____________________________________________________________________

To release CPU time, we need to increase the polling of ETCP and ISaRSI tasks.
On Windows NT, use specific command lines to launch the ETCP or ISaRSI task manually and then launch the Configuration manager (ISaGRAF):

ISaRSI -def=com1:19200:N:1 -CycleTime=22
ISaGRAF -NOETCP

ETCP -Cycle=22
ISaGRAF

Or in some OS such as OS-9 or VxWorks, you can directly set environment variables.
To do so use the following commands:

OS-9:
setenv ETCP_CYCLE 22
setenv ISARSI_CYCLETIME 22

Then launch the CMG (ISaGRAF)

VxWorks:
putenv ETCP_CYCLE=22
putenv ISARSI_CYCLETIME=22

Then launch the CMG (ISaGRAF)
