The newcomer doesn’t understand well; please provide the wiring method for connecting a temperature transmitter to a PLC

The term \"temperature-variable wiring system\" can have two meanings: (1) It refers to the three possible scenarios that occur during the supply of power or signal transmission by the transmitter – two-wire system, where power supply and signal transmission are carried out through two wires； Three-wire system: 3 core wires are used, with one dedicated wire for power supply and another for signals, while a common ground wire is shared by both ； 4-wire system, 4-core wires: 2 cores for power supply and 2 cores for signal transmission. 　　　 (II) Refers to the usage conditions during the transmission of signals from the sensor side. Thermocouple temperature measurement usually requires 2-wire wiring (special case: compensation wire) ； Thermistor temperature measurement can use 2-wire wiring, but errors are introduced due to the change in resistance with temperature ； Using 3- or 4-wire wires can eliminate the impact of wire resistance on temperature. However, the cost-effectiveness of 4-wire systems makes them suitable only in specific situations; therefore, three-wire RTDs are commonly used in industry. ********** Regarding wiring methods: Definitions: 1. Transmitter (4–20mA output): Terminal blocks, 1 +; 1 -. 2. 24VDC power supply inside the transmitter: V+; V-. 3. 24VDC power supply inside the PLC: Terminal blocks, 24VDC (+); 24VDC (-). 4. AI module (4–20mA input): Terminal blocks, AI (+); AI (-). For two-wire transmitters, wiring requires items 1, 3, and 4, with the sequence being 24VDC power supply (+) ------- Transmitter 1 + ------ Transmitter 1 - ------ AI module (+) -------- AI module (-) -------- 24VDC power supply (-); this is the most standard configuration for transmitters. For four-wire transmitters, wiring requires items 1, 2, 3, and 4, with the wiring divided into two groups: 24VDC power supply (+) ------- Transmitter’s V+ power supply, and 24VDC power supply (-) ------- Transmitter’s V- power supply; Transmitter 1 + ------ AI module (+), Transmitter 1 - ------- AI module (-). For three-wire transmitters, if it’s an RTD signal, it can be fed directly into the PLC’s RTD module; otherwise, an onboard temperature transmitter can be used to convert it into a two-wire pure AI signal that can then be fed directly into the AI module ； If it is signal-power-common, divide the common terminal into two parallel ones at the wiring terminals inside the PLC, and then connect them using a four-wire system.
