  1. It's based on voltage differential signaling so an optocouple would kill it. You could try a quarter amp fuse. 
  2. It's on page 149 Note the text from page 150  
  3. Download vs Upload

    It reversed from how you'd use an ftp
  4. Allen Bradley 1746 specs frustration

    I'm just sitting here hoping no one is using an SLC in a new application.
  5. RSLogix 5000

    Did you reboot after the install?
  6. RSLogix Project Migrator

    I've had better results copying the rungs via copy and paste.
  7. You need a converter to go from TTL to rs485. There's a voltage difference that could potential cause damage to cheaper equipment. This is specifically made for what you're doing. uxcell 5V MAX485/RS485 Module TTL to RS-485
  8. Open The Door and switch the switch to Remote [REM]. PLC is most likely in run.
  9. It's not in the menu on the hmi, I had to use SoMove to find the value to change. Even then that was a Run CMD by Network. I think this is exactly why most VFD's are controlled in Hand or by PLC/DCS  
  10. High Pass / Low Pass Filter Knowledge

    I'd like to know the application. There are differences in how you would use those depending if it's radio, telecom, cablecom, dsl, or even docsis cable.  
  11. ML1400 AB_ETH_TCPIP DHCP MSG Help

    MSG command is for PLC to PLC not PLC to HMI
  12. Programming cable

    Just use which ever of these will fit between the usb to serial converter and the HMI.     Null Modem Adapter Male to Female  Null Modem Adapter Female to Female Null Modem Adapter Male to Male
  13. WeinTek to AB PLC Issues

    Did you create the missing Datatypes?
  14. Easy builder pro - PLC No response

    Generally it's either a firewall issue or on occasion I've had the simulator not close and had to manually terminate the application from task manager.
  15. Download problem for OP-320 A HMI

    Just use which ever of these will fit between the usb to serial converter and the HMI.     Null Modem Adapter Male to Female  Null Modem Adapter Female to Female Null Modem Adapter Male to Male
