Siemens S7-200 Driver
Caution: When modifying Word, Short, DWord, Long and Float types remember that each address starts
at a byte offset within the device. Therefore, Words V0 and V1 overlap at byte 1. Writing to V0 modifies the
value held in V1. Similarly, DWord, Long, and Float types can also overlap. It is recommended that these
memory types be used so that overlapping does not occur. As an example, when using DWords, use V0, V4,
V8, and so on to prevent overlapping bytes.
S7-200 PPM Addressing
The S7-200 PPM addressing format is the same as the S7-200 addressing format. The model selection in
this case determines whether the driver is using PPI protocol (normal S7-200 Mode) or PPM (S7-200 in Point
to Point Modem) mode. In both cases, the addressing is the same. PPM mode is used when the target PLC is
connected via the EM241 Modem module or via the programming port running in 10-bit mode.
The default data types for dynamically defined tags are shown in bold.
