  1. How to adjust the resolution of a timer on FB

    The time base is dependant on the timer number,  
  2. Corrupt program?? GX works2

    I find that this issue occurs if the USB stick is removed without first using Windows to shutdown the stick and wait for it to tell you it is safe to remove it, if you just pull it out after use then when plugged back in any PC or laptop, Windows reports there is an error with the stick and requests you 'fix it', Just ignore the message and carry on, It's just Windows nanny operating system kicking in Steve
  3. MOV H400 K4M60? Hexadecimal

    The K4 in the instruction represents 4 nybbles (group of 4 bits = nybble) therefore K4 signifys 16 bits The instruction is moving Hex 10 into M60 to M75, (K4M60), as the binary pattern of hex 10 is 0000000000010000 then M64 becomes true.

    It would appear that it depends which polarity the COM is connected to as to wether the inputs source or sink examine the diagrams closely with regards to the COM terminals.
  6. Pacdrive C400

    Thanks for that, I have dug deeper and found that the current software is probably Schneiders EcoStruxure Machine Expert V2.0 LogicBuilder. There is a 42 day free trial (Rockwell please note), so have downloaded and installed (2.5hrs) to check out. Steve
  7. Hi all, Just been given a task of modifiying the program in a Pacdrive C400 controller, (a new one on me). According to Google, the original manufacturer was a German Company ELAU, who have subsequently been obtained by Schneider. It would appear the programming software was EPAS-4, but there is no reference to this on the Schneider website and I can't find any definative answer to the programming package I need to obtain to be able to view/modify the program. Any info would be appreciated. Steve
  8.   This should help, Schnieder info

    Welcome, As a start I would check out the  Analogue Manual Section B there is a mass of info along with a practical programming example to get your teeth into.   Steve
  10. Check this website for info, appears to be just a USB printer setup.
  11. Timer IC

    you will have to explain further what you mean by the term 'IC' what do you refer to when you say IC
  12. Timer IC

    assuming you mean a timer intergrated circuit a simple well documented unit would be a 555 timer ic, for use with a minimal number of discrete components
  13. You can choose whether  D200 to D511 are latched or not, the 'fixed latched' are just as stated fixed.  
  14. Download the manual no. JY997D16601 and look at the 'devices in detail' it explains how to configure 'D' registers and which ones are battery backed etc. Steve
  15. Mitsubishi FX2N PLC to GOT 1000 HMI

    I believe that the GOT1000 serial port you refer to may actually be a rs422 to rs232 converter plugged into the HMI, if you look carefully I think you'll find it's removable (well it is on my GOT1504).
