DataXport creates logs of run-time or stored data from Data Tables and operand regions within Unitronics PLCs. DataXport saves the data logs in .ulp format. You can open these data logs using DataXport's companion application, DataXls, and then export the data to Excel files.
some time ago I wrote a small application for ammonia storage in chemical factory. Just some measurements, valves and communication to SCADA system.
One day, the guys from the factory asked me to perform a routine check of the system. OK, I arrived to site and had a call with control room about the tests.
One of the prescribed tests was simulating overpressure in the storage and checking if the alarm is sent to control room properly. The emergency valves were electrically disconnected to prevent leakage of the ammonia.
Everything went smoothly, alarm was raised, the control room confirmed alarm so I switched back to real measurement, when...
What the hell? I hear sirens. I just ran out from the equipment room and I saw four red emergency trucks arriving in front of the room. Something went terribly wrong. Maybe the electrician guys disconnected the wrong valves and ammonia leaked due to simulated alarm? My world went black. Emergency situation in the town, probably I will be fired from the company.
I found the leader of the emergency group and I shouted at him: "It was my fault, how dangerous is the contamination?"
The guy replied: "What contamination? We were just asked for a presentation for local TV."
Damn, I will never forget that day.
i'm struggeling to have a UDFB to store the PLC timestamp in a string with the following format: YYYY-MM-DD HH:MM:SS
This is highly needed to insert timestamp values in SQL tables with the datatime field or timestamp field.
I tried to use the RTC to ASCII UDFB but this format is not possible, also not when combining strings. A simple UDFB should do wonders here
This will enter the date of the insert, not the date from the local datastruct.
Good question because we need this also... we need a timestamp value in a locak table structure. Maybe the string format YY:MM:DD HH:MM:SS will work?
I have been using the Jazz2 with the MJ20-Et1 for SCADA connectivity with an Android device. I am trying to troubleshoot some intermittent communication drop outs as well as intermittent inability to connect to the Jazz2 PLC. Can you please explain or point to documentation that clearly describes the following settings in Ethernet Configuration: Keep alive start time, Keep alive interval, and Inactivity timer?
I am struggling to find a guide for connecting initially to the new PLC only units. I am used to the units with screens where you can use UniApp to change the IP address, allowing download from UniLogic.
