Note: With the use of remote contacts the signal sources* are taken over from
the control word 410. Signals at the hardware contacts (terminals) are not
evaluated by the standard operation modes (e.g. 71 for S2IND).
For the evaluation of terminal signals special operation modes are avail-
able. They are denoted with the additional term “(Hardware)” and num-
bered from 526 to 546.
Exception: The controller release via the hardware contacts STOA (termi-
nal X210A.3) and STOB (terminal X210B.2) must be set and Bit 0
“S1IND”
of the
controlword
must be set.
It is not possible to release the controller only via software.
Signal sources are:
- S1IND ... S6IND,
- MFI1D,
- EM-S1IND ... EM-S3IND
