ABB SPAC 310 C - Conditional Direct Output Control

16
The Conditional Direct Output Control logic
controls the outputs OPEN, CLOSE and SIG-
NAL1…3. Outputs not used for controlling an
object or for signalling the activation of inputs
4…13 can be controlled by the Conditional
Direct Output Control function.
The outputs are activated on the basis of the
programmed logic and the status of input chan-
nels 1…3 and 4…13. The controlled output
remains active as long as the statuses of the
inputs which caused the operation do not change.
Fig. 11. Operation principle of Conditional
Direct Output Control.
The programming principles and the program
structure of the Conditional Direct Output
Control are the same as those of the interlocking
logic. The differences between these two logic
programs are;
- The codes of OPEN and CLOSE outputs
- The outputs SIGNAL1…3 can be controlled
by the Conditional Direct Output Control
program.
The output codes are:
Output code Definition
220 OPEN
221 CLOSE
22 SIGNAL 1
23 SIGNAL 2
24 SIGNAL 3
The Direct Output Control program is written
after the interlocking program by using the SPA
protocol commands M200…M300. These two
programs have a common END command.
Example 9: An interlocking logic was pro-
grammed in example 8. In this example a Con-
ditional Direct Output Control logic is added
for SIGNAL 3 output.
The SIGNAL 3 output will be activated when:
- The CB truck is in the isolated position and
input channel 4 is activated

ditional Direct Output Control logic for the
example number 9.
The described Conditional Direct Output Con-
trol logic is effectuated with the following com-
mands.
