Technical data

RS 80 Address: EA50H (high and low):
This contains additional information to define the cause of the error
when bit 5 is set in RS 8 by the system or when control bit FE 5 is
marked in the ISTACK output.
Identifier in RS 80 Cause of error
2460H
Ready signal continuously active on the S5
bus
RS 130 Address EA82 (low):
The system data RS 130 indicates the following statuses of the
program processing level "closed loop control".
Bit no. 0 = 0 : program processing level "closed loop control"
activated
Bit no. 0 = 1 : program processing level "closed loop control"
suppressed
Before you call a restart organization block (OB 20, 21 or 22) the
system program evaluates data block DB 2 (if it exists). Depending on
the result of the evaluation, RS 130 is set or reset by the system
program. Following this, the system program calls a restart OB.
If RS 130 (LOW) is reset, the closed loop controller is processed in
cyclic operation according to the controller list in DB 2.
