I know that we can connect from a modbus Master station to many Slave station by different station ID. Can we connect many modbus Master to many modbus Slave station with different ID form the same piece of RS485 cable (4-wire)?
Example: Master A will acquire data from Slave ID 1, 2 ; Master B will acquire and send data to Slave ID 3, 4 and 5; and even Master C will acquire from Slave 1, 5 and 7.
If yes, will the single hardwire connection cause the traffic congestion. or any other hidden problems might occur?
Thanks.
