yyh2 Posted April 28, 2023 Report Share Posted April 28, 2023 Hey, I tried to create more than 24 screens on samba 4.3 ,and was suprised it cannot be done ( it was stated in the spec, i missed that part). what about samba 7 ? vision series ? unistream ? same with subroutines, what is the limit ? (this one is not in the spec). Regards Yam Quote Link to comment Share on other sites More sharing options...
DanT Posted April 28, 2023 Report Share Posted April 28, 2023 Hi; SAMBA is a very stripped down version of a regular Vision ( V350, V430, V700) PLC with "severe " limits on usable memory. SAMBA is meant for small stand alone projects. Just a few differences ( for a full listing of the limits, refer to a SAMBA Spec Sheet ) SAMBA Vision( ex V350) MB 512 8192 MI 256 4096 ML 32 512 MF 24 64 HMI Screens 24 1024 micro SD Card NO YES I/O Expansion NO YES UniStream B3 Series has limits ( Check the Specs), but the B5 and B10 models have lots of space.

yyh2 Posted May 1, 2023 Author Report Share Posted May 1, 2023 Hey Dan, thanks for the answer, there seems to be a very big gap between samba and vision. I'll take it into account in the next project. what is a B3 series Unistream ? I can't find such model in the website. what about the subroutine limit? I like to split them for clarity, but if there is a close limit (lets say 35-40) I can combine them and only watch out for the memory space. also, do I get "punished" for multiple subroutines in terms of scan time, relative to the same program in a denser form ?

pascal Posted May 9, 2023 Report Share Posted May 9, 2023 hi, about your subroutine question I have a univison type uSP-104-B10 (B10 stands for type of CPU, is TOPmodel😁😁) and in one of my programs I have already 9 modules and more than 100 "subroutines" without significant scan time (+- 48ms) -> I do have a lot of communication (modbus, opc UA, MQTT,Rest API,ethernet/IP) and over 40 PID's The only thing to watch is the depth of calling subroutines -> max 8 levels ! 1 Quote Link to comment Share on other sites More sharing options...
DanT Posted May 9, 2023 Report Share Posted May 9, 2023 Hi; The UniStream B3 Models - 2 Only -- are in the UniStream PLC Section - Tech Documenmts USC-B3-R20 or T20. They do not have a Built in HMI, The HMI is Virtual -- VNC from Display or PC The B3 is a subset of the Full UniStream Series and has Limits, but still very functional for the right applications. The unit has 3 GB for programming, Spec sheet does not specify a limit to the Virtual HMI's, or subtroutines called from the main. ( The layered limit is subroutines calling subroutines.)

yyh2 Posted May 10, 2023 Author Report Share Posted May 10, 2023 currently im with 35 and it works. visilogic on Sm43-J-RA22. Quote Link to comment Share on other sites More sharing options...
HansCZ Posted May 20, 2023 Report Share Posted May 20, 2023 I can only add there is a limitation of 255 elements on the screen on Unistream (at least b7/b10), regardless it is active (button) or passive(line) element Quote Link to comment Share on other sites More sharing options...
yyh2 Posted May 20, 2023 Author Report Share Posted May 20, 2023 on each and every screen ? if so, seems like more than enough. Quote Link to comment Share on other sites More sharing options...
DanT Posted May 23, 2023 Report Share Posted May 23, 2023 Hi; On UniStream, There is a method to change the maximum number of elements available on a HMI Screen. Contact Unitronics Support for the way to do it. DanT 1 Quote Link to comment Share on other sites More sharing options...
