Re: Accessing EKM Meter with PLC using Modbus on RS485?

Yes, that helps very much, thank you. Since I would also see the request coming from the other device, so I would know what data was coming back... I just need to act like a slave device and when I see a request for the target device, I just read what the real target device is sending. There must be...

Re: Questions for a new installation

I'm really impressed with the quick and detailed responses here on this forum, thank you for the information! I'm feeling quite confident that one way or another I will be able to get your system to work. I'm very happy to hear that there are no ongoing fees for data access... I have walked away fro...

Re: Questions for a new installation

Yes, the EKM Push gateway connects to our distributed server cluster. Are there any fees associated with having an account on this server system? If you want to store meter data on a local server, I would run the EKM Dash on your server and connect to the meter via a USB converter or potentially an...

Re: Idea - Omnimeter to activate Shunt Trip breaker - Brownout protection

I think the best and most reliable solution is to accomplish this with as little hardware as possible, and with as little communications as possible... especially given that for my area where we get hurricanes, the time when you would expect to need it.. like during a tropical storm, internet may be...

Re: Accessing EKM Meter with PLC using Modbus on RS485?

I have two different installations I'm working on, one does have internet, the other does not, so I may end up with an ekm push, or perhaps the iserial or usb device... I don't think which other device is actually reading the meters really matters, because requests transmitted and data received by t...

Idea - Omnimeter to activate Shunt Trip breaker - Brownout protection

I thought I would post my idea for your Omnimeter, This is more of a feature suggestion than anything else, but if anyone has a suggestion on how to accomplish this, that would be great as well. It seems it won't do what I want directly, but I thought I would post it because I think it would add mor...

Re: Accessing EKM Meter with PLC using Modbus on RS485?

It seems that trying to communicate with the meters over RS485 directly may not be the best solution. My PLC is already controlling a lot of other devices with modbus, so I think that if I wanted to do something else with it, I would have to stop modbus, do the other thing, then start it again.. Als...

Re: Questions for a new installation

Maximum Length of the Pulse Output wire from the water meter to the Omnimeter Pulse v.4: We recommend up 200 feet for the Pulse Output wire. We have had customers who have successfully gone much longer. If you do go further than 200 feet, I would probably use shielded twisted pair wire. I have abou...

Accessing EKM Meter with PLC using Modbus on RS485?

Can I access the registers in an EKM meter with a PLC using MODBUS with the RS485 port? I would like to both read the registers of the meter, and control the outputs over RS485. I have a PLC already communicating and controlling other MODBUS devices, so I'm wondering if I can read and write to your ...

Questions for a new installation

Hello, I am trying to plan out a new installation using 3 of your Omnimeter Pulse UL v.4 meters and a water meter. I have some technical questions about your products. The first question I have is about wire lengths, how far can the CTs be from the Omnimeter? Can I extend the leads beyond 6 feet? If...
