  1. Hello everyone I have a question about temperature of plc. I am using V700 and in tech spec i see the working temperature 0 - 50 degrees of celsium and i can check it by turning on SB14 and the value will be shown in SI14. So here is the question - does it have build-in protection from overheat or undercooling or do i have to organize it by myself? Did not find the answer here, so decided to start new topic. I don't think that i need it for my current system, but still getting some extra information about it might be viable. Sorry for bad english, it is not my native language
  2. Thanks for reply. I was not involved in choosing platform, my directors were, but V700 seems fine to handle our task. Probably in future they'll make a decision to change to UniStream. I haven't download UniLogic yet, because i'm not familiar with ladder logic at all and haven't got almost any experience in it, but i'll probably download it later and check this program product also just for myself.

  3. Hello everyone, i found some similar topics about passwords but they did not help me, so i decided to start this one. What i'm trying to do is make multiple access levels. So i need 17 passwords, first i was trying to make legal entries as vector of DW operands, but it seems that it works only for one operand which sits in DW20. Here is screenshot. (Yes, i linked MB13 to legal entry, not on this screenshot, but in project) After that i was trying to link it to data table, but it did not work for me In data tables there are no IDs, just passwords, so there is only one column. So, basically, my goal is to press on Variable: Password button, enter some numbers and i was trying to get 2 results: 1. It will find it in data table, get the row number and i will compare it with one of my constants to get the proper access level or other option, or 2. Input password will compare the vector of password DW20-DW36 with some DW20/21/22... to get proper access level or other option. Sorry, that is my first project and i think that is kinda similar question, but still got some trouble with it. If you need, i can link my project, but the problem is that it's all in russian language, so you probably won't understand anything in it and also i'm almost non-stop changing some stuff trying to figure out passwords logic. And sorry for bad english, it's not my native language. Thank for help Well, somehow i made it work with Variable: Numeric, loading some numeric value, comparing it with data table value, getting row number and then comparing it with some constant But anyway, for my future projects - is that possible to make similar thing with Variable: Password?
