Example
The project in the example requires 4 integer values, 2 hexadecimal fields with bit
information and 1 real value.
Machine data:
MD14510 USER_DATA_INT[0]
123
MD14510 USER_DATA_INT[1]
456
MD14510 USER_DATA_INT[2]
789
MD14510 USER_DATA_INT[3]
1011
...
MD14512 USER_DATA_HEX[0]
12
MD14512 USER_DATA_HEX[1]
AC
...
MD14514 USER_DATA_FLOAT[0]
123.456
GP Parameter (OB 100):
CALL FB 1, DB 7 (
MCPNum :=

MCP1In :=
P#E0.0,
MCP1Out :=
P#A0.0,
MCP1StatSend :=
P#A8.0,
MCP1StatRec :=

BP parameters (to scan runtime):
l gp_par.UDInt;
//=4,
l gp_par.UDHex;
//=2,
l gp_par.UDReal;
//=1 )
During PLC power-up, DB20 was generated with a length of 28 bytes:
