Writing issue: use Matrikon OPC to compare. If it works, the cause is related to the particular OPC.

Try unblocking PlgSchExtraComp.dll
Example

Hi Phachakorn,

Does ‘C:\SCADA\ScadaWeb\bin\PlgSchExtraComp.dll’ file exist?
What is the installation directory of Rapid SCADA? I suppose C:\SCADA\

Note: Because your company purchased Extended support subscription, you also can solve issues by email or ticket tracker which is faster than forum. It’s up to you.

> Tag value has been passed to OPC server. Name: PLC1.Generic.sensor-nivel-bajo-tanque-principal

The above line says that the command is sent.
What OPC server do you use?
Can you try sending commands to Matrikon OPC for testing reason?
What communication protocol is used by the PLC?

Hi,

Could you provide screenshots of the settings and of the web app?

[Mikhail]

I don’t check formulas posted on the forum. This is just an idea. Creating well tested formulas is a commercial service.

[Mikhail]

Semicolon splits a formula into 2 parts. 1st for value, 2nd for status.

The details is here http://doc.rapidscada.net/content/en/software-configuration/using-formulas.html

[Mikhail]

Please check the version of Scheme Editor.
Also look the editor log for an error details.

Option 1. You can change this line and rebuild Report.dll

Option 2. You can purchase a modification of the plugin to allow editing this value in the plugin settings.

[Mikhail]

1. 32 is a constant in the source code. If we increase this value, the performance becomes slow.

2. Yes, you need a formula of in input channel like the following:
Stat > 0 ? Cnl : Val(); Stat > 0 ? Stat : Stat()
Be careful, because a connection issue would not be detected in time.

3. It’s possible to create formulas that performs the required calculations. It can be done as a part of our consulting service. This is out of free support.

4. 32 days limit applies only if you choose a daily period. In case of using monthly period, there is no such limit.

How to setup the output channel to connect a toggle on the web to a coil in ModBus?

I suppose, the output channel shown in your screenshot is OK. May be you need a formula, decide after watching command values in Communicator.

[Mikhail]

but since is a toggle switch, what should be the command parameters. I don’t know how to setup the output channel for the ModBus, do you have any example?

Let’s watch in the Device Data page what command value is passed to Communicator.

[Mikhail]

The installer.cs should be helpful.
