4.6 Monitoring the data set online

When the MELSEC-WS safety controller is online and running, you can monitor the
data set online in the network module configuration dialog.
 Click on the GETH Network module [13] button (Network Modules button
when two network modules are used) above the main window and select the
desired Ethernet interface module or double click the desired Ethernet interface
module in the hardware configuration to open the network module configuration
dialog.
 Click on the MELSEC-WS to Ethernet or the Ethernet to MELSEC-WS tab on
the left hand menu to display the routing view for the input or output data you
want to monitor.
For both directions, MELSEC-WS to Ethernet as well as Ethernet to MELSEC-WS,
inactive bits are displayed grey while active bits are highlighted green:
In the MELSEC-WS to Ethernet view, bits that are inactive due to an error are
displayed red. This could be the case e.g. for the outputs of a WS0-XTIO module if
the power supply of this module is faulty:
In the Ethernet to MELSEC-WS view, bits that have no tag name assigned (so that
they can not be used in the logic editor) but which are included in the process image
that the Ethernet interface module receives from the programmable controller, are
highlighted yellow:
The Ethernet interface module always reflects the actual physical status of the
inputs and outputs on the connected modules and devices. This means that even
when Force mode is active and inputs that are physically Inactive (Low) are forced
Active (High) (or vice versa) the actual physical status of these inputs will be
transmitted to the programmable controller instead of the (virtual) forced status. If,
however, as a result of forcing of one or several inputs, one or several outputs
change their status, the changed status of these outputs will be transmitted to the
programmable controller since the actual physical status of the outputs on the
devices has changed.
