Posted 5 Jan 2016 Hello. I have a question regarding NB series display. The comunication is made through RS232 / RS485 comunication. I would like to use NB display as MODBUS MASTER and SLAVE aplication. - Display would work as MADBUS-MOSTER to talk to plc controllers. (Working through COM2 - RS485) - Secondly, Display would work as MODBUS-SLAVE to talk with (SCADA). (Working – Registers LW, LB)) What I have trouble with, is: - I would like to change variable in the PLC - for example : Regime_PUMP (address: 0x0001). - Regime_PUMP variable should be settable from all three devices PLC <-> DISPLAY <-> SCADA So: - If I change Regime_PUMP through PLC it should refresh also on DISPLAY and SCADA. - If I change Regime_PUMP through DISPLAY it should refresh also on PLC and SCADA. - If I change Regime_PUMP through SCADA it should refresh also on DISPLAY and PLC. Does anybody have an example for NB series of display to do this? Best regards. Share this post Link to post Share on other sites
