  1. Can I change the gateway online on a 1756-ENBT/A ? I want to have access to the PLC but the eng station is in a different network and for that I place a xp windows PC as a router to connect both LANs, but I need as well to change the gateway in all the PLC while they are in production. LAN A - [xp router] - LAN B where the xp router is my new gateway IP My questions are Can I do it without causing any interruption? Is there any risk or anybody had a crash experience while doing this kind of change? How should I change the RSlinx to browse in a different network where the PLC is (from A to B)?
  2. Host Link serial is a very old protocol, I could not find any gateway to do the job, Some Woodhead ($700) say they can do Ethernet Symac FIN host link, but not specifically serial simple host link. For me throwing an AB PLC with a modbus card and a serial card seems inexpensive and a quick solution. I taught maybe someone know a third party vendor or a AB PLC solution
  3. I would love to add a Modbus card to the Omron PLC but I can not be that invasive in that system because is not 100% our system. The Red Lion looks very powerful but I have not yet found a specific reference to Host Link I’ll keep checking Thanks for your help
  4. Hi!! I want to build a small stand alone system to interface from a C200H Omron PLC with a Host Link serial port to an ABB modbus system RS232. Do you know what Allen Bradley cards Do I need to get, I want to use a SLC500 or 5000 rack and CPU system? If there in not a Host Link card for Allen Bradley then I need to send simple ASCII strings to the Omron PLC using a standard serial 9600-7-E-2 and it will send back strings back with the information and a simple checksum added. Then I will need to put this data available in my 4000x modbus address on a Modbus card. Thanks in advance
  5. Is there any black box out there to convert Sysmac Omron Host Link to standard Modbus? thanks
  6. I am connecting to the serial port using the Multiway omron program and an/or an OPC program I found on the internet. The PLC is running as a counter, counts hours and events in a gas turbine, I want to bring the data to the DCS display so is not just in that box but available to all the personal in the plant. Seems I was able to read the 100 words in the hold registers but I could not found the numbers I am looking for in HEX or DEC. With the Midway I am able to read the first 2000 addresses and then it gives me an abort error. According the manual I should be able to read around 6000 bytes? . I have the password but nowhere put it in the Multiway.
