1. Yes, command 143 in the manual you linked provides this capability.** 2. If ABB's DTM provides a user interface for command 143 ("Trigger Action"), as well as displaying the totalizer value. 3. If ABB's AMS implementation provides a user interface for command 143 ("Trigger Action"), as well...

Displacer type level transmitters with LVDT sensing element that I am familiar with have an LVDT movement range of about one inch. The supported liquid level range typically depends on the length of the displacer. For example, if the displacer is 20 inches long, liquid levels of 0 to 20 inches...

HART multiplexers have been used for remote I/O for many years. For example, the HiDMux2700 [ https://www.pepperl-fuchs.com/en/products-gp25581/42264 ] supports up to 32 4-20 mA channels, providing sensor data via RS-485 (sensors must support HART communication, although conceivably the...

Is the blue trace the voltage across the resistor? If so, why is there activity following your transmit? Usually, device's default address is 0, you should transmit: FF FF FF FF FF 02 80 00 00 82 to poll a device at address 0.

This should work. How do you "generate" a signal? A properly framed message (with preamble, delimiter, address, command, etc.) must be transmitted or there will be no response from the 2800.

Copilot says: The Triconex DI3301, DI3301S2, and DI3301S3 are all digital input (DI) modules used in Triconex safety systems, but they represent different hardware revisions or versions of the same base module. Here's a breakdown of what’s known: Key Differences DI3301: This is the original...

Perhaps something like this: https://www.amazon.com/ZHOFONET-Control-Wireless-Waterproof-Switches/dp/B0BYD3F9BC/ could be adapted.

GWR (Guided Wave Radar) transmitters have no moving parts to wear out.

https://autonomylogic.com/docs/openplc-overview/ OpenPLC Runtime is officially supported on the following platforms: Arduino Uno / Nano / Leonardo / Micro Arduino Mega / Due Arduino Nano Every / IoT / BLE Arduino RB2040 Connect Arduino Mkr / Zero / WiFi Arduino Pro (Machine Control and EDGE)...

There is a possibility that it is powered by the sensed current itself.

I would advise against that; I don't think there are many meters powered by 220 volts. What you really need is a manual or datasheet for the meter that will clarify how it is to be powered.

Is this meter battery-powered? It looks like the two terminals are for the sensing coil, if so, nothing else would connect there. As has already been said, you need to route the wire with the current to be measured through the ring. I like the suggestion, "Try a simple connection with...

According to the manual, for solid red LED: Self-diagnosis found one of the following errors. • Controller error in the major fault level • CPU error (WDT error) The CPU Unit operation will stop, and all outputs will turn OFF...

I suggest use of a solid-state relay, perhaps driven by a PLC digital output, or maybe something like https://www.amazon.com/Generator-DROK-1Hz-150kHz-Adjustable-Frequency/dp/B07P848DYQ?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&psc=1&smid=AFHAE9RJVUMB if you want manual control.

A modern approach is a through-air radar level transmitter; there are devices available for as low as 750 USD.

It was pretty successful. You can see it here: although that was before I upgraded the motor to the one with the link above, which is faster and much more quiet. The main change I made was to ensure that hooking up the battery backwards does not blow the electronics, you can guess how I...

I made something similar once. I used this motor: https://sciplus.com/car-seat-12vdc-gear-motor/ and a motor control board from Pololu: https://www.pololu.com/category/10/brushed-dc-motor-controllers In my case, interfacing to a RC-controlled electronic speed control.

Boot camp provides a way to install / boot Windows on Intel-based Apple hardware. Windows runs essentially the same as on another hardware platform, OSX is not running, there are no additional layers / translation. Apple's newest hardware is not Intel-based and likely will not be able to run...

1. Yes, your HART master would need to send commands to the two device separately (initially based on their Poll Address values which must be different from each other). 2. Yes, your logic makes sense. If the HART master is capable of using Universal Command 3, that returns PV/SP/TV/QV in a...
