The 1746-NIO4V is an analog input/output module capable of reading -20mA to +20mA or -10v DC to +10v DC depending on the dip switch settings. The card is also capable of sending out a signal with a voltage range of -10v DC to +10v DC A typical problem we will have with this module is…
What is Integrated Architecture Builder (IAB)? Integrated Architecture Builder (IAB) is a graphical software sales tool for configuring Logix-based automation systems.It allows to validate the performance of the network and includes a list of materials with cost, graphics and customized reports. IAB can be used to configure Logix-based automation systems (which include the PlantPAx process…
4-20mA Loop basics Every 4-20mA current loop consists of the same basic components: A power source, a transmitter (flow meter, level sensor, etc.) and one or more passive devices (PLC input, analog meter, etc.) wired in series as part of the loop. The power supply (typically 24VDC) provides the power for the loop, the transmitter…
What is an EDS File? Electronic Data Sheet (EDS) files are text files with *.eds extension that detail the parameters and configuration necessary for a particular device or device interface. EDS files are used by communication-based software such as RSLinx or RSNetworx to identify the device. The EDS file is provided by the vendor/manufacturer of…
The Allen-Bradley PLC-5 has four LEDs that display the operational condition of the processor. They are BATT, PROC, FORCE and COMM. There are four (4) classes of PLC-5 processors, referred to by the name in the following table. The Classic PLC has a slightly different layout for the status LEDs. Refer to the proper image…
In its earliest stage, space travel was a largely mechanical endeavor. It initially hinged on the use of rocket propulsion to move machines, including early satellites such as Sputnik and Explorer 1, into orbit around the Earth and later expanded to encompass manned spaceflight. This stage culminated in the Apollo program, which saw NASA send…
