Hi, Can the xG1W-2 read DS18B20 Temp sensors that are wired on a bus that is operated using Parasitic Power?
I am trying to use a Wellpro WP3066ADAM to read some one wire sensors over modbus, in Mervis 2.2 I have the modbus channel setup and group setup, configured one datapoint for Sensor 1 so far, but the value I am receiving is not even close to being right. Comes in with something like -3.567589e-18 and it changes when I place the sensor in my hand. I looked at the modbus tutorial but cannot get proper readings.
Can someone please take a look at this modbus command and let me know what I should be entering in the Modbus Datapoint Parameters section for each sensor?
The issue I am having is the variables. What is the proper way to migrate to a new version of ide? I downloaded the configuration from the PLC, exported and imported the .hw files and added the program. I'm still missing the variables, is it possible to export the variables or am I going to need to enter them all by hand?
I am having trouble getting my program to work with an updated Mervis IDE. I used version 2.0.5 on my old computer, and installed version 2.0.12 on my new computer. When I try to open my solution i get a popup that shows the following:
"Solution contains unknown module references. These references will be removed."
So when I click ok for the solution to be fixed it opens but when I try to build solution it fails and a long list of warnings shows up in the results.
Warning Snow 0 1 Changed UID of variable $base$.$sint_to_string$.$eno$.$3f-6b-16-b5-a9-12-be-83-ec-ba-5c-e7-55-b1-fa-ad$
I could use some help to get this straightened out, I would appreciate it
Ok, I am having an issue with the I2C, I cannot get the 8 channel 1-wire extender working properly and now I cannot get the 4 AO expansion board working either. So it leads me to believe I am having an address problem, what address do I enter in Mervis when I select on the board?
For instance, the first one, 0 0 0 40 64
I hooked up 8 channel 1-wire expander to the I2C, and messed around in Mervis trying to get it up an running without luck. Is there a document that describes how to set it up? If not, can you list out the steps on the forum that way others will be able to search and locate it.
