4.5.3.4 Modbus: Local Slaves
This screen allows enables you to configure local serial Modbus Slaves that will be
accessible via the Modbus/TCP server.
FIGURE 4–50: Serial: Modbus: Local Slaves
This screen is used to define the directly connected Modbus devices. The table below
specifies the parameters you can view and edit in the Serial: Modbus: Local Slaves screen.
Priority (DiffServ): Each IP packet generated by this device will be assigned a
DiffServ Code Point (DSCP) based on the priority set by the user.
The priorities are:
• Default – Best Effort Service (DSCP 0). This is normal
queuing.
• Expedited – Expedited Forwarding (DSCP 0x2E)
(RFC2598). This will also result in data from this
port having a higher priority on WAN ports.
Exception Support: Specify whether or not the attached master understands
Modbus exception messages. In some cases Modbus devices
do not support the exception function codes and will be
confused by them if received. This option allows you to disable
exception forwarding to the master device.
Delete: Set the Delete checkbox in a row in the Existing Devices table
and click Apply Settings to delete that local master.
