Posted 21 Apr 2016 Dear colleagues, is it possible to operate two working Modbus units on one PLC (FX3u)? For example, one as serial Master with FX3U-485ADP-MB and another TCP Server with FX3u-ENET-p502? Share this post Link to post Share on other sites
Posted 21 Apr 2016 Yes, using one serial module and one ENET-P502 module. The ModbusTCP function is pure code (a function block), so there won't be any issues with the standard serial Modbus module. Share this post Link to post Share on other sites
Posted 22 Apr 2016 Thank You kaare_t for the answer. What are PLC parameters required (ch1, ch2) in this case? Share this post Link to post Share on other sites
Posted 28 Apr 2016 It would be the same as for any other setup (the ADP card is not affected by the ENET module). Share this post Link to post Share on other sites
