Note:
This document is not basic information for the RS232 or RS485 serial interface. Fundamental knowledge of the VABus protocol and the RS232 and RS485 serial interfaces is a prerequisite.
VABus Agile1306/2010
Page 14
RS485 and RS232 Interfaces
In some sections – as an alternative to control via the operator panel – settings and display possibilities are described with the help of the VPlus PC-Software. Here, VPlus communicates with the frequency inverter via the X21-Connection or via an optional CM-232 or CM-485 Communication Module.
If the serial interface of an optional CM-232 or CM-485 Communication Module is connected to a PLC,
then simultaneous access to the frequency inverter from the VPlus PC-Software is no longer possible.
In this case, the connection to the PC can be made via USB with the help of an optional interface
adapter on the X21-Connection.
Warning!
Via the VABus-Communication, a control unit can access all of the frequency inverter parameters.
The changing of parameters, whose meaning is not known to the user, can lead to the
malfunctioning of the frequency inverter and to dangerous situations in the plant.
Caution!
If values are to be written regularly with a high repetition rate, then no entry may be made
to the EEPROM, as it only has a limited number of admissible write cycles (approx. 1
million cycles). If the number of allowed write cycles is exceeded then the EEPROM will be
damaged. See Chapter 8 "Handling of Data Sets / Cyclic ".
RS485-Connection
Frequency inverters can be connected to a bus system using CM-485 Communication Modules. The
bus structure is linear and implemented as a 2-wire line. Up to 247 frequency inverters can be addressed and polled from a bus master via VABus.
The frequency inverters can be parameterized and controlled via the bus system. During operation
data can be requested and set from a PC or PLC.
RS232-Connection
The RS232-Connection allows a point to point connection between the participants.
5.1X21-Connection
The X21-Connection with the RJ45-Connector enables the connection to the RS485 interface of a PLC.

5.2Communication Modules
Direct connection of the CM-232 to a PC or PLC
The CM-232 Communication Module enables a direct connection between a 9-pin D-Sub connector
(X310) of the CM-232 and the serial interface of a PC or PLC.
The configuration of the installed communication module is carried out using the VPlus PC-Software or
using the Operator Panel.
With CM-232 the connection to the PC or PLC is made via a RS232-Connection Line (1:1 occupancy).
Direct connection of the CM-485 to a PC or PLC
For the direct connection between the 9-pin D-Sub Interface (X310) of the CM-485 and the serial
RS232-Interface of a PC or PLC, install an RS485/RS232 interface adapter on the signal line.
The configuration of the installed communication module is carried out using the VPlus PC-Software or
using the Operator Panel.
Attention!
The transmitter and receiver must be set to the same transfer rate (baud rate).
The set baud rate applies to the CM-232 and CM-485 communication modules.
Work Steps:
•Mount the CM-232 / CM-485 Communication Module onto the frequency inverter.
•For the CM-232 Communication Module:
Connect the CM-232 and PC with an RS232-Cable.
•For the CM-485 Communication Module:
Connect the CM-485 with a RS485-Cable to the RS485/RS232 Interface Adapter.
Connect the RS232-Connection of the Interface Adapter with the PC/PLC.
Setting the type of Protocol
The factory setting of the CM-232/CM-485 Communication Modules is the BONFIGLIOLI VECTRON
standard protocol (VABus). Communication with the VPlus PC-Software is only possible using this protocol.
The VABus protocol enables the operation of a straight Master/Slave-System. The Bus-Master can be
a PC, a PLC or any arbitrary computer system.
5.2.1Installation Notes
•For the RS485 bus cable use a twisted, shielded cable.
•Implement the shield as a braided shield (not a foil shield).
•Connect the cable shield surfaces at both ends to PE.
•The connector pin assignments of an RS485-Cable and an RS232-Cable are different. No data
transfer is possible if the wrong cable is used.

5.2.3RS485 Bus Termination
Attention!
The passive bus termination (connection of a termination resistor), is required at the physically first
and last client. It can be activated by the CM-485 and CM-485T DIP Switch S1.
By default, the bus termination is set to OFF.
It is important to implement a correct termination. Otherwise, no communication is possible via the
RS485-Interface.
As an alternative, the active bus termination is possible via a corresponding circuit:
+5 V
330
Ω
Data line A
Data line B
The active termination is only allowed once on each branch. The bus termination via an external circuit and via DIP switch at the same time is not allowed.
Pay attention to the ground wiring. This will protect the communication bus against high noise level.
For easy wiring the signal terminals A and B have parallel contacts.

7Protocol
The VABus protocol is the standard protocol of BONFIGLIOLI VECTRON. It defines and describes the
communication via the RS232 / RS485 serial interfaces.
By default, the slot for an optional Communication Module and the X21-Connection are set to the
VABus protocol. The setting can be changed via Parameter
“Set the Protocol for X21-Connection and Communication Modul”.
The VABus protocol enables the operation as a pure Master/Slave system. A PC, a PLC or any type of
computer system is the bus master.
The transmission protocol corresponds to the ISO standard 1745 for code-based information transfer
and applies to the X21-Connection and the CM232 and CM-485 Communication Modules.
Two types of request are used:
− Send Request (Enquiry Telegram) for the request for reading parameters in the frequency inverter
by the bus master.
− Setting Request (Select Telegram) for handing over parameter values or parameter settings to the
frequency inverter by the bus master.
Protocol (CM/X21) 395. See Chapter 5.4

7.2.2Data Types
The number of data bytes depends on the type of the corresponding parameter. A maximum of 99
data bytes can be transferred.
Data Types Used

Parameter values with decimal places are transferred without the decimal point. Depending on the
number of decimal places, the values are multiplied by 10, 100 or 1000.
The number of decimal places for the corresponding parameters is set in the frequency inverter. In
this way it is made sure that the sent parameter values are processed with the correct number of
decimal places.
Example: Frequency value with data type Long:
Value to be transferred = 100.25 Hz. The numerical value transmitted in the telegram is 10025, which
corresponds to 0x2729 in HEX format. Since the data type is Long, 8 bytes are transferred
("wwwwwwww").
00002729
Example: Current value with data type Int:
The value to be transmitted is 10.3 A. The numerical value transmitted in the telegram is 103, which
corresponds to 0x67 in HEX format. Since the data type is Int, 4 bytes are transferred ("wwww").
0067
7.2.3Send Request / Enquiry Telegram
Via the enquiry telegram of the bus master, the frequency inverter is requested to send the data content of the relevant parameter. In the enquiry response telegram, the frequency inverter sends the
requested data to the bus master. The master completes the transmission with EOT.

7.2.8Data Set
The data set limits change depending on the information direction. The data set number is transferred
as an ASCII_character:
The parameter number is always transferred as 3 ASCII characters. If the parameter number is greater than 999, the first position (hundred) is converted to "A" to "F".
Numerical values are represented by ASCII-HEX characters. The value is first of all converted to HEX
notation and then, for each position transferred to ASCII charters.

Each data frame with parameter values is finished via the EXT character (0x03).
7.2.12Binary Checksum (BCC)
The binary checksum (BCC) is made up of a byte which contains the ExOR operation of all bytes between STX (exclusive) and ETX (inclusive).
Only telegrams with parameter values are extended by the binary checksum. Enquiry, ACK and NAK
telegrams do not have a checksum.

7.3Telegram Check / Error Acknowledgement
The frequency inverter and the bus master check the telegrams for correctness. Depending on the
type of telegram, the corresponding reaction takes place. The telegrams are checked for correct syntax, address and text part (content, checksum).
In case the telegram contains errors, the frequency inverter either returns NAK or it does not respond
at all. The possible causes are listed below:
No response:
− incorrect telegram structure
− incorrect control character
− wrong address
− telegram addressed to address 32 (Broadcast); in this case the frequency inverter does not reply

7.4Monitoring Function (Timing / Watchdog)
The protocol defines a pure Master/Slave operation. If a frequency inverter is addressed by the bus
master, other frequency inverters will only be addressed after the protocol with the first frequency
inverter has been completed or the timeout time has expired.
After a frequency inverter has sent a telegram, a waiting time of 2 ms must be kept (t_pc_delay),
which the frequency inverter requires in order to switch off the RS485-Transmitter. The bus master
may not send a new telegram until this time has elapsed.
The frequency inverter replies 1 ms after receipt of a telegram (t_fu_delay) at the earliest. This means
that the bus master must have switched off its RS485-Transmitter after 1 ms at the latest.

Attention!
X21: VABus Watchdog Timer
CM: VABus Watchdog Timer
If the CPU utilization is high (> 90%), then the response time can be more than 500 ms.
Note:
The specified times are valid for operation with RS485 and RS232.
Protocol
If the frequency inverter has not received a character after 500 ms, it rejects the character string
received so far and waits for a new transmission.
If the frequency inverter is operated via the serial interface (RS232, RS485), it may be important to
monitor the presence of the communication line. For example it may be that the frequency inverter is
switched on/off in Remote Mode, or it only receives its reference value cyclically via the serial interface. If the communication fails, no or faulty data are transmitted. This is recognized by the communication watchdog.
The watchdog function monitors the time in which no correct communication takes place.

7.5Block Access
If a number of parameters are to be transmitted regularly block by block, a block transmission can be
carried out using the pseudo parameter described here. Since this type of block transmission only
requires one communication overhead it can be carried out faster and may be easier to implement.
The error evaluation and diagnosis for this block access is more difficult than for a separate parameter
access.
The block definition has to be written in the parameter

written on the parameter
parameters of the type word and/or double word can be transferred during block transmission. The
check sum is calculated (like a separate parameter access) from SYS and ETX (both inclusively). Each
transmission is responded by the frequency inverter with ACK or NAK.

Note:
For the read access of data set dependent parameters BONFIGLIOLI VECTRON recommends reading
the parameters separately for each data set.
If a data set-dependent parameter with data set 0 (= all data sets) is read and the values in the data
sets are different from each other the response of the frequency inverter must be evaluated accordingly. A failed operation can be recognized by the number of bytes = 99.
With block transmission, parameters with data type "string" cannot be transmitted.

Handling of Data Sets / Cyclic Writing
8Handling of Data Sets / Cyclic Writing
Access to the parameter values is carried out on the basis of the parameter number and the required
data set.
There are parameters the values of which exist once (data set 0) as well as parameters the values of
which exist four times (data set 1...4). These are used for data set change-over.
If parameters which exist four times in the data sets are set to data set = 0, all four data sets are set
to the same value.
A read access with data set = 0 to such parameters is only successful if all four data sets are set to
the same value. If this is not the case, error 9 = "different values in data sets" is signaled via the error
register
the relevant parameter (see chapter 7.3 “Telegram Check / Error Acknowledgement”).
New setting requests (select telegrams) will be blocked by the error register
ter
telegram can be sent.
Regardless of the signal status of the error register, reading access (enquiry telegrams) is still possi-
ble.
The values are entered into the EEPROM automatically on the controller. If values are to be written
cyclically with a high repetition rate, there must be no entry into the EEPROM, as it only has a limited
number of admissible writing cycles (about 1 million cycles).
VABus SST Error Register 11. In this case, you must read out each data set separately for
VABus SST Error Regis-
11. For this reason, the error register must be read out, i.e. acknowledged, before a new select
Caution!
If the number of admissible writing cycles is exceeded, the EEPROM is destroyed.
In order to avoid the destruction of the EEPROM, data which are to be written cyclically can be entered in the RAM exclusively without a writing cycle on the EEPROM. In this case, the data are volatile,
i.e. they are lost when the supply voltage is switched off (Mains Off). They must be written into the
RAM again after the restart (Mains On).
The RAM writing operation is activated by increasing the number of the target data set by five.

Local/Remote 412 are described in the frequency inverter operating instructions. These relate
to the control via the Operator Panel and the control via digital signals.
Parameter
Local/Remote 412 is data set related, i.e. by selecting a data set, you can switch over
between the different operation modes.
414 Data Set Selection
The data set switch-over can be carried out via control contacts at the digital inputs of the frequency
inverter or via the bus. For data set change-over via the bus, parameter
Data Set Selection 414 is
used.

The currently selected data set can be read out with Parameter
Active Data Set 249. Active data set
249 states the activated data set with the value 1, 2, 3 or 4. This is independent of whether the data

If the operation mode "Control via Remote Contacts" is used, then the Controller Release
"STOA+STOB" must be switched on and bit 0 of the Control Word must be set, in order to start the
drive.
With the use of Remote Contacts the signal sources (digital inputs or multifunctional inputs set as
digital inputs) are taken virtually from the
Control Word 410. Signals at the hardware terminals are
not evaluated in the standard operation modes (e.g. 72 - IN2D).
Operation modes which are marked with the extension "(Hardware") are available in order to evaluate
signals at the hardware terminals.
Exceptions: The release must always be made via the Hardware-Inputs STOA (Terminal X11.3) and
STOB (Terminal X13.3) and bit 0 "STOA+STOB" of the Control Word.
A Controller Release by software alone is not possible.
