In stock: Delivery 1 - 3 days
BK7350 “Compact” Bus Coupler with compact housing connects Modbus bus system with modular, extendable electronic terminal.
A unit consists of a bus coupler, any number from 1 to 64 terminals and one end terminal.
With the K-bus extension, up to 255 bus terminals can be connected.
The bus switch recognizes the terminals to which it is connected and performs the assignment of inputs and outputs automatically to the words in the process image.
The first input / output signal will be added to the first bit of a word (LSB), starting from the left.
The bus coupler adds additional signals to the word.
A clear separation is maintained between inputs and outputs.
If the number of inputs or outputs is greater than 16 bits, the bus connection automatically starts a new word.
Modbus has a line topology based on the RS485 interface.
The Modbus protocol has been published.
The BK7350 supports the RTU and ASCII protocols.
The baud rate is variable and can be set directly via the rotary selection switch on the bus coupler, ie. without configuration software.
Modbus Bus Coupler supports various Modbus functions that provide direct access to digital and analogue signals.
The BK7350 also supports the Modbus diagnostic function, which allows errors to be detected and counted.
In addition, the bus connection diagnoses faulty or faulty telegrams and responds to the controller with an error.
BK7350 makes it possible to send access, which means that several bus switches can be addressed simultaneously with a single telegram.
BK7350 “Compact” Bus Coupler with compact housing forewinds Modbus bus system with the modular, extendable electronic terminals.
A device consists of a BusCoupler, any number from 1 to 64 terminals and an end terminal.
With the K-bus extension, up to 255 terminals can be connected.
