Description du protocole de communication Modbus:

Modbus protocol is based on the hardware interface RS485 communication protocol, it can realize networked control point to multipoint. The specific content of the agreement may refer to GB/Z 19582, protocol is divided into RTU and ASCII protocol. The company provided the product is follow the RTU based on Modbus protocol, allows the datas to exchange between the slaves and a master.Communication methods using questions and answers type (that is, the master command, at the request of the analysis is in accordance with the communication agreement, after receiving the slave, if it do reply).

Baud rate:. 4800bps 9600bps (default) 19200bps 38400bps 115200bps….

Frame format: 8 data bits, 1 stop bit, even parity, no flow control

ⅰ. The communication agreement between master-slave machine:

Le maître envoie chaque trame de données doit contenir les informations suivantes (hexadécimales)

The address of the slave / Command word/ Information words/Check code

Slave address (1 byte) :the Slave’s number of equipment. From the address of the slave, the master identify communication equipment. That set by the user address, slave will receive information sent by the master. In a Modbus network ,each of the slave must have a unique address code, and can only respond to meet address code from the slave.

Mot de commande (1 octet) : The master sends the function of code,than it inform the slave of the tasks.

Information word (N bytes) : Including different addresses of the data, the length of the data ,and the data’s information between the communications of the machines.

Vérifier le code (2 octets) :Because used to detect data communication is error, using cyclic redundancy CRC16 check.

ⅱ. Communication parameter setting:

Communication Address: Dans un réseau de communication, l'adresse de l'esclave peut être définie sur 1 ~ 247. (la valeur par défaut est 1)

Vitesse de communication: In a communications network ,the network communication speed can be choosed communication baud rate to 9600, 19200, 38400, 19200, 38400. (default is 19200)

Format des données: Définition du format de données dans un réseau de communication: un bit de démarrage, 8 bits de données, 1 bit d'arrêt, un bit de parité.

Protocole de communication: Le protocole de communication ModBus RTU.

ⅲ. Message format

Command word 03H: reads the parameter value

The requests of the master: address/ command word/ the address of the parameter/ the length of the data/ check code

The responses of the slave: address/ command word/the length of the byte /the parameter value/ check code

Command word 04H: read the measured values

The requests of the master: address/ command word/ the address of the data/ the length of the data/ check code

The responses of the slave: address/ command word/the length of the byte /the data information/ check code

Command word 08H: diagnostic

The requests of the master: address/ command word/ subfunction/ the data information / check code

The responses of the slave: address/ command word/ subfunction /the data information/ check code

Command word 10H: modify the parameter values

The requests of the master: address/ command word/the address of the paramete / the length of the data/ the length of the byte/ the parameter value / check code

The responses of the slave: address/ command word/ the address of the paramete / the length of the data / check code

Precaution:

  • Encoder belongs to precision device, do not pound or knock the encoder,Light handling, using carefully.
  • Ensure the power supply of encoder operate in the rated scope. Insulation must be ensured to avoid the impact to encoder due to the large electric activation in electric network. ;
  • With the strong electromagnetic interference, extended signal line should be special line recommended, such as shielded twisted pair cables.
  • Ensure good grounding of encoder signal line. When close distance within 2m, grounding for the two ends of shield net inside the cable; while lone distance, grounding for the metal housing of encoder. Encoder built-in shielded cable network suspends, single grounding for extended signal shielded cable network at the receiver termination of signal. If the signal cable is too long or being used outdoors, the iron pipe should be covered on the signal cable, and the two ends of metal pipe should grounding.
  • Protection class of encoder is IP65, with water-proof. But do not souse the shaft of encoder.;
  • Special flexible coupling should be selected for connection between encoder and machinery, and F6022 is recommended.
