Both analog and discrete values are fetched from a PLC via RS485 2W MODBUS. How much time does it take to read value for analog (numeric) value and digital (holding register) value till the values are displayed in DCS system?
I read somewhere that it takes 5 sec for numeric and 1 sec for discrete value.
What effect it will have if several devices are put using multidrop.
Can anyone confirm this?
