thank you Jeremy. Great clear instructions. most appreciated

Hi Guys I have a ultarsonic level sensor set up in mango with MODBUS the dat point is set up well and is reading fine. But I cannot seem to find how to create an email alert, say for example if the water level exceeded 4m, how to get an email sent to somebody? similarly if it went under a level.?

thanks in advance

Thanks ,v8dave and Phil for your responses. Here is the document. Also to tell you about the device it is fully web accessible and has setup pages including a socket setting where you can configure
Network Parameters setting(TCPB),
Port ID
Server address
TCB Time out setting

Hi there, I have a WiFi/Ethernet relay board (8 channels output) 3 channel input. The input is monitoring a door status using a reed switch. (open or closed status) how can I in mango have a data point for monitoring the open closed status. the relay board ships with a GPIO Controller protocol manual but is is over my head. I can post it here if it helps,

Sorry I meant to say I change the data source to MODBUS IP because I could not get the COM to to work

Here is an update. I now can read the registers of both devices. the second device which had Modbsus ASCII as default I had to change to RTU. Now I need to figure out how to set up the data points

here is the RS485 Modbus guide for the Flow m0_1466480777062_FlowRS485.doc

Thanks Joel & Phil. yes I see your point about the non matching slave/com port. I should have matched it to avoid confusion but that is actually how they are setup/ Slave 1 on Com2 and slave2 on COM1. Yes I am on Windows. I will attempt to run your suggested tests and report back

any recommendations
for this type of software?

Thanks for your suggestion Joel but still getting the no response error

Hi Woody, thank you for taking the time to reply. the modbus test software is generic not supplied with the device. i checked the comm port settings and they match. So I wonder if my serial to ethernet converters servers for some reason are not playing nice with Mango. Because they work with the test software.
Basically each modbus device is connector to a serial to ethernet converter see drawing (thetop part is description bottom part just icons of the same) and a virtual comm port is created for each device.

They also support IP so I tried MODBUS IP and get the same no response error. but if I change the ip port from the real one to a random ip port I get a timeout error. Which makes me think the connection settings are right and the request to the slave is getting through but just not getting a response from the devi0_1466476518946_ConnectionDrawingt.pdf ce.

Any thoughts?

Hi there I am hoping someone can assist here
I am trying to add 2 MODBUS data sources but am getting a “No response from slave error” for each device. (however when I test in a Modbus test programme I am having no issue and am able to send commands and receive responses with no delay etc) I have double checked the settings on the devices match the Mango serial properties for each data source
1)The First device is a Level Meter connected on virtual com port via RS485 Modbus RTU (connected on a COM2)
It is not detected on the Modbus Node Scan and generates a ” error
2) The second Device is a Flow meter connected on a virtual COM port via RS485 Modbus on (COM1)
It is not detected on the Modbus Node Scan and generates a “no response from Slave 2” error

Are there settings elsewhere I need to configure in Mango?
