Subject: Re: concat multiple waveform records
Your acalcout record has typos.
INAA:CA_LINK SST_EFPS_THYR:CURR_WAVE0 NPP NMS
INBB:CA_LINK SST_EFPS_THYR:CURR_WAVE1 NPP NMS
The prefix starts with SST_. But your caget has this: SSST_EFPS_THYR:CURR_WAVE0
Your calcout record links are missing the initial "S", i.e. SST vs SSST.
That is probably why they are CA_LINKS, they are not found in the IOC.
I have tried aCalcout record to concate two arrays as per below configuration. I am not getting concated values in the acalcout record.

Hi Jignesh,
I haven’t used it myself, but it looks like the aynApps aCalcout record type should be able to do this, using the CAT operator, although it might not be the most efficient way. The other approach I would look at would be to write a subroutine for the aSub record type to combine your input array values into an output array — this requires you to be able to write C code.
Hope this helps, please reply to tech-talk with any follow-up questions you have.

Hi,
I have requirement to concat multiple waveform records received from Modbus device to single waveform.
Please suggest aConcat or joinArray is suitable for this, though I have never used it.
Please guide.
Thanks and best regards,
