Hi Well,it's just two rungs code,1st rung has PRV,2nd-INI to zero it,...basicly i just wanted to test it before i replace some unknown encoder on one of our machines. Thanks.

Hi I connected Koyo incremental encoder to cpm1a i'm using PRV to read PV,for some reason it skips some counts,example-counts from 0to ~2500 and then "jumps" to ~4000,again counting from 4000 to ~6500 and "jumps" to ~9000. I would appreciate if somebody could explain me why it skips counts. Thanks.

Well,now it's S5,i am cosidering S7-300 or 1200 or Micrologix....wiring is not a big issue,i just want to see if wiring done by contractor more or less in range of home electrician's salary,if it is,so i'll have contractor do it,if not,i'm gonna see. Thanks.

I understand it's for programming,and wiring? Also,i believe if it's a long job the hourly cost can be reduced? Thanks.

Hi It's hard to be specific,that's why i asked what is the average cost for programming/wiring....more or less,...it's aprox 120 I/Os,10 analog. Thanks.

Hi We have some eqipment to modify....which includes new hardware(PLC),new program,wiring etc,we had a few guys came in to see the job....i would like to know what is the reasonable/average cost for these kind of jobs. Thanks.

Hi I have a machine running with MP 277,the program is on SD card,i want to back up it,is it enough just to copy the SD card using card reader and if i need then to paste it to another SD card? Thanks.

Thanks.

Hi 1.Are there FBs in micrologix family of AB?,i mean for example like FBs in S7,so i can wrigt the code only once to control several identical stations. 2.Is Micrologix software friendly? Thanks.

Thanks.

Hi I have TSX 57103 V5.0,old memory card disappiared and no way to get another the same one,it's obsolete ,the replacement TSXMFPP128K requires Firmware minimum V5.5,i've got V5.8,my question is what surprizes can i expect if i update the firmware....like program not compatable with newer Firmware...etc?

Hi aggattapauer I have a few questions to you: If i go PLC menu there i've got 3 options 1.Transfer program 2.Transfer Data 3.Back up..... To upload program from MC will it be enough just to choose Backup (will it upload both program & data?), or i should use options 1 & 2? Thanks Appreciate your help.

Hi The reason is we have 2 identical machines Memory Card from one of them disappeared.....:). let me please ask you a few questions: 1.Any PL7 software can connect to this CPU? 2.Are there alternatives to this quite expensive software,i mean we just need to upload/download program and eventualy monitor it,so it's not worth to pay ~$2000 for that,but if no alternatives we will buy it. 3.I'm not familiar with PL7,to upload from MC and download to CPU should i know some hidden things,or it's just straightforward ---->upload from,download to....? Thanks. Appreciate Your help.

Hi I have Modicon TSX P57203,program is stored in memory card,....for some reason we need to remove the memory card,but we need the machine running....what are my options? Is it possible to upload the program from the memory card and download it to CPU directly? Thanks

Hi Can i use optional rs-485 CM module for data exchange between two s7-1200s. Thanks
