Universal Robots UR30 - Modbus

12.1. MODBUS
Description Here, the MODBUS client (master) signals can be set up. Connections to MODBUS
servers (or slaves) on specified IP addresses can be created with input/output signals
(registers or digital). Each signal has a unique name so it can be used in programs.
Refresh Push this button to refresh all MODBUS connections. Refreshing disconnects all modbus
units, and connects them back again. All statistics are cleared.
Add unit Push this button to add a new MODBUS unit.
Delete unit Push this button to delete the MODBUS unit and all signals on that unit.
Set unit IP Here the IP address of the MODBUS unit is shown. Press the button to change it.
Sequential
mode
Available only when Show Advanced Options selected. Selecting this checkbox forces the
modbus client to wait for a response before sending the next request. This mode is
required by some fieldbus units. Turning this option on may help when there are multiple
signals, and increasing request frequency results in signal disconnects.
The actual signal frequency may be lower than requested when multiple signals are
defined in sequential mode. Actual signal frequency can be observed in signal statistics.
The signal indicator turns yellow if the actual signal frequency is less than half of the value
selected from the Frequency drop-down list.
Add signal Push this button to add a signal to the corresponding MODBUS unit.
Delete
signal
Push this button to delete a MODBUS signal from the corresponding MODBUS unit.
