Data communication between analog modules

Buffer register (BFM) allocation

FX series PLC basic unit and FX - 4AD, FX - 2da etc. analog module between data communication is performed by the from and to instructions, communication modules plc ,from is basic unit reads data from the FX -- 4AD, FX - 2da instruction, the TOS are from the basic unit writes the data to the FX -- 4AD, FX - 2da instruction. Actually read and write operations are FX - FX, 2DA - 4AD buffer register BFM.

This buffer register consists of 16 registers of 32 bits, plc communication modules ,numbered #31 1 BFM#0.

PLC analog input and output module

Q: now need to add equipment such as temperature measurement system, there are two analog modules PLC, 8*12BIT and AI were AI 8*TC, two plc analog input output module . I am alsoJust contact this thing, cannot read what is the meaning of. Please explain.

A: depends on your temperature element type, TC this is only if the thermocouple, thermal resistance can not.
Of course, you can choose a set of temperature transmitter parameters, converting the thermocouple and thermal resistance signal for 4~20mA, communication module plc and then to the general AI module You can.
