Figure 3 BM85 With Typical Modbus Devices
Figure 3 summarizes the typical layout of devices at the Modbus ports.
Notes
1.This is an example of a single Modbus master device. The device can access devices on other ports at the same BM85 as well as devices across Modbus Plus.
2.This is an example of a single Modbus slave device. The device is accessible from devices on other ports at the same BM85 as well as from devices across Modbus Plus.
3.This is an example of a Modbus network with multiple slave devices. Any device on the port is accessible from devices on other ports at the same BM85 and from devices across Modbus Plus.
4.This is an example of a Modbus network with one master device and one or more slave devices. The master device can access devices on the same port on other ports at the same BM85 and devices across Modbus Plus. The slave devices are accessible only to the Master on the same port.
