jo2ham Posted March 15, 2015 Report Posted March 15, 2015 Hi I want to use FX3U as Modbus slave. I am using 485-ADP MB and successfully communicated as slave device. Now my master is able to access all my registers. But I want my Master to access only D1000 to D1100 registers. How can I do this? Please help me out. Thank You Joshua Quote
kaare_t Posted March 15, 2015 Report Posted March 15, 2015 In the FX Series Modbus Communication Edition manual (JY997D26201), in section 9.4 ("User defined MODBUS Deveice Address Assignment) you can read all about limiting the access areas from the default (all access) settings. You need a little logic to make it work, but just follow the examples in the manual... Quote
jo2ham Posted March 17, 2015 Author Report Posted March 17, 2015 Thank you for the reply. Let me try and give the feedback Quote
jo2ham Posted March 18, 2015 Author Report Posted March 18, 2015 I worked as per the example in the manual. But it's not working for me. If any one have any worked out example please give me. Thank You Joshua Quote
kaare_t Posted March 18, 2015 Report Posted March 18, 2015 Could you post what you have done so far? It's a bit hard to help you with your code without seeing it... Pictures of all the code would be nice. Quote
