In this blog, I will discuss the steps involved in getting the Netbiter to record and display values coming out of the ComAp Generator Panel, so that one can do remote monitoring and control of the generator. The Netbiter Model used in this case is the EC220 and the panel used is the InteliLite AMF 26 P. The steps followed here can be applied to any MODBUS device due to the generic nature of the Netbiter. S tep 1 - Physical Connection Check that the Control Panel has a communication module attached to the back of it. You will need to establish the medium (RS458/RS232) and the protocol spoken (MODBUS RTU/ASCII) - all of this information will come from the user manual of the generator. Finally confirm the communication settings (baud rate, parity, stop bits, etc) - these can sometimes be changed so check what they are on the actual panel. In this case, we have the following settings: MOUBUS RTU over RS232 (you'll need an external converter to convert the RS232 to RS

It's here! Transparent PROFIBUS PA link for 12 Mbps with COMbricks! PROCENTEC’s transparent PROFIBUS PA link/coupler enables seamless high speed integration to PROFIBUS PA. It powers the attached devices and fully emulates all PA devices as DP devices on the PROFIBUS DP side. It does not require adjusted busparameters and is therefore suitable for all DCS and PLC systems, even ones running on 12 Mbps. The combined internal ProfiTrace and oscilloscope make this product extremely useful for remote maintenance over Ethernet. Jitter, noise, DC current, DC voltage, bar graph and oscilloscope, it is all there and easy to access. The free CommDTM allows access for asset management tools over Ethernet. The PA link is a module that fits in the COMbricks system able to carry 9 PA links and a RS 485 or Fiber Optic module. It can also be a customized mix of PA modules with other communication modules. The PA link can provide 500 mA segment current on a customizable bus voltage.
