How to specify a value in “send command now” button

[SergiScada]

Hi there,

I have created a Com Line qith a Modbus device and everything is working fine. But I have a question. I am creating a new Schema for this device and I am trying to create some buttons to send commands to the device in order to write some values in the registers.

I have defined the command in the Modbus device properties but I noticied that if the button has the “send command now” type I cannot specify the value to send with the command. I want to know if it’s possible to specify this value.

I see that when i press the button in the schema the command is sent but the value is always “0” i want to specify this value, but i don’t want to be asked for this value every time i click the button i just want to define a static value for the action.

Regards,

Sergio D

You need to specify what you need in the formula for the control channel. Send now always sends 0 if you don’t apply the formula.
