PLC communication module is used to complete with other PLC, intelligent control equipment or other communication between computers. Following a brief introduction FX Series Communication function expansion boards, adapters and communications modules.

(1) Communications expansion board FX2N-232-BD FX2N-232-BD transmission is standard RS-232C connection PLC and other equipment interface boards. Such as personal computers, bar code readers or printers. Can be installed in FX2N internal. Its maximum transmission distance of 15 meters, the highest baud rate of 19,200 bit / s, can be realized using specialized software running on the PLC control, but also convenient from personal computers to send PLC procedures.

(2) communications interface module FX2N-232IF FX2N-232IF connected to the FX2N Series PLC, can be realized with other RS232C interface with a full-duplex serial communication equipment. For example, personal computers, printers, bar code read out and so on. FX2N in the series can connect up to eight modules FX2N-232IF. By FROM / TO directive send and receive data. The greatest transmission distance of 15 meters, the highest baud rate of 19,200 bit / s, occupying eight I / O points. Data length, serial communication baud rate, and so special data register can be set up.

(3) Communication expansion board FX2N-485-BD FX2N-485-BD-for RS-485 communications. It can be used without the agreement of data transmission. FX2N-485-BD in the original agreement means of communication, RS instructions in the use of personal computers, bar code readers, printers, data transmission between. The largest carrier transmission distance of 50 meters, the highest baud rate for the 19200 bit / s. Each FX2N Series PLC can be installed a FX2N-485-BD communication boards. In addition to using this communication boards and computer communications to achieve, but also can be used to achieve two FX2N series of parallel between the PLC.

(4) Communications expansion board FX2N-422-BD FX2N-422-BD used RS-422 communications. FX2N Series can connect the PLC, and as a programming tool or control of a port. This interface can be connected to PLC PLC in the external equipment, data storage units and human-machine interface. Use FX2N-422-BD can connect two data storage units (DU), or a series of DU unit and a programming tool, but one can only connect a programming tool. Each unit can connect a basic FX2N-422-BD, and can not be FX2N-485-BD or FX2N-232-BD used together.

(5) interface module MSLSECNET / MINI

Use MSLSECNET / MINI Interface Module, FX Series PLC can be used in situ A series PLC control station, a distributed control system.
