Function
This module checks the extent to which a value is inside or outside of a given range. The value is checked in Module 1 to see if it is outside of the range limits. All range limits are checked in Module 2. A value table supplies an example.
Inputs
Type Initial value Description
Lower limit (Input 1) 0 The lower range value
Comparative value (Input 2) 0 The second communication object is assigned here.
The value of this communication object us compared with the range (upper and lower limit)
Upper limit (Input 3) 0 The upper range value
Outputs
Output 1 (send) 0 The result of the comparison is output here.
Output 1 (negates send) 0 The negated comparative result is output here.
A 1-bit value is output.
Output 2
(send by change)		 0 The comparative result is output here.
A 1-bit value is output.
Output 2
(negates send by change)		 0 The negated comparative result is output here.
A 1-bit value is output.
The output does not send on a restart.
Commands
Command (Output 1) - The commands assigned here are run when the value of output 1 is not equal to zero.
Command (Output 1 negated) - The commands assigned here are run when the value of output 1 is not equal to zero.
Command (Output 2) - The commands assigned here are run when the value of output 2 is not equal to zero and when a telegram is sent.
Command (Output 2 negated) - The commands assigned here are run when the value of output 2 is not equal to zero and when a telegram is sent.
Other
Telegram interval 0 Can be changed.
