The maximum limit for RS232 and RS422 is 1 master and 1 slave. 2012-01-08 · Modbus is still going grow because its simplicity allows it develops to adjust to the Ethernet without major change. Modbus currently one of the main Ethernet protocols applied in automation. The older versions of serial like RS-232 and RS-485 are still around as well. There is a group of fieldbus systems standardizes by the IEC 61158. From €268.22.
A fieldbus functions in the so-called master-slave operation. While the master is in charge of control of the processes, the slave stations work the individual partial tasks. Fieldbuses differ according to their topology (star, line, tree or ring), their transmission medium, and -depending on the type - different transmission protocols (message-oriented procedure or summation frame procedure).
A number of standards are used to support specifically developed fieldbuses including the classic CAN (Modbus and CANopen), RS-485 (PROFIBUS, CC- Link Featuring built-in Ethernet switches, Advantech's Modbus gateways provide transparent connectivity from Modbus/ASCII and Modbus/RTU serial devices to Products 10 - 15 ▻Protocol Description, Solutions and Enablement. • Industrial Fieldbus Protocols . ▫ PROFIBUS, CANopen, DeviceNet, Modbus RTU. ▻These PROFINET Fieldbus gateways provide seamless communication between Fieldbus and Industrial Ethernet and allow different protocol devices to communicate ASICs from Siemens and Profichip, Products from over Modbus Plus.

83] is: • safety,availability and,more generally,dependability Modbus is often classified as a fieldbus protocol but with its various enhancements, particularly Modbus TCP, it has an even wider range of communication applications. One of the reasons for its proliferation is that Modbus is simple and hardy. In comparison to some other protocols, it is not sophisticated but gets the job done.
Networking protocols specify what types of data can be sent, how each type of message will be identified, what actions can or must be taken by participants in the conversation, precisely where
Although Modbus is best for industrial applications, its simplicity allows it to be a useful tool for building automation as well. LonWorks : LonWorks is a communication network protocol useful for building automation applications designed on a low bandwidth, for networking devices through power lines, fiber optics, and other media. The company reckons that Modbus has 7% of the total industrial networking market, followed by DeviceNet and CC-Link, both on 6%, and EtherCat and CANopen, both on 5%. Smaller stakes are held by ASi (4%), Modbus TCP (3%), Ethernet Powerlink, Controlnet, Sercos I and II, and Interbus (all on 2%), and Sercos III (1%). I'm not sure why you are drawing a connection between Modbus and X. Modbus is a communications protocol, while X is the standard way of operating a windowing system over a network. The computer your DCS system is running on would have an X server. The GUI on that computer would use X to display windows (and their contents) on the local monitor.

Before the Modbus RTU can be taken in operation following parameters must be set in the Softstarter: – Parameter Fieldbus interface type set to internal Modbus RTU – Parameter Fieldbus control shall be set to On if the motor shall be controlled by Modbus. Modbus Fieldbus Networking Manual: CANopen Interface 8.
All three are widely used, and according to a Building Operating Management survey in 2011, 62% of respondents had at least one BACnet application; for LonWorks the percentage was 40%, while for Modbus the number was 30%. Modbus is still going strong because its simplicity let it evolve to adapt to Ethernet without significant change. It's now one of the major Ethernet protocols used in automation. The older serial (RS-232 and RS-485) versions are still around as well.

Foundation Fieldbus, Modbus, and HART. It appears that Fieldbus and modbus are RS232/485 based and HART is a digital signal riding on top of the 4-20mA analog signal, but which must be accessed via a modem type device.
These protocols defines real time communication between masters of bus, distributed sensors and actors. They are used for low transmission volumes and low latency applications. Note that Modbus is a protocol which defines frame structure for the messages to be transported over serial lines. RS485 defines electrical specifications.
