Can try a formula that any number will translate to text and if the number is less than or greater than the desired range, to make an inscription Error ?

That is, in fact, any correct number will be text and not the number itself.

Never tried that.

Line 514, column 10:
See the file C:\SCADA\ScadaServer\Log\CalcEngine.cs with the source code

See the file for this line and the error symbol

what if two doors close at the same time ? 🙂

[manjey73]

Yes, we need a formula.
Make a calculation channel, specify the use of the formula. As a formula, specify

DateTime.Now.ToOADate()

Set the display format to Time, Date or Date and Time

Display the channel in a table or scheme

Using Modbus in Siemens PLC

Thanks, look. I’m really gonna have to deal with the DF1, the Micrologix controller.

[manjey73]

Look for formulas to check the signal status on the forum or try to change the formula to double.NaN

Does your PLC work via Ethernet or com port ? Can you make a log of Wireshark or monitoring program for COM port and put on the file exchanger ?
With the exact model of PLC ? and the type of exchange Protocol ?

We need to spread the devices on different physical lines of communication.

[manjey73]

Could you share the wireshark logs that you received by scanning the packets ? If anything, there is the Allen Bradley Protocol.

You can check if this applies to Modbus using this link
Rapid SCADA Modbus Parser
However, you need to find the right start and end of the parcel in the TCP scanner

[manjey73]

There is a similar task, but AB Micrologix is used, according to the description PLC data support Modbus, but it is used or not unknown. You must put the port watcher on the exchange between the PLC and the HMI panel to read the traffic between them. But not the fact that it will help. Plus, try to connect to the PLC with Modbus scanners.

Tell me, why do you then need to input 1 ?

[manjey73]

It is also necessary to transfer the configuration of the module settings. And also buy a license for the module on RaspberryPi

[manjey73]

If the server is one of the main, the Rapid Gate is not needed.

If there are several servers plus one main server, then Rapid Gate is needed for each slave server and the corresponding number of licenses for each Rapid Gate is required.

A large diagram is specified without Rapid Gate
