Read 10 modbus slave

i need to know how read 10 modbsu slave holding register with node red.
Not it same time but by sequencial read.
please help me

Is that 10 devices or 10 registers from 1 device?

If 1 device, what are the addresses - are the all within 100 of each other - or - spaced out across the address range.

I ask because, reading 10 registers from 1 device in one go is more that 10x faster (and much more reliable) than 10 single register reads.
