Slave Status Overview
The Master Status 1 box indicates the Master Unit's status. The Master Sta-
tus 2 box and the Unit Status box all indicate errors. These LED indicators are
discussed in section 7-4-2 Troubleshooting the Network using CX-Profibus.
The Slave Status box indicates the overall status of the allocated slave
devices.
Main indicators in this box are the LED indicators for operational status of the
Master Unit. They indicate whether the Master Unit is in
• OFFLINE mode,
• STOP mode,
• CLEAR mode, or in
• OPERATE mode
The Data Exchange LED indicates if I/O data exchange is taking place with at
least one slave device.
The Auto Clear enabled LED and Valid Configuration LED provide feedback
on the I/O configuration downloaded to the Unit.
The figure below shows an example of the Master Status tab, in the case of a
fully functional network, i.e. there are no errors and all slave devices are
exchanging I/O data with the Master Unit.
The Slave Diagnostics Received LED indicates if any of the allocated slave
device have returned diagnostics information to the Master Unit. In order to
determine which slave reported diagnostics, select the Slave Status tab next
to the Master status tab.
The CS1/CJ1W-PRM21 Master DTM Diagnosis User Interface provides a
comprehensive overview of the slave device status, without having the user to
open all the slave DTMs. The overview is presented in the Monitoring - Slave
Status tab of the user interface, and displays only the standard PROFIBUS
