Siemens S5 Header Protocol
The Siemens S5 Header protocol serves the data exchange between PLC
systems. Deploying the organization format (short ORG) that is included in
the Siemens S5 Header protocol, a short description of a data source res.
destination in PLC environment is possible.
The used ORG formats are corresponding to the Siemens specifications
and are listed in the following table.
The ORG block is optional at READ and WRITE.
The ERW specification is irrelevant for the Ethernet coupler.
The start address and the number are addressing the memory area and
are stored in HIGH-/LOW format (Motorola – Address format)
Description Type Area
ORG specification BYTE 1..x
ERW specification BYTE irrelevant
Start address HILOWORD 0..y
Number HILOWORD 1..z
The following table lists the useable ORG formats. The "length" may not be
specified as -1 (FFFFh).
