• Read/write of the PrX parameter
A = value of the PrX parameter
• Read/write of the PrX parameter
B = value that depends on the values of A and PrX
• Read-only parameter
PrX indicates the value of A which can also be binary
• Read/write of binary parameter
The position of the switch indicates bx.y=0
• The value of the binary parameter bx.y positions the switch.
• If A is less than B, C=1 (true). Otherwise, C=0 (false)
• The value of G is the lowest value of A B C D E F.
• Only if A = 1, B = 1 then C = 1, otherwise C = 0
• If A or B is equal to 1 C = 1, otherwise C = 0
• C = A - B
• values coming from the hardware
• values sent to the hardware
• the value of A is converted to B. For example, if A/D is
displayed in the triangle symbol, the analogue value of A is
converted into the digital value B
• The maximum value of A will be PrX.
