二. The Modbus-Protocol
This chapter contains a short description of the main-features of the Modbus-protocol, to provide a better understanding of the integration of Hiromatics into a Modbus-network. It only contains the basic principles, so if you would like to know more details, please check out to following document:

The Modbus-protocol works on a Master-Slave-basis. This means that there is only one device on the Modbus-network, which is allowed to send requests to other devices. This device is called ‘Master’.
All other devices on the network only respond to requests received from the master and will never initiate a transmission by themselves. These devices are called ‘Slaves’.
The slave who should respond to a request is identified by an address, which is described in the nex
t chapter.
