IP 266 STEP 5 Programming
9.4.1 Cold S5-100U Restart
Before you can work with the IP 266 following a cold S5-100U restart, you must
wait for completion of the module's runup phase. You must program the waiting
time in OB 22, which executes after every "Power OFF/Power ON". The pro-
grammed waiting time must be at least 3 seconds.
