- HMI Model: cMT2108X2
- EasyBuilder Pro Version: V6.09.02.510
We have built several machines for a customer that has an ever increasing number of new part types. They have already reached the record number limits on the recipe, and necessitated creating a second recipe. The customer wants to be able to combine all of the parts into a single recipe table, and still have room to expand.
We have proposed using an SQL database and advanced model HMIs on their new machines, but their existing machines use cMT2108 HMIs and are not SQL capable- plus there is worry about the long-term feasibility of them being able maintain the SQL database on their production floor.
Is there any way to get a larger recipe table on the standard model HMIs? We are using the built-in Codesys core, so if something could be done on the PLC side that would also be worth looking into.
Also, a second question, has the number of recipe records been increased? When we built the first of these machines two years ago I know I was running into a wall when trying to add more than 2000 records to the recipe database. I just read in the recipe database manual V1.01 that the limit is 10,000 records.
Hi @jnorris,
A recipe that contains an appropriate column count with respect to the limitation on items (no more than 1,000) and word length (less than 2,000) can hold 10,000 records.
A 2,000 word limit applies to recipe items, as an example, if you wanted to have 25 columns, where each column is a 100 word string, the size of a single recipe would be 2500 words. This could cause project compilation to fail. However, if the recipe was simply 2 columns, a 10 word string and a 2 word float value, the project would compile without issue because it is less than the 2,000 word threshold.
If your customer would like a recipe table larger than 10,000 records, using a SQL database would be a good option.
