Ethernet & Sequencer Programming SM15K

6.5 Sequence control by user inputs (optional)
When a new sequence is created (by prog:sel:name), an assignment can be added to the sequence name
to give the sequence extra parameters.
Once sequences are uploaded, it is possible to start / stop them by user inputs. This gives the opportunity
to control the sequencer without the need of a computer. Even the network connection can be removed. To
do so it is necessary to insert 1 or multiple Digital I/O Interfaces (see section 5.11). The power supply will
be able to work stand-alone in the field and control up to 25
1
different complex processes (one at a time).
There are some rules that must be followed:
1) To start a sequence, the related user input must change from "0" to "1".
2) To stop / finish a sequence, the related user input must change from "1" to "0".
3) To start another sequence, the other assigned user inputs must be "0".
The assignment of a user input to a sequence must be included within the sequence name. A sequence
name can be max 16 characters long. The last four characters can be used for assignment. First the
separator "+", followed by A,B,...,G or H (the name of a user input) and the slot number.
Character 3 and 4 allow to set some options:
3th: S (Stop) ; When the assigned user input changes from "1" to "0", the sequence will
stop immediately.
F (Finish) ; When the assigned user input changes from "1" to "0", the sequence
continues until the command END is executed.
4th: R (Restore); When the sequence stops, the SM15K restores the voltage and current
settings that where valid before the sequence started.
H (Hold) ; When the sequence stops, the actual voltage and current settings remain
the same.
Assignment examples:
<seq name>+A1SR ; The sequence starts when user input A (slot 1) becomes "1", it stops
immediately when user input A (slot 1)becomes "0" and the voltage and
current settings are restored.
<seq name>+D3FH : The sequence starts when user input D (slot 3) becomes "1".
When D (Input slot 3)becomes "0", it finishes the steps until END is
executed and holds the actual setting for voltage and current.
Any combination of the user inputs and the options can be made. It is required to set every
character of the assignment. Refer to section 6.3 to find the command to program the sequence
name. The length of the sequence name + the assignment has a maximum of 16 characters.
1) When 4 Digital I/O Interfaces are inserted.
