Want to Control Input Data Overflow

[SachinKumar]

Hello everyone,
My name is Sachin and i have one query.
I have a device that is connected remotely via Rapid Scada on Modbus, That device is connected with one sensor whose value is shown in our localhost in table view.
If someone remove the sensor as physically from device then it becomes data overflow and i got 65526 value displayed in table view.
I want to control this process as if someone remove the sensor then the values shown in table would be like -1 and when someone connect it again then it should show the actual value present.
i Want to control this whole process automatically.

Hello,

Do you need to display 65526 as -1?

[SachinKumar]

Actually we can do that using formula,
What I want is,
Suppose if Input Channel(101) > 65525 then it shows -1 otherwise it shows the actual value

One More Question, How can we use custom Formulas in Rapid Scada?

Channel(101) > 65525 then it shows -1 otherwise it shows the actual value

Use the formula for the channel 101:
Cnl > 65525 ? -1 : Cnl

Hello Mikhail,
I have one query , Actually I have 4 Input coil sensors which are communicated via modbus. What I want is I want to control all Senosor On-Off using one single button in scheme ediitor but I am not getting any idea how to do that!
Please help!!!!!!

Hello,

If the device support multiple command function, you can add a such command to the Modbus template in order to change all coils by single command.
Also you can use Automatic Control Module to send 4 commands according to a single command.
