ACS480 Word and Real Parameters Modbus Mapping
Hi,
I am trying to connect a vfd with AC500 eco PLC. I can read and right binary data with my logic. But I am unable to send frequency reference from PLC to VFD and also can't read holding registers actual values. Can someone please guide here? Need urgent support.
I am unable to access registers by using addressing mode 0 and formula mentioned in that section.
