Example 3: Data should always be received conditionally and then retrie-
ved; the following conditions are defined with the Receive Mode com-
mand.
- Two start characters
- Two end characters
- Receive-data length
- Two BCC
- Single abort characters
- Four abort characters
Command 1: Select Mode
DW0 - DW4 = Reserved for R5REQ
DW6 = 'MD' Command identifier
DW8 = K0202H Two start, two end characters
DW10 = 'ss' Start characters
DW12 = 'ee' End characters
DW14 = K0214H Two BCC, single, 4 abort
DW16 = 'aa' Termination
DW18 = 'aa' character
DW20 = 100 Return interlinking depth in marker byte
100 if a fault occurs.
Command 2: Unrestricted Receive
DW32 - DW36, DW62 = Reserved for R5REQ
DW38 = 'RX' Command identifier
DW40 = 10 Monitoring time = 100 ms
DW42 = 100 Size of the PLC Receive buffer = 100
DW44 = 150 Receive-data length = 150 characters
Command 3: Data Copy
DW64 - DW68, DW94 = Reserved for R5REQ
DW70 = 'DC' Command identifier
DW72 = K44H Identifier
DW74 = 11 for
DW76 = 0 PLC Receive buffer
Command 4: Start
DW96 - DW100, DW126 = Reserved for R5REQ
DW102 = 'ST' Command identifier
DW104 = K44H Identifier
DW106 = 10 for
DW108 = 0 Command chain
DW110 = 2 No. of the job parameter lists which should
be transferred
DW112 = K0201H Co-position number of commands
First Receive Mode, then Receive
DW114 = K00FFH End of command chain
Only the parameter list for the Start command is started with the R5REQ.
The other commands in the command chain are started by BÜP03E ac-
cording to the specified sequence. The "DW112 = K0201H" command
sequence specifies that the command with position number 1 (Receive
Mode) is executed before 2 (receive). The Data Copy command is started
parallel to the command chain.
