SQ-300I 8700700-004 Multi-series PLC control system Full supply of spare parts imported from Europe and the United States including fieldbus module (signal input) microprocessor (a redundancy). The wiring harness (two wires per signal) from the marshals (arranged in logical order) terminals transmits the signal to a fieldbus module (FBM) located in another cabinet near a digital device called the fieldbus module that converts the analog input to digital input and transmits it to the microprocessor (controller) via a pair of wires called the field bus.
The fieldbus can also accept and transmit signals from programmable logic controllers (PLCS) and other controllers through appropriate signal conditioning cards. Advances in digital computer systems have led to the emergence of intelligent field transmitters, compared with traditional transmitters, intelligent field transmitters have the following; Outputs are digital signals used to feed directly to downstream digital systems. Analog to digital cards are not necessary. The microprocessor receives process data from multiple transmitters via the FBM card. These cards convert analog data from a field transmitter into a digital signal acceptable to the microprocessor. The microprocessor compares the process value with the set value and sends the correction output via the output card to the field-installed final control element. These convert the digital output into an analog output suitable for field control valves. The processing time for each data is very short, about a few nanoseconds (billionths of a second; Thousandths of a microsecond), enabling the microprocessor to process multiple inputs at once and easily control the process of more than 1,000 cycles. Each tag number has an address. The microprocessor recognizes each field instrument by its address to receive/send signals.
