OBJECT_REQ and OBJECT_RSP for 8 byte process data channel
2.11.9 VX
65
Example:
P196 Bit 0..2 = "4" (8 Byte process data),
P196 Bit 7 ="0" (PD1/2 = STEUERWORT / STATUSWORT),
P196 Bit 5 = "1" (OBJECT_REQ and OBJECT_RSP can be temporarily assigned to PD),
P196 Bit 6 = "0" (OBJECT_RSP automatically assigns PED as answer to OBJECT_REQ)
Basic setting for PAD with P139="6322688" (LAGE_ZIEL=PAD3-6) and P142="6289152"
(OUTPUT_WORD=PAD7-8) and for PED with P135="6317056" (LAGE_IST=PED3-6) and P138="6289408"
(INPUT_WORD=PED7-8)
In this example you should make a backup copy of the contents of LAGE_ZIEL and OUTPUT_WORD before you
switch to OBJECT_REQ.
