RKC PF900 SpecView support for Patterns and Segments.
The SpecView support for the RKC PF900 is split into two SpecView ‘Instruments’:
The Controller part of the PF900 (Instrument called ‘RKC PF900 Controller’) and:
One for Pattern 1, Segments 1-64 (called ‘RKC PF900 Pattern 1’).
The Pattern 1 instrument allows the user to easily create and modify pattern 1 in the controller from a SpecView recipe screen – all the components of the segments are on screen at one time, and all can be read simultaneously.
Suppose the instrument is at Modbus Slave address 5. Create a ‘PF900 Controller’ at address 5,0 to access the controller parts and also, if needed, create a ‘PF900 pattern 1’ at exactly the same address.
Using the ‘PF900 Pattern 1’ Instrument:
In addition to all the segment data, there are also the following extra parameters at the beginning of the list:
Programming Other Patterns or other segments not included above.
This is done using what we call ‘keyhole surgery’. In the controller instrument, at the end, there are the components of a single segment, as well as Pattern and Segment number selection parameters. There are also the various Pattern controls as well as the segment controls.
To program a pattern, proceed as follows:
Set the ‘Pattern Number Select’ to the desired pattern number.
Fill in any data in the ‘Pat:’ parameters that are to do with the Pattern.
Set the ‘Segment Number Select’ to each segment in turn. When this parameter is set, then the ‘Seg:’ parameters allow the reading and writing of that segment’s data. Once the segment has been programmed, move to the next segment number by changing ‘Segment Number Select’ and setting the data etc
Using this mechanism, it is possible to program up to 99 segments in a pattern, or up to 99 patterns of a smaller number of segments.
To setup a recipe screen using this keyhole surgery, please call SpecView for help. It is possible, but requires more work.
