Support Questions / Resetting values to default when communication to PLC is lost

« on: February 10, 2021, 05:03:51 AM »

Hello Everyone,

I am looking for a way to reset integer values to 0 or bits to off when communication to a PLC is lost and restart reading correct values when communication is regained. What is happening in my application is that when values are read and communication is lost, the values keep on alternating with "ReadTimeout". I am using BasicDatalogger2 to log the values to csv file which I automatically upload to MySQL database with a php application. The values read before loss of communication keep on logging to the csv/database.

Support Questions / Single window display of alarms from multiple PLCs

« on: December 15, 2020, 02:28:19 AM »

Is there a better way to display alarms from multiple PLCs? In my case, I am using two components of MessageListByItem, each collecting alarms from two PLCs. I want to display all alarms from multiple PLCs on one window

Yes, it is very possible to make the arduino pins on or off.

I have done this before with ModbusTCP by attaching an ethernet shield on Arduino mega.

I followed the link but the explanation is not clear to me. It seems messagelistbybit can be configured for 1 PLC address. I want alarms from multiple PLC addresses. Would you please elaborate

I would like to display multiple alarms as they occur. Which tool is best suited for this an how to use it? For example, an alarm that a pump has tripped, overcurrent etc

Thanks Archie,

Swapping bytes did the trick. Now able to read the same value seen in serial monitor.

Am using Ethernet. I have set my PLC address to 40001. I have included modbus.h library in the arduino code

Am using digitalpanelmeter to read temperature from arduino. In serial monitor, am getting 27 degrees and getting strange readings on the panel meter, 6298 degrees. What could be the cause?

I would like to access advancedHMI on a client computer from a server. Any advice? I don't want the solution file to be accessed by the client.
