Hi folk, I'm newbie in Siemens, What is the range for 0 to 10V output (0 - 150,000) ??? When I try to control a drive (0-10V) for a 460V motor, I think I set it 0 to 150,000 as Drive read 0-460V but I forget to use Meter to measure how much voltage from Analog output Card ! So I dont know is it right ?? I using the same Function Block for all of the drive, but when I test it, 1 drive work fine, other 2 drive cannot go over than 9400~ 4 Voltage (read from drive) What did I do wrong ??? While there is another ANalog output card, I think if I go over 10,000 it flashing red light !! Anybody have any idea ??

hi folks, I have a Sinamics G120C & BOP-2 Anybody experience with this before, help me in configuration setup for 2 wire control with 4-20ma speed signal from Plc thanks

Hi everyone, I have a dumb question here: 1) I have 2 CPU S7-1200 & 1 TP1200 & Switch: (connect via EN/IE) I'm going to program these 2 CPUs, For example if 1st CPU return an A results, is that possible 2nd CPU use A resuls as its own condition ??? So if YES, just leave results A as an GLOBAL DATA of 1st CPU then 2nd CPU can access it anytime in anycondition ??? or I have to do something ?? 2) Anybody know where I can set the Autosave time for auto backup ??? I've lost my work when I cannot save my work on Network drive and TIA just close the programm without saving anyof my work ! And I found a backup in my file but it was yesterday >_< Thanks

Hi everyone, I'm new to Siemens so that I need a sample code, I'm using Portal TIA integrated, so I cannot open S7p file, only can open hmi file or *.ap file ! (and dont know why while I did install Step7 basic) Thanks

I mean a project with all of buttons (switch, radio button, etc), change screen, language, ... connect with PLC code But, I guest I have to figure it out by myself, Thank you anyway Nelliyan

HI folks, I'm newbie and I'm trying to build my first simple panel with an AB 700 FSH Timming (120V input AC) & AB 700HTL1U1 terminal Block Relay (120V DC input, 120V output DC) & a DC drive with a Motor and a switch ^_^! I got trouble when I wired everything up, start the switch and the Terminal Block Relay light on ... but flashing and make noise ! I double check the wiring diagrams and still don't understand why the Terminal Block Relay flashing and make noise !! I think I used AWG#14 for everything (because that the only wire I got) But I don't think it's make problem right ??? OR ... something else I cannot figure out Plz help Thanks folks !

Hi folks, I am now encounter the problem that I never meet before, how can I control 6 VFDs which is connected (series jump) and all connected to a mini DIN AB 1763-NC01 ???? I usually work with Analog so I know the Address for Output control, however, in this case, how can I give them address and use it to control those VFDs ??? (Micrologix 1400) Thank for helping

Yes, all the Powerflex drives are connected serial by RJ45 and then to the NC01 card, this is a working Control Panel, and there is no program yet, so I wonder how come I will control them ?? how to assign them an address to give them an output control and speed control !? Thank you all guys

Hi Folks, I graduated as a ME, some how start my job as a Field Technician where I learned experience about reading electrical schematics and use the volt-meter (basic), PLC programs / RSView /C-more ! That all I learned from the part time job I have. I want to know what should I learn or prepare for myself to get a better job in the field related to PLC !!?? I don't know how to create a pannel, such thing like wire stuff. Again, I graduate as a ME not an EE, everything relate to electrical, I dont know or I know a little bit by experience ! What kind of job I can got with my little experience ???? what should I learn more ?? or just try to get a job where I can learn more about wire stuff (to know how to create a small control panel ????) Thanks

sigh ! There is no help

It's my I/O Configuration ! I checked and it work ! Thanks guy for helping me !

Micrologix1400, 1762OW8 exp, 1762OF4 exp Major Error S:6=287h "I/O configuration mismatch, check module 2. The expansion I/O configuration in the user program did not match the actual configuration, or specified a module that was not found, or the data size for the module was greater than what the module is capable of holding." I can download my code, go online, but cannot run because of this Fault error ? What did I do wrong ? Thanks

I checked the cables were fine, nothing wrong ! connection now is to connect 1762-OF4 to 1762-OW8 , 1762-OW8 to Micrologix !! or have to re-wire them to 1762-OW8 to 1762-OF4, then 1762-OF4 to Micrologix ???
