1.5.3.2 Assignment and direction of effect of the digital inputs

see fig. 1-16, page 37
The control signals CB, He ...+yBLII, -yBLII are assigned by the structure switches S24 to S38
and S219 to S228 to the digital inputs BE1 to BE14 or the status Lo. In the assignment of CB
(S24), CBII (S219), PI (S30), PII (S31), wSLI (S225) and wSLII (S226) the High status
(S** = --1) is also possible. The control signals can be negated optionally by the structure
switches S39 to S46 and S229 to S230.
The digital inputs BE1 to BE4 of the standard controller can be extended with the option
modules 6DR2801-8C, 6DR2801-8E, 6DR2802-8B in slot 5 and in slot 6.
When using option modules in slots 5 and 6 the structure switches S22 and S23 must be set
according to the assembly, otherwise it will lead to error messages (see chapter 1.4.3, page
20). All digital inputs can be read by the SES.
1.5.3.3 Linking the digital inputs BE1 bis BE14 to the control signals via the
SES
(S47 to S49, S101)
see fig. 1-17, page 38
The control signals CB and N may be available optionally as static signals or as a pulse (key
operation on consoles) at the digital inputs. The setting is made by S47 for CB and S48 for N.
On selecting the pulse input, every positive edge flips the flip-flop. In the following descriptions
the output status of the flip--flop is assumed as CB or N.
All control signals except  Δw and  Δy can also be preset by the SES at S101 = 2, 3, 4, 5
and OR linked with the appropriate control signals through the digital inputs. The incremental
adjustment of w or y by the SES is not advisable on account of the bus run times. Since the top
operation hierarchy in a computer link should be with the autarcic single controller, the control
signals can be switched off by the SES by rounding with RC = Int∧CB via the Internal/External
key (2) of the controller or via CB
Fail line).
In addition the internal flip-flop can be activated at S101 = 2 to 5 parallel to pressing the keys
via Int .
ES
The CB signal is formed at S101 = 2, 4 as an OR function of CB
CB via a digital input so that operation can take place optionally with one signal.
BE
At S101 = 3, 5 the OR function is replaced by an AND function so that the CB set by the SES
can be reset via a central Computer Fail line.
The function RC = Int∧CB (computer operation) also controls the command variable switching
in all controller types, i.e. also in SPC-mode or manipulated variable switching in DDC mode
(see chapter 1.5.4, page 40). The two controller types S1 = 10/11 operate without command
variable switching. The Internal key and the control signal CB are available with the link RC =
Int∨CB for locking operation through the serial interface (e. g. when coupling to control sys-
tems).
