RMC70/150 and RMCTools User Manual
Bit Description
0
Connection Established.
This bit will be set when the PROFIBUS interface
is in the Data Exchange mode.
Event Log
The Event Log Monitor can be used to view the PROFIBUS data. By default, the Event Log
only records the changes in the PROFIBUS connection state or address. However, the
Event Log Filter can be configured to make a log each time there is a change in the data
sent from the PLC to the RMC.
Using the Event Log for the I/O Modes
To log the incoming PROFIBUS data, set the Event Log Filter as follows:
1. In the Project pane, right-click Event Log and choose Properties.
2. Click the Communications folder and click PROFIBUS.
3. Check the I/O Mode Data Logging and click OK. The Event Log will now log an
entry each time the PROFIBUS data changes and will display the data.
Using the Event Log for the Basic/Enhanced Modes
See the topic for the respective Basic/Enhanced mode for details.
Communication Statistics
The Communication Statistics Window provides information on the PROFIBUS settings and
connection, including which parameterization and configuration data was last sent to the
RMC.
PROFIBUS Timeouts
How long will it take for the RMC to detect that the PROFIBUS connection is
broken?
This is controlled by the PROFIBUS master.
Specifically, when the master sends the Set_Parameters message as one of the
required steps to enter DATA-EXCHANGE mode with the slave device, the second and
third bytes in that parameterization are called WD_Fact_1 and WD_Fact_2. These two
8-bit values are multiplied together and then by 10ms to give a timeout value.
Therefore, the master can make this value as short as 10ms and as long as 650
seconds (>10 minutes!).
The user must determine how to set this value for their particular PROFIBUS master.
6.9.3. Configuration
6.9.3.1. PROFIBUS Configuration
The following steps are required to connect an RMC unit to a PROFIBUS network:
1. Set the RMC's station address
RMC75P
On the front panel of the RMC75P, use a small screwdriver to turn the rotary
switches to the desired values. The address is the sum of the value of each switch
times its respective multiplier. Use any station address between 1 and 99. Zero (0)
is not allowed as a station address. Since the station address 1 is normally used for
the master, Delta recommends not setting the address to 1.
