Modbus Communication Chapter 14
Example Architectures Some examples of how the CR30 is used with Modbus are shown in Figure 114 .
In the example below, a PanelView C600 is connected to the serial port of the
CR30. The C600 is configured over its Ethernet port. The C600 can read status
information from the CR30 and can send reset and restart signals to the CR30.
Figure 114 - Modbus RTU Communication — PanelView C600
In this example, a Micro830® is connected to the CR30 by the 8-pin DIN serial
port connections. The Micro830 can read/use status information from the CR30
and can send reset and restart signals to the CR30.
Figure 115 - Modbus RTU Communication — Micro830
In the example below, a PanelView C600 is connector the serial port of the
Micro830 and the Micro830 is connected to the CR30 through a SERIALISOL
plug-in module. The Micro830 can read/use status information from the CR30
and can send reset and restart signals to the CR30.
