How can read value with unknown holding register. it's possible make it with modbus poll? I have light radiation sensor model BGT-JYZ2 but i haven't manual and not find it in internet.
For Modbus communication you’ll require ALL parameters to be 100% correct. Without the holding register nr you cannot make a Modbus connection and read the register. Please contact your supplier for support, manual and Modbus documentation.
Thanks a lot dear bro after watching your video I was able to connect a device to PC with Modbus communication link. thanks once again,
When reading registers on modpoll I can only read one register at a time. So if I put in (PDU144 x3 I get a illegal data address 02)? vs (PDU144 x1)
Is this still an issue? You can check our website www.fluidwell.com/modbus for more information about modbus and our products.
