Posted 26 Oct 2022 Hi guys, I have been thinking about wether can increase the numbers of produced and consumed tags, between my plc-s. Currently I have two plc it already have produced and consumed tags, but unfortunatelly soon we are running out of free tags. I read the manual and it said I can make 125 dint tags, currently we have only an array with 10 element. If I make a new one and I kinda copy it, with different names, will it be work ? Or do I have to set something else ? Can I ruin the communication with the two plcs ? THanks ahead. Share this post Link to post Share on other sites
Posted 26 Oct 2022 Yes, you can have multiple producer/consumer tags. The limit is the number of connection resources in the processors, not the number of tags or size of the tags. Each producer/consumer tag can be up to 500 bytes (DINTs are four bytes, so 125 DINTs). 1 person likes this Share this post Link to post Share on other sites
Posted 26 Oct 2022 Thank you so much your answer. In this case do I have to download the plc program again ? Or I only have to create the tags in both PLC and done ? Thanks ahead. Share this post Link to post Share on other sites
Posted 26 Oct 2022 I'm pretty sure you can only set up producer/consumer tags offline. So yes, you will need to download to both processors. I highly recommend that you create your Producer/Consumer tags as simple arrays of DINTs, and then use the CPS instruction to move data to/from other data types (UDTs, whatever). There are many techniques to rework tags and types that aren't producer/consumer while still running. There's no need to make the P/C tags a structured type.
