MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ Preface This document details the specifications for the MODBUS parameters of the "series 84 / 112 / 150 / 200 Lite" unit from ebm-papst. This excerpt differs from the complete document in that the parameters for internal use by ebm-papst are not described here. These parameters are marked by the word "reserved".
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ Change history Version 5.00 Changes Document annex 5.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ 1 Frame protocol Data are transferred using the MODBUS protocol defined in these specifications exclusively in an environment defined as a master/slave system. The orderly progression of data is defined by the master. A slave is required to respond to its command prompt.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ 1.2.1 Command from master A master device is, for example, a PC or a control device. Initial synchronisation: A transmission pause of at least 3.5 bytes is used for initial synchronisation. The following byte is then interpreted as the first byte of a frame (i.e. address). The pause between the individual bytes of a frame may be a maximum of 1.5 bytes.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ CRC L / CRC H A CRC checksum is generated for the complete telegram. 2 15 16 The polynomial for defining the checksum is 1 + x + x + x (i.e. XOR operation on 0xA001). The initial value is 0xFFFF. The low byte of the checksum is transmitted first, then the high byte.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ 1.3 1.3.1 Commands Read holding register Command code: 0x03 This command is used to read out the content of a number of holding registers. Holding registers are parameters for which both read and write access are possible.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ 1.3.2 Read input register Command code: 0x04 This command is used to read out the content from multiple input registers. Input registers are parameters for which only read access is possible.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ 1.3.3 Write single register Command code: 0x06 This command is used to write the content of one holding register. Command from master: 4 data bytes are transmitted: MSB holding register address LSB holding register address MSB data to be written LSB data to be written The holding registers are described below.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ 1.3.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ 1.3.5 Write multiple register Command code: 0x10 This command is used to write the content of several holding registers.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ 1.3.6 Commands with addressing via serial number These commands also use the fan serial numbers for addressing: An identifier for the fan serial number (6 bytes) is transmitted in the data section of the commands. Only the fan that has the MODBUS address and serial number given in the command will react and respond.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ Broadcast addressing If the serial number identifier value 0x00 is transmitted in one or more bytes, the corresponding part of the serial number will not be checked by the fan. All fans with the remaining part of the serial number identifier will then respond. If all bytes are transmitted with the value 0x00, all fans will respond.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ 1.3.6.1 Read Holding Register Addressed By Serial No. Command code: 0x43 This command is used to read out the content of a number of holding registers. Holding registers are parameters for which both read and write access are possible. In contrast to "MODBUS over Serial Line Specification & Implementation Guide V1.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ 1.3.6.2 Read Input Register Addressed By Serial No. Command code: 0x44 This command is used to read out the content from multiple input registers. Input registers are parameters for which only read access is possible. In contrast to "MODBUS over Serial Line Specification & Implementation Guide V1.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ 1.3.6.3 Write Single Register Addressed By Serial No. Command code: 0x46 This command is used to write the content of one holding register. In contrast 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) is used in the serial number.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ 1.3.6.4 Write Multiple Register Addressed By Serial No. Command code: 0x50 This command is used to write the content of several holding registers. 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 parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ 1.3.6.5 Applications Initialising a system All fans have the same address 1 when they leave the factory. So that each fan can be addressed individually, this address must be modified in such a way that each fan is assigned its own separate address when a system comprising several fans is being configured.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ For unknown serial numbers, we recommend the following procedure for implementation in a master device: Set the 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 SerNum screen[0] to [5] = 00 00 00 00 00 00 SerNum screen [s] = start value for s = 0 (year): start value = 0x01 (2001) for s = 1 (week): start
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ Function: When the system is being set up, the fans have to be arranged in ascending order by serial number. This is the prerequisite for ensuring that the automatically assigned MODBUS addresses can easily be correlated with the fans in the system. At the beginning, all fans are set to MODBUS address 0x01.
MODBUS parameters "ebm-papst series 84 / 112 / 150 / 200" _______________________________________________________________________________________ Afterwards, all serial numbers found in the master are sorted in ascending order. Each fan is assigned a MODBUS address via the serial number.
