the Bus parameter set (see 3-4-2 Setting the Bus Parameters). Increasing
the Watchdog time will consequently increase the Data Control Time
The CS1/CJ1W-PRM21 PROFIBUS DP does not automatically resume nor-
mal operation after an Auto-CLEAR has been initiated. In order to resume
normal I/O data exchange, perform the following sequence.
1. Determine which slave device failed during network startup or data ex-
change. To do this, use the CS1/CJ1W-PRM21 Master DTM Monitoring
User Interface or the slave DTM (see sections 3-7-1 Monitoring the Master
Unit and the Network and 3-7-2 Monitoring Slave Status) to determine the
slave and its type of failure.
2. Remove the cause of the failure.
3. Press the OPERATE Button in the Master Units Monitoring window.
Alternatively, the Master can also be switched to OPERATE from the PLC pro-
gram.
Master Unit and the Network
Both the CS1/CJ1W-PRM21 Master DTM and the Generic Slave DTM provide
special user interfaces to facilitate status debugging and diagnostics determi-
nation. This section and the next will discuss the use and the features of these
diagnosis user interfaces.
The CS1/CJ1W-PRM21 Master DTM Diagnosis - Monitor User Interface pro-
vides a means to
• Monitor the CS1/CJ1W-PRM21 Master Unit status.
• Monitor an overview of the status of all allocated slave devices.
• Monitor standard slave diagnostics.
• Monitor the Unit's Error Log
The Error Log is discussed in section 3-7-3 Using the Error Log.
The information is obtained directly from the Master Unit, using FINS com-
mands. The Master DTM reads the Unit's CIO words from the PLC memory,
as well as the standard slave device diagnostics bytes as received by the
Master Unit.
To open the CS1/CJ1W-PRM21 Master DTM Diagnosis - Monitor User Inter-
face, perform the following steps.
1. Make sure the Master DTM is online with the Master Unit. To go on line,
select the DTM in the Network view, and perform one of the following ac-
tions.
• Select the Device - Go Online option from the main menu, or the DTM
context menu, or
• Select the button from the Tool Bar.
2. A communication channel will be opened through CX-Server. The name of
the DTM in the Network view, will turn to Italic font, to indicate that the Unit
is on-line.
