Example of a parameter and the explanation:
Data Type Range read/write Secured DDE Proc/par
Valve output unsigned long 0…16777215 RW  Y 55 114 1
unsigned long = one of the data types below.
Unsigned char 1 byte integer
Unsigned int 2 bytes integer, MSB first
Unsigned long 4 bytes integer, MSB first
Float 4 bytes IEEE 32-bit single precision numbers, MSB first
Unsigned char [] array of characters (string)
RW = R - parameter can be read, W – parameter can be written.
Secured =  Y =Parameter is secured. N= Parameter not secured.
0…16777215 = Parameter range.
DDEpar. = 55 = FlowDDE parameter number
Proc. = 114 = Process number
Par. = 1 = process parameter number
Another example is:
Data Type Range read/write Secured DDE Proc/par
Fluid name unsigned char[10] a…Z, 0…9 RW  Y 25 1 17
unsigned char[10] = Data type Unsigned char[], array of characters. [10] = number of characters.
RW = R - parameter can be read, W – parameter can be written.
Secured =  Y =Parameter is secured. N= Parameter not secured.
a...Z = characters which can be used in the string
0...9 = numbers which can be used in the string
DDEpar. = 25 = FlowDDE parameter number
Proc. = 1 = Process number
Par. = 17 = process parameter number
secured parameter:
To enable secured parameter, see chapter 9 SPECIAL PARAMETERS 9.2 INIT/RESET.
