2 Overview
Festo – GDCP-CMMO-ST-EA-SY-EN – 1301a – English 17
2.4.5 Comparators & messages
The following drive conditions can be ascertained via so-called record messages:
– Position comparator active
The drive is located between two defined positions (in the “Position zone”).
Detailed description section 5.9.1.
– Speed comparator active
The speed is within a defined range.
Detailed description section 5.9.2.
– Force comparator active
The actual force (or torque) calculated via the current is within a defined range.
Detailed description section 5.9.3.
– Time comparator active
The time since the start of the position record is within a defined range.
Detailed description section 5.9.4.
In FCT it can be parameterised so that the presence of these states is signaled via digital outputs.
2.4.6 Record Linking
The record linking function allows records to be linked together: the presence of a defined step en-
abling condition after a record has been executed causes another record to be executed automatically.
Only available in the binary profile. Detailed description section 5.8.
2.4.7 Record switching by PLC
The record switching function enables the PLC to start a new record before an active record has been
completed. Detailed description section 5.7.
2.4.8 Trace
The “trace” oscilloscope function in FCT makes it possible to record drive data over a defined period in
real time, e.g. speeds and contouring errors during a movement.
2.4.9 Firmware update
The Festo Configuration Tool (FCT) enables firmware to be updated. This should only be performed in
accordance with the instructions provided by Festo Service.
2.4.10 Parameter file
After completing parametrisation, you can upload a parameter file from the controller to your com-
puter; doing this creates a backup copy of the parameters in case the controller becomes damaged or
before firmware updates. This includes information about the connected motor, the drive and the para-
meter settings executed. If the CMMO-ST needs to be replaced, you can simply import the parameter
file from the old CMMO-ST into the new CMMO-ST. The new CMMO-ST is then ready for immediate use.
An example of creating a parameter backup file with the web server section 5.3.4.
