Thanks for answering, actually my options are limited in terms of budget and technology available, I wonder if I could work with a Bematech printer LR2000 and a SRM6000 Frequency Hopping Spread Spectrum Radio Modem...

I have a level measurement system by fmcw radar (Rosemount tankradar), for a filling-emptying process, of very large water chambers.
Very sporadically, the radar is momentarily lost and measures 4 to 7 feet below the actual level, only when filling the water chamber. Sometimes the measurement freeze in the middle of the filling process.
Due to the criticality of the process, this behavior is dangerous, as it can cause flooding inside the plant
This behavior is very sporadically so we are baffled about the root cause of this problem.

Hello,
I have a fuel level reading system in a 2000 gallon diesel tank. the system has a slc 5 05 of rockwell. I need to connect the system to a printer located in an office 300 meters away from the tank. can someone give me lights about the type of printer I need and what communication technology to use, preferably wireless.
Thanks.
Devicenet nodes falls, 1747sdn failed
in Allen Bradley / Rockwell Automation

I connected to the network through 1784 u2dn to be able to configure from RSnetworks, but the program only saw the Flex io, not the 1747sdn module. According to the manual, a resistance of 60 ohms must be measured between the blue and white wire, when measuring with the instrument it gave me 120 ohms, which seems to indicate that a resistance was missing at one of the ends, so I placed a resistance of 120 ohms in the end of the devicenet module, to get the 60 recommended measure.
The module was kept with an error code 91 So I decided to change it for another card, when changing the card the module indicator LED was no longer in red but it was impossible for me to communicate with the card through Rsnetworx. The other two nodes of the devicenet network had to be disconnected so that I could see the module in the RS networks. I loaded the configuration of a similar network previously saved in the computer, but when connecting the other nodes of the network to load the scan list the network fell and I could not continue with the configuration of the module and now i can not see any node from Rsnetworx.
