DM56A04 FAQ
Share
azman here from malaysia. i am looking a simple display unit that can work with mitsubishi compatible plc. current ly i am using fx2n. the unit will only need to display numbers.
few days back i bough a DM56A04. this is for testing purposes only. if it is work ok i plan to replace all my timer boards. in total i ve more than 50 units running. using plc gives me more flexibility in operations.
so i really need your help to provide some guideline on how to let the plc to display the numbers on the DM56A04. especially on the programming of plc. any example will be much appreciated.
you can contact me at the above email address or simply whatapp me directly
I would also like to help you solve this problem, but I am very sorry! Because we don't know how to write PLC code. But you can debug step by step:
1 Use USB to RS485 to debug DM56A04 through the serial port assistant on the computer
2 Use USB to RS485 to debug PLC and let PLC issue the same instructions
3 Use PLC to debug DM56A04 again
