SimonK Posted March 31, 2022 Report Share Posted March 31, 2022 Hello, I bought Samba SM70-J-T38 which has HSO (step control), these outputs can be control on other PLCs lik V350 by PTO function. How can I obtain the same PTO function for my PLC? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
John_R Posted March 31, 2022 Report Share Posted March 31, 2022 Hmmm.... I don't have an answer to your question, but this raises a question from me... What version of Vision are you using? I have .65 & .94 installed and neither shows a "T38" I/O option for a Samba SM70 -J Quote Link to comment Share on other sites More sharing options...

MVP 2021 kratmel Posted March 31, 2022 MVP 2021 Report Share Posted March 31, 2022 I think - it is not possible to run PTO on this Samba PLC. You must ask support@unitronics.com for information. @Flex727 If this I/O option not present in 9.8.95 and file SM70-J-T38.ini not present in folder .......Unitronics VisiLogic_C\Data\HW Cfg in this new Visilogic version - SM70-J-T38 - OEM version of Samba PLC. Needed Visilogic config files for this OEM provided by support. I ask for SM43-J-TRA22-TV OEM PLC config files - support provided needed config and send instruction how to activate this PLC in Visilogic I/O.

MVP 2021 kratmel Posted April 1, 2022 MVP 2021 Report Share Posted April 1, 2022 PTO is possible for this I/O combination V350/ V130: Although you can implement stepper control in this way, V350/130 models such as the V130/V350-TR34, TRA22, TR20, TR6 and EXF-RC15 offer high-speed outputs that support PTO Functions T38 is not present in PTO Visilogic Help and no Samba present.

SimonK Posted April 1, 2022 Author Report Share Posted April 1, 2022 Thanks a lot for your answers. I would like too have an examolebto control the HSO without PTO. Is there some example for the task? Quote Link to comment Share on other sites More sharing options...
DanT Posted April 4, 2022 Report Share Posted April 4, 2022 Hi ; First you need a reliable time base. The only reliable time base will be the 100ms pulse so use it to turn a MB on and off every 100ms = 5 Hz Scan time is not reliable as it can vary from place processor activity, it may be faster, but not steady. You could look at the Interrupt routines -- 1.25mS and 2.5mS they have to be very short to be effective and not slow down the PLC processing. There are programs in Example to show how to use them. You will have to test and experiment. Move over to a Vision PLC that has the PTO Outputs already available. DanT Quote Link to comment Share on other sites More sharing options...
