6. The processor module changes over and indicates P1 (working mode OPERATION).
The system is now started and ready for operation.
Perform the final stages, including start of application program execution, successively.
WARNING
When the application program is started, the process being controlled is
influenced.
Significant engineering tool commands to use are:
1. DIsable Build Mode, DIBM PCx
2. DeBLock, DBL.
Verification
Make functional tests, including process functions, applicable.
2.6.7 Power-up Ahead of Program Loading
1. Set the mode selector on Processor Module PM511 in 3 (CLEAR) position.
Repeat for an eventually redundant processor module.
2. Switch on the circuit breaker S1 on the power switch unit(s) in any order.
(If this circuit breaker has been used to switch off the power supply to the system.)
Several power switch and distribution units can exist in the controller cabinet or in
adjacent I/O cabinets.
3. Check for the following positive indications of a successful power-up:
– Distribution Unit SX554 green LED LIVE (24 V)
– Regulator SR511 green LED 5 V
– Backup Power Supply SB511 (or 510) green LED RUN
– S100 I/O Bus Extenders DSBC 174 or DSBC 176 green LEDs RUN
and DC OK
– Processor Module PM511 green LED RUN
display ind. P2
(Indicating working mode CONFIGURATION.)
– Redundant Processor Module PM511 (BACKUP) green LED RUN
display ind. b2...b1
(The backup unit starts in working mode b2, UPGRADING. After a while (
<
90s)
there is a transition to b1, STANDBY).
If a redundant processor module is available, and if both modules’ start mode
selectors are set in 3 (CLEAR) position, then the left processor module will be
PRIMARY while the right processor module will be BACKUP.
Chapter 4, Runtime Operation explains alternative ways of starting.
See Figure 2-25.
