136 Programming the PFC Using WAGO-I/O-PRO
The PLC browser provides an overview of the real execution times for all
CoDeSys tasks with the command "tsk".
If in a PLC program, operating system functions are used; e.g., for the handling
of "sockets" or the "file system", these execution times are not taken into
consideration covered by the command "tsk".
CTU counter:
The CTU counter operates in a value range of 0 to 32767.
Note the maximum number of write cycles of the EEPROM!
Fieldbus couplers/controllers save some information such as IP addresses and
IP parameters in the EEPROM to make it available after a restart. The memory
cycles of an EEPROM are generally limited. Beyond a limit of approx. 1 million
write cycles, memory can no longer be assured. A defective EEPROM only
becomes apparent after a restart by software reset or power-on.
Due to a bad checksum, the fieldbus coupler/controller then always starts with
the default parameters.
The following functions use the EEPROM:
