black optical-fibre connector (receiver, RxD) on the next
controller.
2. Connect the white optical-fibre connector on the controller to the black optical-fibre connector on the next controller.
3. Connect the white optical-fibre connector on the last controller to the black optical-fibre connector on the host.
4. If the optical-fibre cables are longer than 40 m, select the high transmission rate. Switch S1 to ON position. This provides a maximum
cable length of 66 m (with a damping of 150 dB/km).
Note!
Further information on LECOM-LI can be obtained from the Operating Instructions LECOM-LI (see chapter 8.1.4).

5 Commissioning

Stop!
Before switching on the mains voltage check the wiring for completeness, short circuit and earth fault.
When switching on the unit for the first time, observe the following sequence:
1. Switch on the controller and, if necessary, the external supply of the 2102 fieldbus module. – The operating status display for the controller ((^ 4- 2),Fig.4-2pos.5)mustbeonor
blinking.
– The green LED (
2. The transmission speed or LECOM baud rate (C0125)is factor set to 9600 baud. If you require a different value, adjust it via the operating unit.
3. Set LECOM unit address (C0009; see description in chapter 6.2.2) via the operating unit or via the host (default setting: 1).
– If several controllers are interconnected, the addressing via C0009 of the controller must be
different than that of the others. This is the only way for the host to reach a certain controller.
– The values 00, 10, 20, 30, ¼, 90 must not be set since they are reserved for group
addressing.
(^ 4-2), Fig. 4-2 pos. 8) must be on. If this is not the case, see chapter 7.
Commissioning
Tip!
The code numbers C0009 (LECOM controller address) and C0125 (LECOM baud rate) can also be input via LECOM. Please observe that the parameters for the host must be adapted. If C0125 is changed, the host will not recognize the response because the controller already transmits it with the new baud rate.
Next steps for 82XX / 8200 vector
1. It is now possible to communicate with every controller, i.e. all code numbers can be read and all writeable codes, except C046 (frequency setpoint) and C0135 (control word) can also be changed. If the code numbers C0046 and C0135 are to be preselected as well, set C0001 = 3.
2. If the controller is switched on while the operating mode C0001 = 3 is active and the speed setpoint is set to =0, QSP (quick stop) is active. Thus, the drive cannot start in an uncontrolled way. The QSP function can be deactivated by setting bit3 from C0135 to 0.
L BA2102EN
5-1
Page 24
Commissioning
Next steps for 93XX
1. Now you can communicate with each drive, i.e. you can read all codes and change all writeable codes.
2. Set the Lenze parameter signal configuration (C0005) to a value xxx1 to control the controller. For the first commissioning, select the signal configuration 1011 (speed control).
3. Terminal 28 (ctrl. enable=controller enable) is always active and must be on HIGH level during operation (see Operating Instructions 93XX). Otherwise, the controller cannot be enabled.
– With the signal configuration C0005=1011, the QSP function (quick stop) and the CW/CCW
changeover are assigned to the input terminals E1 and E2, and thus they are always active. During operation, E1 must be at HIGH level (see Operating Instructions 93XX).
Tip!
With the signal configuration C0005=xx11, terminal A1 is switched as voltage output. Thus, only the following terminals can be connected via cables: X5.A1 with X5.28 (ctrl. enable) X5.A1withX5.E1 (R/QSP)
4. With signal configuration 1011 (speed control), the speed setpoint can be selected in % of n
under C0141.

6 Parameter setting

The parameter setting for the 2102 fieldbus module comprises:
• Controller parameters which can also be set with the operating units 8201BB or 9371BB.
• 2102 parameters, which can only be accessed via the 2102 fieldbus module.
Only the controller parameters are permanently saved in the corresponding controller. Only the parameters important for the serial communication are listed in the following and in the
code table (see chapter 8.2). For further information about the parameter setting see the Manual or the Operating Instructions of the controllers.

6.1 Parameter sets

6.1.1 82XX parameter sets
The 82XXcontroller is equipped with 2 directly addressable parameter sets. They are addressed by means of a code-digit offset:
• Offset 0 addresses parameter set 1 with the codes C0000 to C1999.
• Offset 2000 addresses parameter set 2 with the codes C2000 to C3999.
If a parameter is only available once (see Operating Instructions 82XX), use the code-digit offset 0. Example:
C011 = maximum field frequency C011 in parameter set 1: code number = 11 C011 in parameter set 2: code number = 2011
Changes of the parameters are automatically saved in the controller (see Operating Instructions 82XX).Process data, for instance control words or setpoints are excluded.
Parameter setting
6.1.2 Parameter sets for 8200 vector
The 8200 vector controllers are equipped with 4 directly addressable parameter sets. They are addressed by means of a code-digit offset:
• Offset 0 addresses parameter set 1 with the codes C0000 to C1999.
• Offset 2000 addresses parameter set 2 with the codes C2000 to C3999.
• Offset 4000 addresses parameter set 1 with the codes C4000 to C5999.
• Offset 6000 addresses parameter set 2 with the codes C6000 to C7999.
If a parameter is only available once (see 8200 vector Operating Instructions), use code offset 0.
Example: C011 = maximum field frequency C011 in parameter set 1: code number = 11 C011 in parameter set 2: code number = 2011 C011 in parameter set 3; code number = 4011 C011 in parameter set 4; code number = 6011
Changes of the parameters are automatically saved in the controller (see Operating Instructions 8200 vector). Process data, for instanc e control words or setpoints are excluded.
6.1.3 Parameter sets for 93XX
The 93XX controllers are equipped with 4 parameter sets for non-volatile storage. Another parameter set is in the user memory of the controller. This is the current parameter set. Only the current parameter set c an be directly addressed. Codes: See Operating Instructions or Manual 93XX. Changes of the current parameter set will be lost after switching off the controller. Code C0003 is for saving the current parameter set. After switching on the controller, parameter set 1 is automatically loaded into the current parameter set.

Parameter setting

6.2 Meaning of individual parameters

6.2.1 Operating mode
82XX / 8200 vector controllers
Code C0001 (operating mode) determines the source (terminal, keypad, LECOM) which writes the frequency setpoint (C0046) and the control word (C0135).
Independently of the selected operating mode C0001, the controller can be inhibited under C0040 via LECOM.
Tip!
Please note that the operating mode C0001 is available in both parameter sets. Thus, C0001 must be set identically in both parameter sets. For LECOM control (C0001 = 3), the operating mode in parameter set 1 applies 1. For terminal control (C0001 <> 3), the operating mode in parameter set 1 and parameter set 2 applies.
93XX controllers
The 93XX controller does not offer an operating mode which can be changed by only one code - as available in the 82XX controller. The 93XX controller is operated via the so-called ” Control codes”. If, for instance, the speed setpoint is to be changed via LECOM, it is necessary to define a control code as source for the speed setpoint input of the speed c ontroller. Select the configuration of the control code so that you can enter the speed setpoint via the 2102 fieldbus module. For further information please refer to the Manual 93XX.

BA2102EN

Page 27
6.2.2 LECOM unit address (C0009)
The LECOM-A/B protocol uses the LECOM unit address to address the controller. The LECOM unit address is set under code C0009 at the controller. The address must only be used once. Thus, each controller must get its own LECOM unit address.The values 00, 10, 20, 30, ..., 90 must not be set since they are reserved for group addressing (see chapter 5).
The LECOM-A/B protocol enables controller groups. This allows a write request to be issued to several drives at the same time, e.g. to select new setpoints or enable or inhibit the controller. Select via the following reserved LECOM unit addresses:
Parameter setting
LECOM unit add ress C0009 for group drives
00 all 10 11 to 19 20 21 to 29 30 31 to 39 40 41 to 49 50 51 to 59 60 61 to 69 70 71 to 79 80 81 to 89 90 91 to 99
LECOM unit addresses of the addresses controllers
Tip!
Please note that with LECOM controller addresses which end with a 0, the controller does not return an acknowledgement, i.e. the host does not recognize whether the controller received the data correctly or not.

6.3 Special features when using the 82XX controller

Tip!
Reading and writing of the parameter C192x of 82XX controllers takes up to 500 ms.
6.3.1 Start with Ctrl. inhibit instead of QSP
• After mains connection with the operating mode C0001 = 3, the drive is in the status QSP.
• With C1920 = 1, the switch-on status is always Ctrl. inhibit, so that the drive can be enabled
by writing C0040 = 1.

6.3.2 Reduction of the response time of the interface
• With active reduced response time, write telegrams (send) are only checked for transmission
errors: – If the telegram is fault-free, a positive acknowledgement (ACK) is sent, otherwise it is a
negative acknowledgement (NAK).
– Only then the value to be written is transmitted to the controller.
• The module can be readdressed under the following conditions:
– With 820X controllers after approx. 230 ms. – With 821X/8200vector/822X controllers after approx. 50 ms.
Stop!
The acceptance of the value by the controller cannot be guaranteed.

6.4 Special features when using the 820X controllers

• Parameter setting (codes exc ept C0046, C0135) is only possible while the controller is
inhibited. Parameters are accepted during controller enable but not saved.
• The TRIP reset function (fault reset) is executed by setting controller inhibit followed by
controller enable via code C0040 or C0135. – The TRIP-reset function performs basic initialization of the 820X controller and the 2102
fieldbus module. Therefore, the TRIP reset command is not ac knowledgedto the host, thus causing its telegram monitoring to react.
6.4.1 Relative setpoint selection C0141 (parameter channel)
• Enter a relative setpoint, which refers to C0011, under C0141.
• Independently of the currently set parameter, C0011 of parameter set 1 is always taken as
reference value.
• The automatic adaption of the relative setpoint in the event of a C0011 change is not
considered because C0011 can only be changed when the controller is inhibited.

The parameter LECOM input selection ensures the compatibility with previous master-system drivers according to the LECOM-A/B specification V1.0. This code is only fully used with 93XX, since this series uses the so-called array parameters, i. e. a code consists of several parameters (e.g. C0039 = JOG with 15 values). Code C0248 determines the array element to be accessed. The functionality of the input selection is simulated (before e.g. C0038).
This input is valid for all LECOM accesses; i.e. the access of a standard parameter with a LECOM input selection that is not 0 results in a fault because the addressed value does not exist.
The array element can be directly addressed via a LECOM-A/B driver as from specification V2.0. This parameter should therefore not be used any longer.
C0248 is included in ever y LECOM code bank (see C0249).
The parameter value is always set to 0 when switching on.

8.3 LECOM-A/B protocol

The LECOM-A/B protocol is used to exchange data between Lenze controllers and a host. The LECOM-A/B protocol is based on DIN 66019, ISO 1745 and ANSI X3.28 (category 2.5 and A2, A4). These standards are similar to each other and desc ribe the control mode of a transmission section of a transmission system.
The host, which is the master, can communicate with a slave (Lenze controller) in three modes:
• RECEIVE (see page 8-21)
• SEND (see page 8-23)
• BROADCAST/ MULTICAST (see page 8-24)
8.3.1 General
The controllers communicate by means of the ASCII code:
0 1 2 3 4 5 6 7 8 9 O B C D I F 0 NUL SOH STX ETX EOT ENQ ACK BEL BS HT LF VT jFF CR SO SI 1 DLE DC1 DC2 DC3 DC4 NAK SYN ETB CAN EM SUB ESC FS GS RS US 2 ÚÛ Ú>Û ÚÒÛ Ú@Û ÚAÛ ÚBÛ ÚCÛ ÚÛÛ ÚEÛ ÚFÛ ÚGÛ ÚHÛ ÚIÛ ÚJÛ ÚKÛ ÚLÛ 3 ÚMÛ ÚNÛ ÚOÛ ÚPÛ ÚQÛ ÚRÛ ÚSÛ ÚTÛ ÚUÛ ÚVÛ ÚWÛ ÚXÛ ÚYÛ ÚZÛ Ú[Û Ú\Û 4 Ú]Û Ú^Û Ú_Û Ú`Û ÚaÛ ÚbÛ ÚcÛ ÚdÛ ÚeÛ ÚfÛ ÚgÛ ÚhÛ ÚiÛ ÚjÛ ÚkÛ ÚlÛ 5 ÚmÛ ÚnÛ ÚoÛ ÚpÛ ÚqÛ ÚrÛ ÚsÛ ÚtÛ ÚuÛ ÚvÛ ÚwÛ ÚxÛ ÚyÛ ÚzÛ Ú{Û Ú|Û 6 ÚÚÛ Ú~Û ÚÄÛ ÚÅÛ ÚÇÛ ÚÉÛ ÚÑÛ ÚÖÛ ÚÜÛ ÚáÛ ÚàÛ ÚâÛ ÚäÛ ÚãÛ ÚåÛ ÚçÛ 7 ÚéÛ ÚèÛ ÚêÛ ÚëÛ ÚíÛ ÚìÛ ÚîÛ ÚïÛ ÚñÛ ÚóÛ ÚòÛ ÚôÛ ÚöÛ ÚõÛ ÚúÛ
Example:
”EOT” =02 Character ”1” =31
hex=2dec
=49
hex
dec
Code number (C1, C2)
Standard addressing
The meaning of the code numbers and the assigned parameters can be obtained from the code table (see chapter 8.2). When transmitting data, the code number are coded as follows:
The following calculation determines the two ASCII digits from the code number (value range: 0 ¼
6229) (value range: 48
C1 = INTEGER((REMAINDER(code number/790))/10)+48
dec
¼ 127
dec
):
dec
C2 = REMAINDER(REMAINDER(code number/790)/10) +
INTEGER(code number/790) x 10 + 48
dec
The INTEGER is the digit before the decimal point, the REMAINDER is an integer. Example: 13/5 = 2 remainder 3
INTEGER(13/ 5) = 2 REMAINDER(13/5) = 3
Example: Convert code number 1002 in ASCII code C1 and C2:
C1
= INTEGER((REMAINDER(1002/790))/10) + 48 =
ASCII
INTEGER(212/10) + 48 =
C2
21 + 48 = 69 = 45
= REMAINDER(REMAINDER(1002/ 790)/10) +
ASCII
hex
= ”E”
ASCII
INTEGER(1002/790) x 10 + 48 = REMAINDER(212/10) + 1 x 10 + 48 = 2+10+48=60=3C
hex
= ”<”
ASCII

Page 49
Appendix
The code number C1002 is converted into the ASCII string ” E<” , if they are transmitted to the controller by a host.
Addressing via code bank
With previous LECOM-A/B drivers, only code numbers in the range from 0 to 255 could have been addressed, since these drivers used only one byte as code number. To achieve the addressing of the wider code-number range with these drivers, use the code banking.The code-number range 0 ¼ 255 is displayed as a window over the whole code-number range. This is controlled via the code C0249 (code bank). Code C0249 can always be accessed via number 249, independent of the currently set code bank.
Assignment:
Code bank Code offset Code-number range
0 0 0 ¼ 255 1 250 250 ¼ 505 2 500 500 ¼ 755 3 750 750 ¼ 1005 4 1000 1000 ¼ 1255 5 1250 1250 ¼ 1505 6 1500 1500 ¼ 1755 7 1750 1750 ¼ 2005
Note: Code banking is only active when the standard addressing is being used. If the selected code numbers are higher than 255, the code-number range increases correspondingly. Only the corresponding code-number offset is selected by means of the code bank.
Example: Set the code bank INTEGER (1002/250) =4 in C0249 to address the code number 1002. C1002 is then accessed via the code number C02.
Addressing via input selection
Simple LECOM-A/B drivers, which only use the standard addressing, cannot address subcodes. The input selection C0248 has been developed to offer the possibility of addressing the subcodes. When using the standard addressing, the value entered in C0248 is always considered as the subcode. The code C0248 can always be accessed via number 248, independent of the currently set code bank and the subcode used.
Example: Enter value 1 in C0248 to address the JOG value 1 in subcode 1. Now subelement 1 is always addressed when acc essing C39.
Tip!
After a subelement has been accessed through C0248, C0248 should be reset to 0 to avoid the addressing of a subelement ” by accident” when acc essing a code.
L _^ONMObk

Extended addressing
Another possibility is the direct addressing of parameters by means of expanded addressing.

shows
A code number range from 0to 65535 can be addressed by means of these characters. Amaximum of 255 subelements (field elements) can be accessed via one subcode number of each code.
Example: 1002 = ”!03EA00”
Parameter value (V1 to Vn)
Parameter values can be transmitted in four different formats with the following structures:
• ASCII decimal format (VD)
- VK1 VK2 VK3 VK4 VK5 VK6 . NK1 NK2 NK3 NK4
• ASCII hexadecimal format (VH)
H VH1 VH2 VH3 VH4 VH5 VH6 VH7 VH8
• String format (VS)

Each character corresponds to a nibble of the data block
Tip!
In the ASCII decimal format (VD), the decimal point must not be transmitted if the value does not have digits after the decimal point.
Parameter value in ASCII hexadecimal format (VH)
The LECOM-A/B protocol supports the transmission of hexadecimal parameter values with a length of:
• 2 characters (byte value)
• 4 characters (wort/integer value)
• 8 characters (double word/long integer)
In the ASCII hexadecimal format, VH1 is the most significant and VH8 the least significant hexadecimal character.
Parameter value in the string format (VS)
By means of the string format (VS) of the protocol it is possible to transmit strings with max. 20 charac ters in both directions. The Lenze controller c an only send the string parameters (e. g. C200).
Parameter values in the octett string format (VO)
The LECOM-A/B protocol includes the octett string format (VO) with which it is possible to transfer data blocks. The character sequence corresponds to the filing in the memory (ascending order), i. e. the charac ter transmitted first is the data block nibble with the lowest address. The data structure of the data block corresponds to the Intel-memory format with the following definition:
BYTE: 1st high nibble
2nd low nibble
WORD: 1st high BYTE
2nd low BYTE
DWORD: 1st high WORD
2nd low WORD

Controller address (AD1, AD2)
One or more bus devices (slaves) can be selected by means of the controller address which is 2 bytes (AD1, AD2) long. The LECOM-A/B protocol supports the broadcast telegrams, i.e. a telegram is sent to a group or all other bus devices. For this, controller addresses are reserved (see BROADCAST, page 8-24). Controller addresses have the following structure:
AD1 AD2
The abbreviations have the following meanings: AD1 ASCII ten-digit of the slave address (0 ¼ 9; 30 ¼ 39 AD2 ASCII one-digit of the slave address (0 ¼ 9; 30 ¼ 39
Block-check character (BCC)
The block-check character (BCC) is used to store the transmitted data and is generated according to DIN 66219 (chapter 3).
Because of the program, the block-check character is generated by a XOR link from the following digits of the SEND telegram:
• it starts with the character directly after the STX control character
• it ends directly after the ETX control character
– BCC can accept the value 00 ¼ FF

Telegram response
The Lenze controller must return an acknowledgement to the host. The only exception is the broadcast telegram. This telegram does not require an acknowledgement.
The Lenze controller sends two types of acknowledgements:
• Positive acknowledgement (ACK = 06
hex
), if:
– no faults occur during the block storage (longitudinal and lateral parity) – a valid command (variable address) has been recognized – the variable value is within the permissible range – the variable value could have been changed
• negative acknowledgement (NAK = 15
hex
), if:
– one of the above listed conditions cannot be met.
• No acknowledgement, if:
– a broadcast telegram is send – the controller address is not correct

8.3.2 RECEIVE
The command RECEIVE is to request parameter values of the Lenze controllers. The code numbers of the requested parameter are transmitted via the RECEIVE telegram using the following structure:
EOT AD1 AD2 C1 C2 ENQ
The abbreviations have the following meanings:
EOT (04 AD1, AD2 Logic unit address of the slave to be addressed C1, C2 Code number (two ASCII characters)
ENQ (05
Structure and meaning of the code numbers (C1, C2) and the controller address (AD1, AD2) are described in the corresponding paragraphs of the chapter SEND (see page 8-23).
Telegram response
The Lenze controller addressed via a RECEIVE telegram generates one of the following responses:

8.3.4 BROADCAST / MULTICAST
In a bus network, the command BROADCAST is to address all devices or a group of devices (multicast) at the same time. The structure of the BROADCAST telegram is similar to the structure of the SEND telegram. The only exception is that it does not return an acknowledgement.
The devices can be selected via their controller addresses. The following controller addresses are reserved for a BROADCAST telegram:

Example for a BROADCAST telegram
All controllers are to be stopped when setting controller enable (code number C40 = 0).
The host send the following BROADCAST telegram:
EOT 0 0 STX 4 0 0 ETX BCC
The controllers do not return an acknowledgement.
8.3.5 Monitoring of the slave response
The master monitors the selected slave. The slave must return a response within a defined time.Under the following circumstances the slave does not return a response to the master (time out):
• The controller address could not be recognized
• A fault (e.g. parity fault) had been detected in one or several characters, including the
charac ter ”ENQ”
• The transmission path is faulty
• A BROADCAST telegram had been sent
• The hardware does not work properly
If the master does not receive a response within a defined period of time, the transmission is tried again. The number of repetitions is limited.
The monitoring time in the master should be approx. twice as long as the maximum response time.
8.3.6 Transmission faults
After a transmission fault, the master can read C0068 and evaluate the communication error in bit 4¼7.
