Line is connected with VPC3+C Communication processor, and VPC3+C Communication processor is connected with Profibus communication port, described micro-control unit
Be also respectively connected with hardware setting interface, 485 interfaces, modbus protocol specific interfaces, IO A/D module and internal reservation interface,
And described Profibus communication port, 485 interfaces, modbus protocol specific interfaces, IO A/D module, internal reservation interface all adopt
Phototube Coupling, described micro-control unit is also connected with power module.
Preferably, power module is DC24V power supply.
The beneficial effect of the present invention is：The side that programmable Profibus bus bridge and remote measurement and control module are freely configured with user
The optimization communication of mode maximum program of formula and interiors of products intelligent processing method and data processing mechanism, using VPC3+C communication
Processor adds ARM or 51 single-chip microcomputers and with inexpensive hardware, is furnished with the MODBUS master station protocol stack of exploitation of controlling oneself and freely leads to
Letter two groups of ports of agreement realize this purpose, can be widely applied to the industrial tele-control system of any Profibus bus
In, solve the equipment waste problem that system upgrade brings, so that product is used more flexible, there is compatible performance, easy to use, company
Connect the feature more than number of devices.
Brief description
Fig. 1 is principle of the invention block diagram.
Specific embodiment
With specific embodiment, the present invention is further elaborated below in conjunction with the accompanying drawings.
As illustrated, a kind of programmable Profibus bus bridge and remote measurement and control module, including micro-control unit (MCU),
Power module, hardware setting interface, VPC3+C Communication processor, Profibus communication port, 485 interfaces, modbus agreement are special
Interface, IO A/D module, internal reservation interface, described micro-control unit (MCU) passes through 8086 buses and VPC3+C Communication processor
Connect, integrated CRC check unit in micro-control unit (MCU), and verification unit, VPC3+C Communication processor is led to Profibus
News mouth connect, described micro-control unit be also respectively connected with hardware setting interface, 485 interfaces, modbus protocol specific interfaces,
IO A/D module and internal reservation interface, and described Profibus communication port, 485 interfaces, modbus protocol specific interfaces, IO AD
, all using Phototube Coupling, described micro-control unit is also connected with power module for module, internal reservation interface, and power module is
DC24V power supply.Programmable Profibus bus bridge and remote measurement and control module are in the way of user freely configures and interiors of products
The mode maximum optimization communication of program of intelligent processing method and data processing mechanism, using VPC3+C communication processor add ARM or
51 single-chip microcomputers and MODBUS master station protocol stack and two groups of communications of FreePort communication of with inexpensive hardware, being furnished with exploitation of controlling oneself
The existing this purpose of cause for gossip, can be widely applied to, in the industrial tele-control system of any Profibus bus, solve system liter
The equipment that brings of level wastes problem, so that product is used more flexible, have compatible performance, easy to use, connect more than number of devices
Feature.
The above is present pre-ferred embodiments, for the ordinary skill in the art, according to the present invention's
Teaching, in the case of the principle without departing from the present invention with spirit, changes, modifications, replacement and change that embodiment is carried out
Type still falls within protection scope of the present invention.
