Why didn’t you use my template ? It is checked since I used this relay Board

can’t you see the difference between what ModbusPoll sends and yours ? ModbusPoll adds the calculated Checksum to the query. You do not add a binary command when you send it. The relay works with HoldingRegisters requests, you are trying to work with Coils

Where did you get this template ?

[manjey73]

This relay works on Modbus RTU, just the author tried to connect it first through an Ethernet – RS485 Converter and got confused.

Disable the Bound checkboxes in the Communicator Windows and check the line operation.

OR

Configuration Database – table Devices – Address

[manjey73]

When there are Bound checkboxes in the settings, the device address is taken from the Scada database. When the checkboxes are removed, the parameters are taken from the Communicator window.

Maybe that’s the problem? do you have an address binding in the Scada database ?

And you send a string, and it is necessary to send Hex

Siemens Sentron PAC3200 has an Ethernet port ? Some PLCs with an Ethernet port require you to also enter the address for the RTU network when connecting over Ethernet

[manjey73]

Does your interface Converter have a 502 port to work with the RS485 port ?

Also show the Custom Parameters and Request Sequence tabs. And check the documentation, the link to which gave Michael settings for these tabs.

Where are your Line Parameters ?
Unfortunately I have version 5.7.1 installed and I no longer have a separate window of the Communicator app

you can create buttons for sending commands by writing (I do not know in what place in English) in “command Value” ‘; Off ; On’ or ‘; On ; Off’ without quotes but that at the beginning there was a symbol ; thus in Cmd 1 or 2 will be sent and then in the formula of the control channel to make Cmd*256 and you in one case will be sent 256, in the second case 512.

[manjey73]

In the control channel it is necessary to give the command 1 multiplied by 256, 512 or 768 One turns off, another turns on, the third performs a trigger function. For Example, Cmd*768

Template for relay

Template for this relay

[manjey73]

No, you don’t have to. It is part of RapidScada and is free. The source codes of the kernel and all open system drivers are also available on GitHub

[manjey73]

Sorry, are you talking about the Siemens PAC3200 ? Yes, it has registers in double format, you just read a group of registers, and glue them together in Scada using formulas.

The current Modbus driver is able to work with Double directly

The Rapid Scada database works and stores data in double format. It works perfectly with these formats.

[manjey73]

Get a new theme, I’ll lay out a template for this relay and channel settings
