1.1.1 Safety instructions
Protection against dangerous movements
Warning
The connected actuators are subject to high acceleration forces.
Uncontrolled movements can cause collisions which can lead to serious injury.
Dangerous movements of connected drives can be caused, for example, by:
– untidy or faulty wiring
– errors during component operation
– faults in the transducers and signal generators
– defective or non-EMC-compliant components
– faults in the higher-order control system
– programming errors in user programs and projects.
Switching off load voltage is not a proper inhibit mechanism. Unintentional movement of drives
may occur in the event of a malfunction.
•Before carrying out assembly, installation and maintenance work, place the system in a safe
state (e.g. by placing the drive in a safe position and deactivating the controller).
•The power supply must be switched off before working in the area of the machine.
•Make sure that nobody enters the positioning range of the drives or other connected actuators.

CODESYS V3 pbF is supplied with the CECC package for the controller CECC.
2.3.2 Remanent variables
A maximum of 7,120 bytes are available on the CECC for storing remanent variables. They are
automatically shared based on the variable declaration within the application.
The following sample combinations for distributing the remanent memory are possible:
RETAIN variable PERSISTENT RETAIN variable
7,120 bytes 0 bytes (only if there is no PERSISTENT variable list)
0 bytes 7,076 Byte (44 bytes for identification)
300 bytes 7,076 - 300 bytes = 6,776 bytes (44 bytes for identification)
x bytes 7,076 - x bytes (44 bytes for identification)
Note
•
Make sure during programming that the total size of all the remanent data does not exceed the
maximum available range of 7,120 bytes.
This will avoid errors when transferring an application to the CECC.
