Hello everyone, I am inquiring about the type of built-in port that the FX2N-80MR PLC has. Is it equipped with RS232, RS422, or RS485? Additionally, I am looking for recommendations on which module to use for converting to RS232. Also, are there any instructions in the FX2N and FX3U that can perform a PLC restart function?
To connect to the programming port (422) of your PLC, you will need an SC09 cable. This cable is red and has a 25-pin connector, with an adapter for the 8-pin mini DIN to 232 9-pin connection. While there are other options available on the market, most of them are USB equivalents. To program the PLC, you will need to use GXDeveloper or GXWorks, which are the programming Integrated Development Environments (IDEs). The programming port protocol is not usually disclosed. To reset the PLC using GXDeveloper or GXWorks, you will need to stop the program and then restart it via the IDE. Another method is to assign an input to switch on M8037 within the program, which will force the PLC into stop mode. The specific procedure may vary depending on the model of your PLC, as some models have a designated run input while others do not. For more detailed instructions, refer to the manual at https://dl.mitsubishielectric.com/dl/fa/document/manual/plc_fx/jy992d48301/jy992d48301j.pdf.
In response to Parky's advice on PLC programming, the key information is that the programming port is 422 and requires an SC09 cable with a red color and a 25-pin connector. This cable also comes with an adapter for the 8-pin mini DIN to 232 9-pin connection. While there are other options on the market, the recommended ones are generally the USB equivalent. To reset the PLC using GXDeveloper or GXWorks, the protocol for the programming port is not usually disclosed. You can achieve a reset by stopping and then running the PLC via the IDE, or alternatively, by assigning an input to switch on M8037 within the program to force the PLC into a stop. It's crucial to refer to the manual for specific instructions based on your PLC model. If you require enhanced communication flexibility, consider adding a communication module to the left side of the PLC.
There are several boards available, such as the FX2N-232BD and 485BD. There may also be a 422BD board, although these models are likely reaching the end of their production cycle along with the FX2N PLC. However, you can still find them for sale on platforms like eBay or similar websites. Mitsubishi provides manuals for these boards, with the default settings optimized for programmers. You can easily adjust the communication protocol in the PLC's Parameters section. Once you have set up the baud rate and other necessary configurations, ASCII communications become straightforward. The FX2N-232BD board, for example, will populate a set of registers with values for seamless communication. For more information, you can refer to this manual: [link].
Parky mentioned the availability of various boards such as the FX2N-232BD and 485BD, with a possible 422BD option, though they may be nearing the end of their product life cycle along with the FX2N series. These boards can still be found on platforms like eBay. Mitsubishi offers manuals for these boards, with default settings tailored for programmers. However, users can adjust communication protocols in the PLC's Parameters section. Setting up baud rates correctly will enable simple ASCII communications, with the 232 board populating registers for easy data transfer. For more information, you can refer to the manual provided by Mitsubishi: [insert link]. Thank you for the information, Parky.
To activate communication between the board and the PLC, place the board onto the PLC and access or create a project. Navigate to PLC Parameters and select the PLC System2 tab. Check the box for operate communication setting and choose Non-procedural as the communication type. Adjust the remaining parameters accordingly and develop your code within the PLC using the RS instruction. This instruction will fill a series of registers with the data you provide. For instance, if you input "1234 Test" into the RS function at register D100, the data will be stored there along with additional registers. These registers serve as a buffer, with other registers available for details like the number of bytes received (refer to the communication manual). Additionally, a portion of the communication code is included for reference.
Hey there! The FX2N-80MR PLC, as far as I know, does come with a built-in RS422 port. For the RS232 conversion, you might want to look into the FX-232ADP module as it's designed to mediate that changeover. In terms of initiating a system restart, neither the FX2N nor FX3U have an on-board restart instruction. You'll need to externally trigger a power reset for that kind of function. I hope this helps!
