  1. I am looking for a software that will allow me to display some data from my ABR driver. I am want it display it in a web page. This info would be mainly power monitoring info for the big bosses to see when they want. Has any one done this or have any ideas. I am using an HMI package but to get additional keys for one screen would cost too much. thanks scott
  2. Channel 0 is modbus RTU Master while Channel 1 is Ethernet.
  3. Ken I switched A&B around and now i get a message of DF1 FD- local communications has been lost. Not sure if i improved the issue or made it worse. thanks scott
  4. I am hard wired from the PLC 485 adapter to the drive. I am getting a time out error. msg_block.doc
  5. i am trying to get a ML1100 to talk with a ACS350 ABB drive. I'm not sure what I am doing. I have it wired up per the instructions from Rockwell's site. Is there a way to test if I'm wire correctly? Does anyone have an example of a program that would pull a word or two from the drive? thanks in advance for the assist. scott
  6. I need to use a SCP statement in a ML1200 unit. Is the scaling 3277 to 16383 like in the SLC500 processors? thanks
  7. RF to PLC

    We are using Freewave Radio system that is a broad spectrum freq setup. This is using the DF1 comm port for transmitting the data back to the master radio. Currently have 17 station with a scan time of about 18 seconds or so.
  8. You could look at GE Faunc iFix. I did our waste water plant from HMI system in house. Very easy to work with. I also looked at Wonderware and picked iFix due to cost.
  9. Pump system

    I may just not be seeing the forest among the trees. I will have to look over the old Symax Square D program again. Thanks for the assist.
  10. I have a 3 pump system that i need to program. One pump needs to be running all the time. But if the system pressure drops below a setpoint a 2nd pump will come on. If we are still below pressure the 3rd pump will come on also. Note there are time delay between pump on triggers. If 3 pumps are running and our flow is below a given value we will turn off the 1st pump. Then when we are running 2 pumps and our flow is below a given value we will turn off the 2nd pump. Kind of a first on First off setup. Can this be done in straight ladder logic or do i need to use a sequencer or FIFO setup? My contactor does not want to use the sequencer or FIFO at all and I have to convince them that straight ladder logic will not be the solution. Any ideas? If so is there an example i can look at for this?
