3.4.5 Performance limits of the device

Note the limits of the device!
→ Data sheet
>
Above-average stress
20878
The following FBs, for example, utilise the system resources above average:
Function block Above average load
FREQUENCY,
PERIOD,
PERIOD_RATIO,
PHASE
Use of several measuring channels with a high input frequency
CAN interface High baud rate (> 250 kbits) with a high bus load
PWM,
PWM100,
PWM1000
Many PWM channels at the same time. In particular the channels as from 4
are much more time critical
INC_ENCODER Many encoder channels at the same time
The FBs listed above as examples trigger system interrupts. This means: each activation prolongs the
cycle time of the application program.

NOTICE
Risk that the controller works too slowly! Cycle time must not become too long!
► When the application program is designed the above-mentioned recommendations must be
complied with and tested. If necessary, the cycle time must be optimised by restructuring the
software and the system set-up.

Watchdog behaviour
1490
In this device, a watchdog monitors the program runtime of the CODESYS application.
If the maximum watchdog time (100...200 ms) is exceeded:
> the device performs a reset and reboots
