MODBUS ACE V1.00 _______________________________________________________________________________________ 1 Protocol frame Data transmission using the MODBUS protocol defined in this specification takes place solely in an environment defined as Master - Slave system. The ordered flow of data is governed by the master. A slave has to respond to a command request from the master. When structuring a system, it is therefore important to ensure that a slave address is not allocated twice.
MODBUS ACE V1.00 _______________________________________________________________________________________ 1.2.1 Command from master A master device is a PC or a control unit, for example. Start synchronization: Start synchronization is provided by a silent interval of at least 3.5 bytes. The next following byte is then interpreted as the first byte of a frame (i.e. address). The interval between the individual bytes of a frame must not exceed 1.5 bytes. Address: The size of the address field is 8 bits.
MODBUS ACE V1.00 _______________________________________________________________________________________ CRC L / CRC H A checksum CRC is formed across the entire telegram. 2 15 16 The polynomial for checksum formation is 1 + x + x + x (i.e. XOR operation with 0xA001). The start value is 0xFFFF. The low byte of the checksum is transmitted first, then the high byte. Further information on calculating the checksum can be found in the "MODBUS over Serial Line Specification & Implementation guide V1.0". 1.2.
MODBUS ACE V1.00 _______________________________________________________________________________________ 1.3 1.3.1 Commands Read holding register Command code: 0x03 The content of several holding registers can be read out with this command. Holding registers are parameters for which both read access and write access exist Command from master: 4 data bytes are transmitted: 1. Holding register address MSB 1.
MODBUS ACE V1.00 _______________________________________________________________________________________ 1.3.2 Read input register Command code: 0x04 The content of several input registers can be read out with this command. Input registers are parameters for which only read access exists. Command from master: 4 data bytes are transmitted: 1. input register address MSB 1.
MODBUS ACE V1.00 _______________________________________________________________________________________ 1.3.3 Write single register Command code: 0x06 The content of one holding register can be written with this command. Command from master: 4 data bytes are transmitted: Holding register address MSB Holding register address LSB Data to be written MSB Data to be written LSB The holding registers will be described later.
MODBUS ACE V1.00 _______________________________________________________________________________________ 1.3.4 Diagnostics Command code: 0x08 The MODBUS function can be checked with this command. Command from master: The following data bytes are transmitted: Subfunction code MSB Subfunction code LSB 1 - 17 data bytes Only the subfunction code 0000 is supported.
MODBUS ACE V1.00 _______________________________________________________________________________________ 1.3.5 Write multiple register Command code: 0x10 The content of several holding registers can be written with this command.
MODBUS ACE V1.00 _______________________________________________________________________________________ 1.3.6 Commands with addressing by serial number These commands additionally use the serial numbers of the fans for addressing: An identifier for the serial number of the fan (6 bytes) is transmitted in the data area of the commands. Only the fan with the MODBUS address and serial number specified in the command reacts to the command and responds.
MODBUS ACE V1.00 _______________________________________________________________________________________ Broadcast addressing If the value 0x00 is transmitted in one or more bytes of the serial number identifier, the corresponding part of the serial number will not be checked by the fan. All the fans which have the rest of the serial number identifier will then respond. All fans respond if all bytes are transmitted with the value 0x00.
MODBUS ACE V1.00 _______________________________________________________________________________________ 1.3.6.1 Read holding register addressed by serial no. Command code: 0x43 The content of several holding registers can be read out with this command. Holding registers are parameters for which both read access and write access exist. Contrary to "MODBUS over Serial Line Specification & Implementation guide V1.0", the fan also responds to a broadcast command (MODBUS address = 0).
MODBUS ACE V1.00 _______________________________________________________________________________________ 1.3.6.2 Read input register addressed by serial no. Command code: 0x44 The content of several input registers can be read out with this command. Input registers are parameters for which only read access exists. Contrary to "MODBUS over Serial Line Specification & Implementation guide V1.0", the fan also responds to a broadcast command (MODBUS address = 0).
MODBUS ACE V1.00 _______________________________________________________________________________________ 1.3.6.3 Write single register addressed by serial no. Command code: 0x46 The content of one holding register can be written with this command. Contrary to "MODBUS over Serial Line Specification & Implementation guide V1.0", the fan also responds to a broadcast command (MODBUS address = 0) provided that no broadcast identifier (0) was used in the serial number.
MODBUS ACE V1.00 _______________________________________________________________________________________ 1.3.6.4 Write multiple register addressed by serial no. Command code: 0x50 The content of several holding registers can be written with this command. Command from master: The following data bytes are transmitted: Serial no. byte 1 Serial no. byte 2 Serial no. byte 3 Serial no. byte 4 Serial no. byte 5 Serial no.
MODBUS ACE V1.00 _______________________________________________________________________________________ 1.3.6.5 Applications Initialization of an installation All ex works fans have the same address 1. To be able to address each fan individually in the case of an installation made up of several fans, this address has to be changed so that each fan has a different address. Standard procedure (command 0x06 Write single register): 1. Switch on the first fan (leave all others switched off) 2.
MODBUS ACE V1.00 _______________________________________________________________________________________ The following algorithm is recommended for implementation in a master device if serial numbers are not known: Set Modbus address of all fans to 1 (broadcast): 00 06 D1 00 00 01 CS CS 00 06 D0 00 00 02 CS CS s = 5; i = 1 Mask SerNo[0]..[5] = 00 00 00 00 00 00 Mask SerNo [s] = Start value for s = 0 (year): Start value = 0x01 (2001) for s = 1 (week): Start value = 0x01 (W1) for s >= 2 (consec. no.
MODBUS ACE V1.00 _______________________________________________________________________________________ Procedure: On setting up the installation, the fans must be arranged in the ascending order of their serial numbers. This is necessary to ensure simple assignment of the automatically allocated MODBUS addresses to the fans in the installation. To start with, all fans are set to the MODBUS address 0x01.
MODBUS ACE V1.00 _______________________________________________________________________________________ All the serial numbers found are then sorted in ascending order in the master. A MODBUS address is allocated to each fan by way of the serial number.
MODBUS ACE V1.00 _______________________________________________________________________________________ 2 Holding registers 2.1 Overview The holding registers are stored in the RAM and in the EEPROM of the fan.
